Abstract: A one trip system for expanding a tubular that is solid or perforated or a screen comprises a downhole assembly that features a hydraulic anchor that can be set, released and repositioned to repeat the process. The anchor is small enough to go through the tubular or screen after initial expansion. The anchor's maximum extension is designed to avoid overstressing the already expanded tubular or screen. An expansion tool is hydraulically driven with the initial portion of the stroke delivering an enhanced force. The expansion tool initially supports the tubular or liner but subsequently releases during the first stroke, after the tubular or screen is fully supported.
Abstract translation: 用于膨胀固体或穿孔的管状物或筛网的单行程系统包括井下组件，其特征在于可以设置，释放和重新定位以重复该过程的液压锚杆。 初始膨胀后，锚杆足够小以穿过管状或屏幕。 锚杆的最大伸长距离设计用于避免已经膨胀的管状或屏幕过度应力。 膨胀工具由液压驱动，初始部分的行程提供增强的力。 膨胀工具最初支撑管状或衬管，但随后在管状或筛网被完全支撑后在第一次冲程期间释放。

Abstract: A method of repairing tubulars downhole is described. A swage is secured to a force magnification tool, which is, in turn, supported by an anchor tool. Applied pressure sets the anchor when the swage is properly positioned. The force magnification tool strokes the swage through the collapsed section. The anchor can be released and weight set down on the swage to permit multiple stroking to get through the collapsed area. The swage diameter can be varied.

Abstract: A ball release mechanism is mounted near the intended seat. The ball or balls are kept out of the circulating stream. High circulation rates followed by curtailment of circulation places an outlet port in position to allow the ball or balls to be pushed out by a spring. The spring or one of the balls prevents the return of an ejected ball back into the protected pocket. The ball is delivered to the seat without circulation.
Abstract translation: 球释放机构安装在预期座位附近。 球或球保持在循环流中。 高循环率随之而来的流通量减少了出口口，使球或球被弹簧推出。 弹簧或其中一个球防止弹出的球返回受保护的口袋。 球被送到座位而不循环。

CPC classification number: E21B31/005
Abstract: A downhole vibration tool consisting of a body assembly installed in a work string, and a drop-in dart valve assembly. An open inner bore through the body assembly allows the performance of operations through the body assembly. To activate the vibration tool, the dart valve assembly is dropped into the work string and pumped downhole into engagement with the body assembly. Once the dart valve assembly is in place in the body assembly, continued pumping of fluid will cause the tool to begin to vibrate longitudinally. When the jarring operation is finished, the dart valve assembly can be released from the body assembly and retrieved, with a wireline or coiled tubing unit.
Abstract translation: 由安装在工作串中的主体组件和落入落料阀组件组成的井下振动工具。 穿过主体组件的开放的内孔允许通过主体组件执行操作。 为了激活振动工具，飞镖阀组件落入工作串并被泵入井下与主体组件接合。 一旦喷嘴阀组件就位于主体组件中，则持续泵送流体将导致工具纵向开始振动。 当敲击操作完成时，飞镖阀组件可以从主体组件释放，并用电缆或连续油管单元取回。

Abstract: A tool for cutting or milling casing in a well is disclosed. It includes a plurality of blades extending outwardly to a substantially radial position for cutting the walls of casing strings and removing a predetermined length of the casing strings in a cutting action. The blades have cutting elements positioned on leading faces of the blades to engage the casing strings in a cutting action without tripping or removal from the bore hole. The cutting elements can be arranged in rows and columns. The cutting elements can be shaped to continually present a sharp cutting edge to the object being milled. The cutting elements can be inclined at a negative axial rake angle to cause the metal chips cut from the object being milled to break off at short lengths. The cutting element can also have surface irregularities to cause the metal chips cut from the casings to break off at short lengths. The cutting element can also have stress relieving grooves to prevent the propagation of a crack across the face of the element.
Abstract translation: 公开了一种用于在井中切割或铣削套管的工具。 它包括多个叶片，其向外延伸到基本上径向的位置，用于切割套管柱的壁并在切割动作中移除预定长度的套管柱。 叶片具有定位在叶片的前表面上的切割元件，以切割动作使套管柱接合，而不会从钻孔中脱落或移除。 切割元件可以排列成行和列。 切割元件可以被成形为连续地向被研磨的物体呈现锋利的切割边缘。 切割元件可以以负轴向前角倾斜以使得从被研磨的物体切割的金属屑以短的长度断裂。 切割元件还可以具有表面不规则性，以使得从壳体切割的金属屑以短长度断开。 切割元件还可以具有减轻应力的凹槽，以防止裂纹在元件的表面上传播。

Abstract: This invention relates to a permanent whipstock assembly which uses camming pivot arms to secure the whipstock at the desired location within a cased wellbore. Camming pivot arms are pivotally attached to the downhole end of a whipstock housing and are further attached to a slip pad. Intentionally induced relative movement of the slip pad and the whipstock housing causes the camming pivot arms to pivot in such a manner that slip pad housing 4 and slip pad 5 are forced away from each other and cammed into the cased borehole. The invention relates specifically to a device that is particularly adapted to be lowered through a small diameter and later to be activated and set in a much larger casing or hole diameter.

Abstract: A cutting tool (10) for removing members downhole from a well bore and adapted to be inserted within a well from the upper end (12) of the casing (14). The cutting tool (10) includes a plurality of elongate blades (32) on the cylindrical body (18) of the cutting tool (10). Cutting elements (42) of a predetermined size and shape are arranged in a symmetrical predetermined pattern on each blade (32) in side-by-side relation in a plurality of predetermined transversely extending rows and a plurality of predetermined generally vertically extending columns. The cutting elements (42) in adjacent transverse rows for each blade (32) are staggered and have different concentric cutting paths. The cutting elements (42E) in corresponding transverse rows on adjacent blades (32A, 32B) are staggered and have different concentric cutting paths. The blades (32A, 32B) of the embodiment of FIGS. 7-13 have a separate recess (50) on the leading face (34A) for each individual cutting element (42E) for precisely positioning the cutting element (42E). Each cutting element (42E) has a groove (42K) for receiving and directing forwardly the extending end of a metal shaving (S) to facilitate breaking thereof from the casing (14).
