摘要： A mechanical set anchor wherein a plunger extending from a base end of an anchor body activates a pin type trigger which releases a spring utilized to set multiple slips extending from the body of the anchor. Continued downward compressive forces fully sets the slips into the borehole pipe casing. The slips are maintained in their fully set position by a locking nut. The anchor is mechanically released by an upward pull under tension of sufficient strength to shear release pins that release the compressed spring fully retracting the slips within the anchor body so that the anchor may be tripped from the borehole without interference from the previously engaged slips.

摘要： A two trip sidetrack casing milling apparatus for elongating and enlarging a previously formed window in a cased borehole in preparation for a subsequent sidetracking drilling operation is disclosed. The apparatus consists of three mills on a shaft, a first window mill is secured to an end of a shaft. The first window mill forms a diameter larger than a diameter of a subsequent sidetracking drill bit that is passed through the window. A second pilot mill is secured to the shaft and strategically positioned above the first window mill. The second pilot mill forms a diameter that is less than the diameter of the first window mill. A third watermelon mill is secured to the shaft and strategically positioned above the second pilot mill. The third watermelon mill forms a diameter that is at least the same diameter as the first window mill. The second, smaller in diameter pilot mill serves to move toward the window thereby straightening the shaft while further cutting a portion of the casing surrounding the window thus assuring a more stable and accurate sidetrack direction. The third watermelon mill serves to dregs the window in the casing after the first window mill and the second pilot mill pass through the casing.

摘要： A wellhead severing system for detonating a liquid explosive charge and subsequent removal of the wellhead from the sea floor. The explosive severing system includes a charge container holding a liquid explosive and a contractable bladder in fluid communication with the charge container to compensate for pressure and temperature variations as the system is lowered to the wellhead in the sea floor. Liquid explosive from the bladder flows into the charge container maintaining a constant volume of uncontaminated explosive around the detonators. The severing system is lowered into the wellhead on a running string and detonated through high voltage wires extending to a connector or the surface.

摘要： A starter mill adapted for use with a whipstock to mill a window through the casing of a well for deviating the direction of drilling. The starter mill includes a bearing nose which is utilized to indicate completion of the milling process. As the mill nears completion of the milling process, the bearing nose will become wedged between the whipstock face and the casing preventing further downhole movement. The bearing nose will engage whipstock and casing, allowing the work string to continue to rotate although the decreased torque resulting from the absence of milling provides a clear signal that the milling operation is complete. The cutters of the mill are spaced a predetermined distance from the bearing nose to ensure completion of the casing window.
摘要翻译： 一种起动机，适于与造斜器一起使用，以便通过井的外壳铣削窗口，以偏离钻孔方向。 起动机包括用于指示铣削过程完成的轴承端头。 随着铣床接近完成铣削过程，轴承的鼻子将楔入到造斜器面和套管之间，防止进一步的井下移动。 轴承端头将接合造斜器和外壳，允许工作线继续旋转，尽管由于没有铣削而产生的扭矩减小提供了铣削操作完成的清晰信号。 铣刀的切割器与轴承鼻部间隔预定距离，以确保壳体窗口的完成。

摘要： A detonation assembly for an explosive wellhead severing system which employs a battery pack lowerable through a drill string to engage and power the detonation assembly positioned within the well bore. The lowerable unit includes a biased shutter which seals the contacts from discharge of the battery pack by the surrounding fluids. The shuttered unit is lowered into contact with the receiving unit to arm the detonation assembly. Until the power unit is lowered into engagement, the severing system is not armed. In case of malfunction or misfire, the power unit can be retrieved to disarm the detonator assembly. The entire assembly is housed within the drill string to isolate the critical elements from the surrounding environment.
