概
述
随着石油勘探开发事业的发展,钻井技术的进步给固井提出 更高的技术要求。用纯水泥固井已成为过去,一代又一代的油井 水泥外加剂问世,用以改善水泥浆性能,使之能适应深井或超深 井、特殊井复杂地层等的固井施工,达到封隔地层、支撑套管和 地层、保护油气层、延长油井寿命和提高石油采收率的目的,同 时外加剂的应用水平的提高反过来也促进固井技术的发展。如今, 固井工程已成为石油工程、化学工程、硅酸盐科学、高分子科学、 流变学等多学科互相渗透的综合学科。
第二节 油井水泥外加剂
在钻井过程中,水泥的用量是相当大的。油井水泥的外加剂 是用来调整水泥浆性能的化学助剂。50年代,固井被看作是一门 “技艺”,而70至80年代它已成为多种学科互相渗透的综合科学 “固井学”了。外加剂的作用和地位超过了水泥本身,有人认为 “油井水泥总是作为外加剂的载体用于固井工程中”。外加剂是 指掺入量小于或等于水泥重量5%,主要通过物理或化学的作用使 水泥浆达到某种性能。油井水泥外加剂主要可分八大类型:
未能及时监测到油气上窜,井控失效
– 负压力测试解读错误,油气井完整性未满足要 求,就进行下一步的施工 – 井控监督未及时下达指令 – 紧急停车系统失效,造成油气点燃
油气在深水平台上点燃
– 导流至泥浆天然气分离装置时天然气泄漏至钻 机平台 – 消防系统未能组织油气点燃
紧急封井器未能及时密封
– 紧急封井器未能封住井口
环空水泥密封性差
充氮水泥体系复杂,影响因素
多 水泥浆体积少,易受污染(充 氮水泥45桶) 未加降失水剂
未进行全面的室内实验
充氮水泥可能稳定性差,氮气 会上窜

水平井测井技术的使用条件
随着井斜角的逐渐增大, 井下仪器与井壁的摩擦力Ff也 不断增大,井下仪器向井底方 向运动的分力FB逐渐减小(图 3)。当井斜角增大到约65° 时,井下仪向井底方向运动的 分力FB减小到一个临界值,即 该分力约等于井下仪器与井壁 的磨擦力,这时,井下仪器再 也无法借助于自身重力向井底方向运动,测井电缆下放井 下仪器的作用消失。因此在井斜角大于 65°的大斜度井和 水平井中,必须借助外力将井下仪器推至井底,以便进行 测井。

俄罗斯固井质量测井仪器与哈里伯顿INSITE系列测井系统的挂接
俄罗斯固井质量测井仪器与哈里伯顿INSITE系列测井系统的挂接【摘要】本文介绍了俄罗斯固井质量测井仪器的基本特性及功能,重点是解决了实际生产中不同测井系统挂接的需求。
针对俄罗斯固井质量测井仪器与insite系列测井系统挂接之间存在的问题,包括gector地面采集系统的挂接;gector地面采集系统深度信号的获取;地面系统的供电组成;井下仪器3芯接头与insite系列19芯接头的转换问题等,提出了合理有效的解决方案,实现了两套不同系统之间的挂接,充分利用测井资源,提高了测井生产时效。
【关键词】声波变密度水泥胶结质量仪器挂接地面采集俄罗斯固井质量测井仪器即俄罗斯mak2—sgdt测井系统,采用声波变密度(mak2)和伽玛密度(sgdt)测井仪器相结合的组合形式定量的评价水泥胶结质量。
这套系统主要包括声波变密度测井仪、伽玛密度测井仪、gector地面采集箱、mak电源箱。
insite系列测井系统是美国哈里伯顿公司在excell2000系列测井系统基础上研制的新一代测井系统。
俄罗斯固井质量测井仪器和insite系列测井系统在测井中具有很大差异,测井系统整体结构大相径庭。
而俄罗斯固井质量测井仪器可以与insite测井系列在测井过程中的功能互补,通过两套系统的挂接,使两套系统在实际测井操作中协调工作,共同发挥它们的作用。
1 俄罗斯固井质量测井仪原理俄罗斯固井质量测井仪器采用声波变密度(mak2)和伽玛密度(sgdt)仪器相结合的形式评价水泥胶结情况。
mak2不提取首波绝对幅度的大小,而是研究首波的幅度衰减和时间特性;它测量首波到达接收器的时间、接收器记录的首波衰减、首波时差及首波衰减系数。
因此,mak2声波变密度仪器是通过测量首波衰减情况来评价第一、第二界面胶结质量。
sgdt伽玛密度仪器是通过放射源来反映水泥环的密度情况。
经过计算机处理,能够得到套管壁厚曲线、偏心率曲线、水泥平均密度曲线等。
通过这两种仪器测量的成果曲线信息,结合常规资料和地层密度等资料进行综合解释,综合评价水泥胶结质量、确定水泥返高和自由套管井段、检查套管损坏位置、检查套管程序以及确定套管相对与井壁的偏心率等。
国外页岩气水力压裂技术及工具一览
国外页岩气水力压裂技术及工具一览页岩储层具有超低孔低渗特性,钻完井后需要压裂改造后才得到经济产量。
国外油田服务公司最新工具达到了很高水平,水平井裸眼封隔器投球滑套分段压裂技术用高强度低密度球级差达到1/16in,封隔器耐压差达到70MPa,TAM公司自膨胀封隔器最高可达302 °C ;泵送桥塞射孔分段压裂技术所用桥塞可分为:堵塞式、单流阀式和投球式复合桥塞,桥塞耐压差达103.4MPa,耐温232 °C ;哈里伯顿CobraMax H连续油管喷射工具系统,目前最多达到44段。
这些为国内页岩气水力压裂完井方式与压裂工具的选用打下基础。
从应用工具角度看,分段压裂工艺方面主要包括:水平井裸眼封隔器投球滑套分段压裂技术,泵送桥塞分段压裂技术,水力喷射分段压裂技术。
从压裂工具方面分析,目前页岩气压裂技术有可膨胀封隔器/裸眼封隔器+滑套多级压裂,泵送桥塞射孔压裂联作多级压裂,水力喷射压裂等。
在美国的页岩气开发技术中,可膨胀封隔器/裸眼封隔器+滑套多级压裂,泵送桥塞射孔压裂联作多级压裂技术比较成熟,使用比较广泛,可适用于较长的水平段;水力喷射压裂可实现准确定位喷射,无需机械封隔,节省作业时间,非常适合用于裸眼井、筛管井以及套管中井。
1、水平井裸眼封隔器投球滑套多级压裂系统封隔器投球滑套多级压裂技术一般采用可膨胀封隔器或者裸眼封隔器分段封隔。
根据页岩气储层开发的需要,使用封隔器将水平井段分隔成若干段,水力压裂施工时水平段最趾端滑套为压力开启式滑套,其它滑套通过投球打开,从水平段趾端第二级开始逐级投球,进行有针对性的压裂施工。
水平裸眼井多级压裂目前已经是北美页岩气压裂开采主要技术手段,并越来越受到作业者的欢迎。
水平井多级压裂技术关键在于封隔器(压裂封隔器和可膨胀封隔器)和滑套可靠性和安全性能,尤其是管外封压裂管柱的可膨胀封隔器和开启滑套的高强度低密度球材料决定技术的成功与否。
目前国外油田服务公司都有自己成熟的工具,高强度低密度球级差达到1/16in,封隔器耐压差达到70MPa,TAM公司耐高温自膨胀封隔器最高可达30 °C 。

It is based on using a Swage Packer to seal the base of the liner into the old casing or a screen. Briefly, a Swage Packer is a thin wall pipe with a vulcanized rubber cover that can be expanded radially using a high-pressure inflatable packer to create a well seal. The attached drawings P663A and P663B show the two most common methods of applying this technique.The first of these shows re-lining using a swaged packer and cementing the annulus between the liner and the existing casing. The basic installation steps, as indicated on the drawing are: • Clean the existing casing and inspect to ensure it’s ready to receive the liner. In some cases, this may require a deviation survey in addition to video inspection.• Attach the Swage Packer and one-way grouting valve assembly to the 1st joint of the liner. The drawing shows this as a welded connection but threaded or even glued and pinned connections are also possible.• Run the liner in to the required depth. Note that, if the liner is to tie back to the surface, the liner can be run as usual, however, it is also possible for the liner top is to terminate below surfacewhich is described below.• Make-up the High Pressure Swaging Packer, straddle pipe and low pressure cementing packer.• Run this assembly inside the new liner to locate the HP Swaging Packer adjacent to the Sage Packer. The two different packers each have separate inflation hoses to allow independentoperation.• Inflate the HP packer to sufficient pressure to deform the Swage Packer out into firm, sealing contact with the existing casing. This operation is controlled in terms of both inflation pressure and volume against pre-tested standards for each.• With the HP packer still inflated, inflate the LP cementing packer to isolate the one-way cementing valve.• Hook up a pumping head to the drill rods and establish circulation to the liner/casing annulus with water then switch over to cement grout and pump grout to fill the annulus.• Deflate the LP cementing packer and flush the excess grout out of the rods and straddle zone.Obviously, to minimize flushing, a water tail can be pumped following the cement and thestraddle pipe can also be set-up to accept a wiper plug if required.• To complete the re-lining simply deflate the HP packer and trip out of the hole.The liner can be manufactured from any compatible material, e.g. standard steel casing, PVC, ABS, FRP, etc. Since the liner is not deformed in any way and the Swage Packer will be expanded to a larger ID than the liner, it’s the liner itself which determines the minimum finished ID of the lined well. Selection of the liner will depend on factors such as minimum running and grouting clearance, method of joining, well fluid conditions, minimum allowable ID and, inevitably, availability.If using a thin wall or other low collapse strength liner, a third inflatable packer (or other closure method) may be run at the surface and the annulus between the drill rods and the liner can be water filled and slightly pressurized to prevent collapse during cementing. In this case it essential to pump a water tail after the grout, preferably with a wiper plug, as the liner must remain pressurized until the grout has reached initial set at least.The 2nd re-lining technique shown involves deforming both the Swage Packer and the liner. In this case, they are both usually manufactured from the same size pipe – either stainless steel or carbon steel as appropriate to the installation. The installation procedure is similar to that given above except for the steps involved in cementing the annulus. In their place, after performing the initial setting of the Swage Packer, the HP packer is deflated, moved up hole and re-inflated to swage out the liner. This process continues in a stepwise fashion until the complete liner has been swaged out.Normally, it is the swaged ID of the Swage Packer which represents the minimum ID of the lined well in this case. Typically, for water wells, this will be around ½” (13 mm) less than the existing casing ID and thus represents a minimal reduction of diameter.As mentioned above, it is possible to locate the liner top some depth below surface. In this case, following make-up of the liner to the length required, the liner is hung off and the packer assembly is run into the liner on drill pipe. Locating the HP packer adjacent to the Swage Packer, as previously, this packer is inflated to a pressure sufficient to provide a high strength anchor on the inside of the liner but less than that required to begin setting the Swage Packer. The liner is then lowered to its required depth using the drill pipe and the frictional anchor provided by the inflate HP packer. On depth, the pressure in the HP packer is simply increase to set the Swage Packer.Apart from the obvious advantages of these techniques to produce very slim-line re-lines, it may be noted that at no time is a conventional drill rig required. All operations may thus be performed using a crane and simple casing & rod slips thus reducing costs and scheduling constraints. Furthermore, there is no need to kill a producing well, even an artesian well, in order to reline using these techniques as the inflatable packers may be used, in conjunction with appropriate surface equipment, to prevent contamination of the aquifer with cement or uncontrolled flow situations.The Slim-line Re-lining techniques described were first introduced by AGE Developments Pty Ltd (AGE) of Perth, Western Australia in 1993 and are offered internationally by Inflatable Packers International (IPI).By Clem Rowe, Managing Director, Inflatable Packers International Pty Ltd © 30 June, 2000。

CementingHALLIBURTONHT -400™ PumpThe Industry StandardH alliburton’s HT-400™ Pump is a lightweight,rugged,versatile unit that was introduced in 1957.Its name denotes Horizontal Triplex and its original rating of 400 horsepower.Since its debut,the basic design has been improved and upgraded until it now is rated at 800 hp maximum in some configurations.The pump has performed millions of operating hours in fracturing,acidizing,cementing,and sand and water control work.FeaturesThe Halliburton twin-pump or flexibility concept is particularly useful when precise pumping ranges andcontrols are required.Halliburton exclusively manufactured the HT-400 pump power end,so that practically all parts are interchangeable.The exception is that the power end case is built in both left- and right-hand configurations.Internal parts,including the proven worm/ring gear sets,are identical,only the case is different.Power ends can be fitted with any of the five sizes of fluid ends – 3 3/8”,4”,4 ½”,5”and 6”plungers – each with characteristics suitable for specific applications.Power end components:•Case and Drive Gears:Power End cases aremanufactured exclusively by Halliburton in both left- and right-hand models.They are made of high-strength weldments of Halliburton design.They are not interchangeable.•Crankshaft:Heat-treated steel forgings are used to manufacture crankshafts.All cranks are the same,even for left- and right-hand units.•Connecting Rods:Connecting rods are made from aluminum forgings.The identical rods are internally drilled to provide lubrication to the crosshead pins.•Crossheads:Crosshead bodies are made of heat-treated steel alloy castings.They are fitted with replaceable,high-leaded bronze shoes on both top and bottom.•Lubrication:Standard self-contained power endlubrication system is pressurized by an internal crescent gear-type pump driven off the end of the worm gear.Positive pressure lubrication is supplied to the crosshead slides,gear support bearings,crankshaft throws and crosshead pins.•Cooling:Tube-and-shell coolers are optional add-on components,which provide remote cooling capacity.The HT-400 pump can be fitted with radiator-type,air-to-oil or water-to-oil cooling systems as well.Spacers are special components designed to separate the fluid end from the power end of the HT-400 pump.The interchangeable spacer insures that fluids being pumped do not contaminate the power end and cause premature failures.Each fluid end package is manufactured from three separate chambers – all identical and completely interchangeable.If one chamber of a fluid end should cause trouble,it can be changed quickly and the pump returned to duty.Fluid End components:•Chambers:The fluid end is constructed from threeseparate but identical forged and heat-treated chambers.Fluid ends can be supplied in any of five plunger sizes and each size can be fitted to the standard power end without alteration of either fluid or power end.•Valves and valve seats:Fluid ends are fitted withreplaceable,carburized valves and seats of Halliburton design and manufacture.Most of the valve assembly parts are interchangeable between suction and discharge ports within a given size and some are even interchangeable between sizes.•Lubrication:A separate lubrication system supplies lubricant to the fluid end package.H A L 17345Fluid end viewSales of Halliburton products and services will be in accord solely with the terms and conditions contained in the contract between Halliburton and the customer that is applicable to the sale.H04798 04/06© 2006 Halliburton All Rights ReservedPrinted in U.S.A.TestingEach HT-400 pump undergoes rigorous testing before it is placed in service.Fluid end chambers are tested individually to pressures far beyond the anticipated operating pressures and then tested again when they are assembled into three-chamber fluid ends.A third test is performed after the fluid end is attached to the power end assembly.Power ends are submitted to equally rigoroustesting in a Halliburton test facility.Pumps are run for over an hour at various speeds and at various pumping pressures before they are installed on a unit.After the unit is completed,each pump is further tested during the unit checkout.H A L 17346Mounted on a skid — close-upFluid end ring gear viewMounted on Advantage™ skid unit — side viewH A L 17347H A L 17348。
水下释放塞固井工艺.
水下释放塞固井工艺水下释放塞固井工艺是一种用于浮式钻井平台(船)或半潜式钻井平台的固井工艺。
固井所需的上、下胶塞是在组装套管头时通过下入工具一起装在套管头以下的套管内, 固井期间分别用钢球和钻杆塞释放下胶塞和上胶塞。
南海海域常用的有两种方法:1. 哈里伯顿(Halliburton)水下释放塞固井方法(Sub-Surface Release Plug Cementing Method 简称SSR)见图6-18所示。
(1)SSR系统组成:①上、下注水泥胶塞联合体;②压力平衡阀;③钻杆胶塞(释放上胶塞);④释放球(释放下胶塞);⑤钻杆水泥头。
(2)操作方法:①将固井上、下胶塞联合体与压力平衡阀连接好以后装在钻杆的下部直接下入套管头以下的套管内, 将钻杆水泥头接在井口送入管柱的顶部。
图6-18 哈里伯顿水下释放塞固井方法释放球和钻杆塞同时装在钻杆水泥头里;(Sub-Surface Release Plug CementingMethod)②注水泥前投球, 让其通过钻杆坐入下胶塞的球座上, 开泵增压使下胶塞脱离胶塞联合体;③注完水泥后, 投放钻杆胶塞, 驱除钻杆内水泥,当它到达上胶塞后, 泵压上升释放上胶塞,通过上胶塞顶替水泥浆直到碰压。
2. BJ水下注水泥系统(Subsea Cementing System)(1) 系统组成(见图6-19):上、下胶塞联合体;(2)下入工具总成;③释放球;④钻杆胶塞;⑤钻杆水泥头。
(2) 操作方法:①将上、下胶塞联合体装在下入工具的下部;②将下入工具装在钻杆的底部, 并用钻杆送入套管头以下的套管内;③注水泥前投球, 让其通过钻杆坐入下胶塞的球座上, 开泵增压使下胶塞脱离胶塞联合体;④注完水泥后, 投放钻杆胶塞, 驱除钻杆内水泥, 当它到达上胶塞后, 提高泵压释放上胶塞,通过上胶塞顶替水泥浆直到碰压。
(5)释放上、下胶塞所需泵压见表6-34。

HAL21998
® ® Delta Stim 完井技术采用Delta Stim增产滑套和Swellpacker 封隔系统。完井设定为投球打开方式。
Delta Stim® 完井技术为操作人员提供一个多层水平井 完井的新选择,可以达到最小化或无干扰的精确定位压 裂。该服务集合两大可靠工具于一身,即Delta Stim® 增产滑套和Swellpacker®封隔系统,使得操作人员可在 单井眼多产层选择性地开采,并可在日后封隔一个或多 个产层。Delta Stim完井装置可随VersaFlex®尾管悬挂器 系统一起下入,安装简单可靠。
3. 随着工作管柱下入到位,需要在膨胀式封隔器 (Swellpacker)系统周围的环空中加入液烃(如柴 油),从而引起膨胀。
4. 用带有坐落头的泡沫塞顶替液态碳氢化合 物。当泡沫塞到达并密封浮箍时, 完井管串中即形成压力密封。
5. 试压完井管串或尾管及浮箍
6. 此时,如果要下入尾管,则尾管悬挂器必 须座封。
2. 下入管串及工具到位,使滑套位于措施层
3. 工具下到位后,将液态碳氢化合物
(如柴油)替入环空,使膨胀式封隔器浸在其 中,促使胶筒膨胀。

井下工具详细介绍
技术要求
1、下管柱时,管柱上提高度必 须小于防坐距(Y211),一般不得 超过0.4米,否则会使封隔器中途 坐封。如遇封隔器中途坐封时,可 上提管柱1米左右,解封后继续下 管柱。 2、在井下条件允许时,封隔器 下部应按30-40米尾管。 3、坐封封隔器的坐封高度,决 定于下入深度、坐封载荷和胶筒密 封压缩距等因素。

一、用途 用于分层试油、采油、找水、 堵水、压裂、酸化和防砂。 二、结构如图所示。
Y221封隔器工作原理
坐封;按所需坐封高度上提管柱旋转管 柱。因扶正器依靠弹簧的张力造成扶正块 与套管壁的摩擦力沿轨迹中心管的轨迹槽 运动,滑环销钉从短槽的上死点运动到坐 封位置时的长槽的上死点,卡瓦从收拢状 态变成撑开状态(被锥体锥开),并卡牢 在套管壁上。同时坐封剪钉被剪断,上接 头、调节环和轨迹中心管下行,压缩胶筒, 使胶筒的直径变大,从而封隔油,套管环 形空间。 解封:上提管柱,上接头、调节环和轨 迹中心管一起上行。滑环销钉运动到下死 点,锥体退出卡瓦,卡瓦收回解卡;胶筒 收回解封。
