.目前在中浅层试油施工中出现的干层、水层、气层及异常高压等特殊层位,为方便后续试油,封堵废弃层位,通常采用该类桥塞进行封层,同时对于部分短期无开发计划的试油结束井也采用永久式桥塞封井。

此外,该桥塞也用于深层气井的已试层封堵,为上返测试、压裂改造等工艺技术的成功实施提供保障。

工作原理:利用电缆或管柱将其输送到井筒预定位置,通过火药爆破、液压坐封或者机械坐封工具产生的压力作用于上卡瓦,拉力作用于张力棒,通过上下锥体对密封胶筒施以上压下拉两个力,当拉力达到一定值时,张力棒断裂,坐封工具与桥塞脱离。

此时桥塞中心管上的锁紧装置发挥效能,上下卡瓦破碎并镶嵌在套管内壁上,胶筒膨胀并密封,完成坐封。

结构与特点:永久式桥塞外观图见图1,结构有如图2所示几个部分组成:桥塞封层工艺1-销钉;2-锁环;3-上压外套;4卡瓦;5上坐封剪钉;6-保护伞;7-桥塞-桥塞封层工艺封隔件;8-中心管;9-锥体;10-下坐封剪钉该桥塞具有以下特点:①结构简单,下放速度快,可用于电缆、机械或者液压坐封。

公司备有各种工具的详细资料,欢迎您来电来函咨询。

工作原理四机赛瓦公司生产的“MWBR”电缆坐封可取式桥塞是一种封隔器型桥塞,可用电缆压力或液压座封工具坐封,用油管、钢丝绳、连续油管上提回收。

这种桥塞可用于封隔层间、油井增产或井口维修(测试、压裂和修井)等措施下。

工具坐封完成后,可以有效封隔层位,此时可从井中下入或起出其它施工工具,从而省去了压井的需要。

该桥塞的特点是将回收颈和平衡阀组合在一个多元封隔系统上,在桥塞下部装有锁环制动装置。

位于多元封隔系统下的卡瓦在牢牢地将桥塞锚定在套管上后,可以承受较大的上下压力。

并且该桥塞的坐封过程也比较简单方便,只需将电缆或液压座封工具与桥塞联接在一起后,一同送入井下预定坐封位置,点火或打压上提油管即可实现丢手。

5 1/2”桥塞释放力为:30,000 LBS(13.6吨),7”桥塞释放力为:55,000 LBS(25吨)。

“MWBR” 桥塞的特点:●结构简单、易下,电缆坐封或液压坐封;●能可靠的坐封在包括P-110以内的套管中;●推荐适用温度150℃(300℉),压力70Mpa(10,000PSI)的工况;●棘齿锁环保持坐封负荷,保证在压力变化下仍能可靠密封;●可用现行通用的电缆坐封工具或液压坐封工具坐封(如MAP、GO、BACKER、GEARHAT)。

桥塞可按下列程序回收:a)回收工具套锁到桥塞回收颈上;b)上提工具打开平衡阀,平衡桥塞处压力;c)下放工具(桥塞不动);d)上提解封,回收。

“MWBR”电缆坐封回收式桥塞回收步骤:回收桥塞之前应反循环冲砂,以便使回收工具顺利套锁在打捞颈上。

用油管回收回收“MWBR”电缆可取式桥塞按照如下四步骤进行:1.下放回收工具:当回收工具下至桥塞打捞颈部为时,慢慢下放,并在桥塞上施加2吨左右的压力,让其全部套入桥塞打捞颈中。

电缆泵送复合桥塞

电缆泵送复合桥塞

电缆泵送Magnum复合桥塞以下所描述的工艺操作流程对于泵送与起出Magnum复合桥塞并不是固定不变的,每一步操作都需要根据井况进行调整。

该通用流程只能辅助解决有可能遇到的问题。

该操作流程不适用于Magnum永久式复合桥塞。

桥塞入井前,必须通过通井规、刮管器或者模拟桥塞通井。

通井规,刮管器或者模拟桥塞的外径必须大于桥塞的外径。

直井入井前:记录套管接箍定位器到复合桥塞底部的距离等相关需要测量的数据。

推荐起出防喷管中的钻具组合,如果不行的话,再使用推管车,但是推管车不能用于支撑钻具组合的重量。

一旦钻具组合被悬挂起来,必须采取预防措施防止桥塞碰到会对桥塞或人员引起伤害的障碍物。

校深时如不能将工具串置于地面,则用鼠洞或者井口。

记录钻具组合管串的重量。

注意:对防喷管试压时,应缓慢增加和降低压力,否则会伤害复合桥塞。

在打开井眼前确保井眼压力与防喷器缓慢平衡。

当通过井口装置下放钻具组合时,应格外小心,避免损坏复合桥塞。

入井:当接近液面时,推荐100f/min(30m/min)或更小的速度,记录液面位置。

注意:大于100f/min(30m/min)时,有可能引起桥塞提前坐封。

钻具组合泵入速度控制在250f/min(75m/min)以下,泵入位置超出坐封深度后停泵。

在起出工具之前测量井底钻具组合悬重。

校深后,将工具串提到桥塞坐封位置。

将一旦桥塞到位,点火坐封,在起出坐封工具前等待大概两分钟以确保桥塞与坐封工具已剪断、分离。

在起出坐封工具时要监测管串重量。

管串重量被提起后,如果下入的是死堵桥塞或单流阀式桥塞可进行试压对。

不要返回下探桥塞!继续上提电缆,监测重量,校深到达射孔位置后射孔。

各簇射孔全部完成后,上提起出电缆,射孔枪起到液面位置前,速度降至100f/min(30m/min)。

超过液面位置后以合适且安全的速度将工具取出。

将球置于井口,平衡井筒压力。

注意:如井筒压力未达到平衡,球有可能撞击压裂井口顶部压帽被打碎。

MWBR可取式桥塞说明书

MWBR可取式桥塞说明书

下井
将坐封工具与桥塞正确连接,采用油管传输把封隔器下到要求的坐封深度,下放速度不宜超过40柱/小时,注意控制下钻速度,严禁顿钻、溜钻,工具与液面接触时,应匀速缓下,过造斜点、套管悬挂、套变时也要匀速缓下。

在下井过程中,如果遇阻,应立即停止,再通过缓慢上提下放动作来活动管柱,注意遇阻力不能超过5吨。

如果尝试几次仍无法下入,取出管柱,分析原因。

坐封
投球:一般采用自由落体到位,(直井不允许泵送),当井底压力大时,可采用小排保
循环送球到位;如果是水平井作业,投球后5min即可大排痲泵送。

连接地面打压管线,准备打压工作;
打压座封:分段缓慢打压至lOMPa、15MPa、20MPa各稳压5min,此过程使橡胶
套充分膨胀、卡瓦完全咬死在套管上,当压力泄为零时说明工具已丢手坐封。

51/2 桥塞坐封压力为20-24Mpa。

验封:按照施工设计,套管打压验封
意外情况处理
以下情况可能会造成桥塞正常座封但不能正常丢手:
1,座封工具内密封件磨损破坏,导致座封后打压时漏压,活塞不能产生足够推力导致释放栓不能正常打断;
2,由千油管内杂质较多,工具入井过程中,脏物下沉至坐封工具球座及上压缩杆内,堵死压缩杆,下缸不能正常工作,不能产生足够推力,释放栓不能正常打断
此时需持续打压超出最高释放压力lOMPa,若仍未打断,可以采取油管正打压+上提管柱的方法丢手:。

MWBR可取式桥塞说明书

MWBR可取式桥塞说明书

MWBR 可取式桥塞使用说明书四机赛瓦公司生产的“MWBR”电缆坐封可取式桥塞是一种封隔器型桥塞,可用电缆压力或液压座封工具坐封,用油管、钢丝绳、连续油管上提回收。

这种桥塞可用于封隔层间、油井增产或井口维修(测试、压裂和修井)等措施下。

工具坐封完成后,可以有效封隔层位,此时可从井中下入或起出其它施工工具,从而省去了压井的需要。

该桥塞的特点是将回收颈和平衡阀组合在一个多元封隔系统上,在桥塞下部装有锁环制动装置。

位于多元封隔系统下的卡瓦在牢牢地将桥塞锚定在套管上后,可以承受较大的上下压力。

并且该桥塞的坐封过程也比较简单方便,只需将电缆或液压座封工具与桥塞联接在一起后,一同送入井下预定坐封位置,点火或打压上提油管即可实现丢手。

5 1/2”桥塞释放力为:30,000 LBS(13.6吨),7”桥塞释放力为:55,000 LBS(25吨)。

产品结构、特点●结构简单、易下,电缆坐封或液压坐封;●能可靠的坐封在包括P-110以内的套管中;●推荐适用温度不高于150℃(300℉),压力不高于70Mpa(10,000PSI)的工况;●棘齿锁环保持坐封负荷,保证在压力变化下仍能可靠密封;●可用现行通用的电缆坐封工具或液压坐封工具坐封(如MAP、GO、BACKER、GEARHAT)。

下井前准备工作●检查桥塞型号是否与施工的井况相符●检查密封胶套是否有起泡、裂纹等缺陷和是否在保质期内,如果有上述缺陷或已过保质期,必须更换所有密封件●采取必要的措施保证坐封段井壁干净无垢●用适当规格的通井规通井,以保证可以正常下入工具将坐封工具与桥塞正确连接,采用油管传输把封隔器下到要求的坐封深度,下放速度不宜超过40柱/小时,注意控制下钻速度,严禁顿钻、溜钻,工具与液面接触时,应匀速缓下,过造斜点、套管悬挂、套变时也要匀速缓下。

在下井过程中,如果遇阻,应立即停止,再通过缓慢上提下放动作来活动管柱,注意遇阻力不能超过5吨。

如果尝试几次仍无法下入,取出管柱,分析原因。

使用说明书
(中美合资)四机赛瓦石油钻采设备有限公司生产的 "MWB"型桥塞是结构紧凑,外表面平滑的桥塞,适用于多种规格的套管。

这种桥塞与其它类型的桥塞相比有直径小、中心管短的特点,因此下放就比较快且简单。

整体式卡瓦避免中途坐封且易钻除。

平滑的金属背圈结构、单胶筒和棘轮锁环在套管和密封件之间组成可靠的密封系统。

在进行射孔作业之前,必须在桥塞上堆积砂子或水泥来给予其充分的保护,这样就可防止对桥塞的冲击破坏。

●结构简单、易下、电缆坐封或液压坐封;
●能可靠的坐封在任何级别(包括P-110)的套管;
●棘轮锁环保持坐封负荷,保证压力变化下仍可靠密
封;
●单胶筒和平滑的金属背圈组成可靠的密封系统;
●整体式卡瓦避免中途坐封且易于钻除;
●推荐用于温度177°C(350°F)、压力70Mpa
(10,000PSI)的工况;
●铸铁结构容易钻除;
●可直接用各种BAKER,GEARHAT,
HALLIBURTON 电缆坐封工具或液压坐封工具坐封。

操作指导
与坐封工具的连接:
1)将BAKER接头包中的调整接头接到BAKER或GEARHAT的电缆或液压坐封工具底部的活塞杆上,用扳手拧紧,并拧紧顶丝;
2)将接头包中的坐封套接到BAKER或GEARHAT的电缆或液压坐封工具上,用扳手拧紧;
3)将锁紧弹簧卡在调整接头下端的缺口内,再将桥塞上的释放栓穿过锁紧弹簧而与调整接头相连,将扳手打在桥塞的套阀上,顺时针旋转桥塞,直到坐封套抵住桥塞上端的背圈,至此连接完成
坐封过程:
" MWB桥塞可按与常规可钻式封隔器或桥塞一样的方法下到要求的坐封深度,桥塞组件的剪切销的设计是作为防止特殊井况引起提前坐封的安全方法。

在下桥塞的过程中,最佳的下放速度为100英尺/分钟(30米/分钟),在坐封过程中,坐封套抵住桥塞外部各组件,而拉杆则提拉桥塞中心管,这个动作使卡瓦坐住,橡胶套胀大,桥塞被压缩坐封,给释放栓加一定的拉力,释放栓被拉断,坐封工具和接头包就可以从井中取出.
桥塞坐封后,将坐封工具提高几英尺,然后缓慢放回,以确定桥塞是否坐封在正确的位置上。

在坐封过程中,指重表可能会有两次跳动,一次跳动是指剪切销被剪断,另一次跳动是指释放栓被拉断。

注意:在桥塞上作业前,须将3米高的沙或水泥堆积在坐封的桥塞上,这样作业的安全就可得到保证,同时能防止震动带来的对桥塞的损坏。

参照下表中的拉力(除去油管净重),即可坐封桥塞
在尽可能的情况下推荐使用上表中的最大拉力,无论在何种情况下,为了确保胶套的充分压缩以及卡瓦的破裂,实际操作中的拉力至少等于上表中的最小拉力。

钻除时的推荐参数、推荐下面成功的钻除水泥承留器所使用的技术参数 :
1. 钻头-------------------------新的,短齿,中等硬度;
2. 转速-------------------------一般为80转/分(如果需要可达120转/分);
3. 钻头上施加的力---------------施加5000到7000磅,直到桥塞中心管外径上端被钻掉(4 1/2"-7"规格的桥塞大约7英寸,180毫米,7 5/8"以及更大规格的桥塞约10英寸,254毫米)之后,可增加重量到钻头上。

增加重量为:钻头直径每英寸为2000到3000磅(例如:钻头直径为4 3/4英寸,则使用12000到14500磅的力量)。

4. 钻铤---------------------------最少8只(4 1/2"和5 1/2")最少12只(7"和更大规格)间断转动钻杆,变化钻杆钻速和施加重量,有利于破坏大块金属和阻止钻头卡钻。

当正常循环时,可在钻头上使用一个或多个落物篮。

1.1.1 拆卸工具各部分(管钳打在非密封面处),清洗各零件
1.1.2 检查零件上的孔、通道,要保持畅通
1.1.3 “O”形圈处涂黄油,螺纹处涂螺纹保护脂
1.1.4 按装配顺序装配,各零件用管钳打紧(管钳打在非密封面处)
1.2 采取必要的措施(套铣、刮削、洗井)保证坐封层位±5m段套管内壁干净、无

1.3 用标准通井规通井
1.4 检查桥塞的上下卡瓦有无裂纹、牙形是否良好,橡胶套表面有无刮伤
1.5 按照使用说明书连接坐封工具和桥塞,要求上卡瓦可径向转动,而轴向无位移;
同时,运输过程中要保护好工具,特别是卡瓦和橡胶套
1.6 检查管柱的密封性能、强度及内径,保证钢球能顺利通过(条件允许时,可采用
新油管)
2.施工过程
2.1下管柱:限速下钻(40-50根/小时),下钻应匀速、平稳,禁止猛停猛放,顿
钻、溜钻,同时要事先判断井内液面的位置,工具与液面接触时,应匀速缓
下,过造斜点、套管悬挂、套变时也要匀速缓下。

2.2 投球:一般采用自由落体到位,(直井不允许泵送),当井底压力大时,可采用
小排量循环送球到位;如果是水平井作业,投球后5min即可大排量泵送。

2.3 坐封:打压时,压力每升高5Mpa,稳压3-5min,当压力达到15Mpa时(4 1/2”-
6 5/8”的桥塞,理论值16Mpa丢手,7”-13 5/8”的桥塞,理论值27Mpa丢手),
可采用下列方法丢手:
2.3.1 缓慢打压直至丢手。

2.3.2缓慢上提管柱直至丢手,推荐使用此方法,上提与打压配合关系见附表。

2.4 探塞:加钻压不得超过5吨,下探桥塞是否下移(过大的钻压可能损坏桥塞)
2.5 验封:各施工单位可以根据自己的施工要求进行验封。

2.6 起管柱,坐封工具取出后及时保养
附表上提与打压配合表。
