摘要： This disclosure is directed to a connector apparatus for a semi-flexible tubing. The connector apparatus includes an inner sub having a first end disposable within a semi-flexible tubing and a second end connectable to various other downhole tools. The first end of the inner sub includes at least one depression disposed thereon that is generally alignable with at least one depression disposed on the semi-flexible tubing. The connector apparatus also includes an external sleeve disposable outside of the semi-flexible tubing. The external sleeve having at least one opening disposed therein generally aligned with the at least one depression in the first end of the inner sub. This disclosure is also directed to a method of installing the connector apparatus on a semi-flexible tubing and a method of running the semi-flexible tubing and a downhole tool into a wellbore via the connector apparatus disclosed herein.

IPC分类号： E21B4/02
摘要： A rotary actuator assembly can include a fluid motor with a rotor that displaces with hypocyclic precessional motion within a stator in response to fluid flow through the fluid motor, and a gear reducer section including an input gear that is fixed relative to the rotor and displaces with the hypocyclic precessional motion relative to an output gear. Another rotary actuator assembly can include a fluid motor with a rotor having a central longitudinal axis that rotates about a central longitudinal axis of a stator, and a gear reducer section including an input gear that rotates with the rotor and displaces relative to an output gear, and the input gear having the same central longitudinal axis as the rotor. A well system can include at least two fluid motors, and fluid flow through one fluid motor causes rotation of the other fluid motor in the well.

摘要： A sleeve shifting tool for shifting a slidable sleeve positioned inside of another dowhole tool is described herein. The tool has a housing and a collet apparatus for engaging a slidable sleeve disposed within a downhole tool positioned in a wellbore. The collet apparatus includes at least one collet arm and at least one collet key disposed thereon for engaging the slidable sleeve. The tool also includes a collet activation apparatus for initiating the collet apparatus and force the at least one collet key of the collet apparatus to engage the slidable sleeve. A method of shifting a sleeve positioned in a downhole tool with the sleeve shifting tool described herein is also provided herein.
摘要翻译：这里描述了用于移动位于另一个钻孔工具内部的可滑动套筒的套筒移位工具。该工具具有壳体和夹头装置，用于接合设置在定位在井眼中的井下工具内的可滑动套筒。夹头装置包括至少一个夹头臂和设置在其上的用于接合可滑动套筒的至少一个夹头键。该工具还包括用于启动夹头装置并迫使夹头装置的至少一个夹头键接合可滑动套筒的夹头启动装置。本文还提供了使用本文所述的套筒移位工具来移动定位在井下工具中的套筒的方法。

摘要： A tubular string for use in a well can include a fluid motor and a tractor tool. The fluid motor can rotate the tractor tool in response to fluid flow through the fluid motor. Another tubular string can include a fluid motor, a gear reducer that reduces a rotational speed output of the fluid motor, and a tractor tool. The fluid motor and the gear reducer can rotate the tractor tool in response to fluid flow. Another tubular string can include a fluid motor, a tractor tool, and another fluid motor. One of the fluid motors can rotate with the tractor tool. A system for use in a subterranean wellbore can include a tool assembly. The tool assembly can include a fluid motor and a tractor tool. The tractor tool can be configured to engage a well surface in the wellbore and advance the tool assembly along the wellbore.
