这套卡瓦用于带压起下管柱时, 在重管柱模式下卡紧管柱.
They also hold the string during connections when in stripping mode while using the workover rig drawworks. They are attached to the top of the rotary on the rig assist unit
Proprietary
在不压井作业过程中,这套卡瓦用于轻 管柱模式下卡紧管柱，他们倒置装配, 以保证在管柱轻时阻止管柱从井筒中 被顶出。它们位于作业机被动转盘的 底部，当活塞杆液缸来回移动时，上 下移动。

JACK PLATE 活塞杆连接板
This plate, made of high strength steel, physically ties the two hydraulic cylinders together. It is designed for quick removal to facilitate wire line operations, and access to BOP's contained within the structure of the unit. Built into the plate is the passive or powered rotary and traveling slip attachment points.

HYDRAULIC CYLINDERS 液缸
These cylinders provide the necessary force to jack the pipe into and out of the hole during snubbing operations. The bore and ratio of these cylinders dictates the maximum force that the snubbing unit can exert. The force applied by these cylinders can be infinitely controlled by the units hydraulic system

STATIONARY HEAVY SNUBBING SLIPS 固定承重卡瓦
On units equipped with four sets of slips, these slips hold the pipe from falling down the hole during stripping operations. This set of slips gives the snubbing unit ability to provide pipe movement when in heavy mode independent from the rig draw works.
在起下过程使用修井车绞车甩/接 单根时,它也会卡紧管柱. 它位于 作业机被动转盘的上部.
Rig Assist Components
TRAVELLING SNUBBING SLIPS 游动下压卡瓦
This set of slips grip the pipe during snubbing operations. They are mounted in an inverted position to prevent the pipe from being ejected from the well bore while in pipe light mode. They are attached to the bottom of the rotary on the unit and travel up and down as the jack hydraulic cylinders are reciprocated.

上闸板防喷器是一个单闸板防喷器，安装在设备 内部、环形防喷器的正下方。防喷器组设计坚固 ，耐磨. 与环形防喷器不同,闸板防喷器只密封一 个特定尺寸的管柱外径, 这个尺寸取决于作业前 的选择. 闸板防喷器采用很强健的设计, 当环形 防喷器不能安全承受井内压力时，操作手可选择 上闸板防喷器协助控制井内压力。 大部分架助式 不压井作业机采用7.062”, 5000psi的标配。
Proprietary
被动转盘允许管柱在管柱轻的状 态时进行旋转，以实现在管柱轻 的状态时人工旋转井下工具，或 者与动力水龙头配合进行钻进/磨 铣作业。
Rig Assist Components
STATIONARY SNUBBING SLIPS 固定下压卡
This set of slips holds the pipe from ejecting from the well during snubbing operations. They are engaged in order to release the traveling slips and allow the jack to be stroked for the next bite. These slips are mounted in a fixed position in the slip window or slip shoe above the annular preventer. 在不压井作业过程中，该套卡瓦用于卡紧 管柱，防止管柱被顶出。当移动下压卡瓦 松开管柱时，该卡瓦卡紧管柱，使得移动 下压卡瓦可以上移一个冲程再次卡紧管柱 。该套卡瓦安装于环形防喷器上部卡瓦窗 口的固定位置或者卡鞋位于环防上方。
Proprietary
不压井作业时，液缸提供将管柱下入 和提出井眼所需的力。液缸口径决定 了不压井设备所能施加的最大力。设 备液压系统可以无限控制液缸施加的 力。

PASSIVE ROTARY OPTION 被动转盘
This allows the rotation of the string in the pipe light mode. It gives the unit the ability to set tools requiring rotation manually while in the pipe light mode, or to perform drilling/milling operations in snub mode when coupled with a power swivel
Proprietary
固定承重卡瓦每套有四组卡瓦, 他 们用于带压起管柱时卡紧管柱，防 止管柱落入井中。在重管柱状态时 ，该套卡瓦使不压井作业装置不用 作业机绞车也能移动管柱。

ANNULAR PREVENTER 环形防喷器
This BOP provides the primary seal on the outside of the pipe during tripping operations. It incorporates a flexible elastomer element that can conform to virtually any shape including open hole in an emergency situation. The hydraulic system that operates this preventer is designed to allow very quick reaction times to changes in the pipe’s outer diameter, such as tool joints or collars. Although the hydraulic system has this ability, there are limits that the element can react too such as very large outer diameter (OD) changes or higher pressures. When these situations arise, it is necessary to incorporate the stripping rams mounted below the annular. This BOP has a pressure rating of 5000 psi (35 Mpa), and has a through bore of 7.062” (179 mm)

Traveling Heavy Slips 游动承重卡瓦
This set of slips is utilized during stripping operations, to hold the pipe in heavy mode during the transition from pipe light to pipe heavy.

TOP STRIPPING RAMS 上闸板防喷器
This is a single gate BOP that is mounted within the structure of the unit directly below the annular preventer. The BOP is typically dressed with a special style of ram front that has very good wear characteristics. Unlike the annular preventer, the stripping rams will only seal on a specific size of pipe OD depending upon what the crew has dressed them for. These BOP's are of a very robust design, and in situations where the annular preventer is unable to safely contain the well pressure, the stripping rams provide the operator options for well control. 7.062” (179 mm) by 5000 psi (35 Mpa) is standard on most rig assist units.

带压起下作业时，环形防喷器对作业管柱外径提 供主密封。它使用了一个柔性合成橡胶胶芯，适 用于任何形状的井眼，包括紧急状况下的空井。 操作该防喷器的液压系统设计成能够快速应对管 柱的外径变化，如工具接头或接箍。尽管液压系 统有这个能力, 但是当外径变化较大或压力较高 时, 胶塞的控制能力是有极限的，这种情况发生 时，需联合环防下方的闸板防喷器一起控制。该 防喷器额定压力为5000 psi, 通径为7.062”.
