摘要： A method and apparatus to affix a tool downhole in a cased wellbore, one embodiment comprising a tubular body with a slot along its length. A portion of the slot is V-shaped to accommodate a wedge with a corresponding V-shape. The outside of the tubular body has integral teeth. To set the apparatus, the wedge is driven into the V-shaped slot. This movement widens the slot and expands the diameter of the tubular body until it intersects with the casing. The teeth on the outside of the body bite into the casing wall to affix the tool to the casing.

摘要： The reference member provides a permanent reference for the depth and orientation of all well operations and includes a body with an engaging surface for an attaching engagement to the interior surface of an existing casing in a borehole and an orienting surface for orienting well tools within the cased borehole. No sealing engagement is required with the casing. The engaging surface on the body has a first non-engaged position where the engaging surface does not engage the casing and an engaged position where the engaging surface does engage the casing which causes adequate engagement between the body and the casing to permanently dispose the well reference member within the casing. The well reference member further includes an actuation member for actuating the engaging surface from the non-engaged position to the engaged position. The actuation member may be an expansion member which expands the body having an engaging surface into engagement with the casing or which expands engaging surfaces, reciprocably mounted on the body, into engagement with the casing.

摘要： The well reference apparatus and method of the present invention includes a reference member preferably permanently installed within the borehole at a preferred depth and orientation in one trip into the well. The reference member provides a permanent reference for the location of all operations, particularly in a multi-lateral well. The assembly of the present invention includes disposing the reference member on the end of a pipe string. An orienting tool such as an MWD collar is disposed in the pipe string above the reference member. This assembly is lowered into the borehole on the pipe string. Once the preferred depth is attained, the MWD is activated to determine the orientation of the reference member. If the reference member is not oriented in the preferred direction, the pipe string is rotated to align the reference member in the preferred direction. This process is repeated for further corrective action and to verify the proper orientation of the reference member. Upon achieving the proper orientation of the reference member, the reference member is set within the borehole and the pipe string is disconnected from the reference member and retrieved.

摘要翻译：本发明的参考装置和方法包括一个参考构件，优选地以一个行程进入井中的优选的深度和取向永久地安装在钻孔内。参考构件为所有操作的位置提供永久参考，特别是在多侧井中。本发明的组件包括将参考构件设置在管柱的端部上。诸如MWD轴环的定向工具设置在参考构件上方的管柱中。该组件下降到管柱上的钻孔中。一旦获得了优选的深度，则MWD被激活以确定参考构件的取向。如果参考构件不是在优选方向上定向，则管柱旋转以使参考构件沿优选方向对齐。重复此过程以进一步的纠正措施并验证参考构件的正确定向。在实现参考构件的正确取向时，将参考构件设置在钻孔内，并且将管柱与参考构件断开并取出。

摘要： A downhole tool includes a pressure activated flow switch for selectively actuating and deactuating a device, such as a reaming block. The flow switch is deployed external to the flow bore and includes a flow piston configured to reciprocate between axially opposed open and closed positions such that the device is actuated when the flow piston is in the open position and deactuated when the flow piston is in the closed position. The flow piston is configured to translate from the closed position to the open position when a differential pressure exceeds a predetermined threshold. The flow piston may be further configured to remain in the open position at differential pressures less than the threshold.
