摘要： A method and apparatus for delivering repetitive jarring impacts to a stuck object downhole. The jarring tool is deployed on coiled tubing or other tubular well conduit, and fluid pressure is used to cycle the jar without reciprocating the well conduit at the wellhead. The tool includes a hydraulic reset assembly. The hydraulic chamber is in fluid communication with the flow path through the tool. Thus, when the internal fluid pressure inside the tool exceeds the external pressure in the well, the fluid pressure drives the piston in the hydraulic chamber to urge the tool toward the contracted position. In this way, the reset assembly can overcome the tendency of fluid pressure to extend the tool. The reset assembly can be configured to balance or equalize the extension pressure, to prevent undesired cocking of the tool, or to overcome the extension pressure to contract the tool for recocking the jar mechanism.
摘要翻译：一种用于向井下的被卡住的物体传送重复的振动冲击的方法和装置。刺耳工具部署在连续油管或其他管状井管道上，并且使用流体压力来循环罐，而不会在井口往复运动。该工具包括液压复位组件。液压室与通过工具的流动路径流体连通。因此，当工具内的内部流体压力超过井内的外部压力时，流体压力驱动液压室中的活塞以将工具推向收缩位置。以这种方式，复位组件可以克服流体压力延伸工具的倾向。复位组件可以被配置为平衡或均衡延伸压力，以防止工具的不期望的起动，或者克服延伸压力以收缩工具以重新装回罐机构。

摘要： A vortex-controlled variable flow resistance device ideal for use in a backpressure tool for advancing the drill string in extended reach downhole operations. The characteristics of the pressure waves generated by the device are controlled by the growth and decay of vortices in the vortex chamber(s) of a flow path. The flow path is designed to produce alternating primary and secondary vortices -- one clockwise and one counter-clockwise - where the primary vortex is stronger and produces higher backpressure than the secondary vortex. This in turn generates alternating weak and strong pressure pulses in the drill string. The weak pulses may be barely perceptible so that the effective frequency of the pulses is determined by the stronger primary vortices.
摘要翻译：一种涡流控制的可变流阻电阻装置，理想用于背压工具，用于在延伸到井下作业中推进钻柱。由装置产生的压力波的特性由流路的涡流室中的涡流的增长和衰减来控制。流道被设计成产生交替的主涡流和次涡流 - 一个顺时针和一个逆时针旋转，其中主涡流更强并且产生比次涡流更高的背压。这又在钻柱中产生交替的弱和强的压力脉冲。弱脉冲可能几乎不可察觉，使得脉冲的有效频率由较强的主旋涡确定。

摘要： A casing string is augmented with one or more variable flow resistance devices or "vibrating tools" to facilitate advancement of the casing and distribution of the cement in the annulus once the casing is properly positioned. The method includes vibrating the casing string while advancing the casing down the wellbore or while the cement is pumped into the annulus, or both. After the cementing operation is completed, the devices may be drilled out to open the casing string for further operations. The casing string assembly may include a vibrating tool at the end in place of a conventional float shoe or float collar. Multiple vibrating tools can be employed in the casing string, and they may be combined with conventional float shoes and collars. Additionally, vibrating tools in the form of plugs can be pumped down and landed inside the casing string.

摘要： A system can include a disconnect tool connected as part of a tubular string, the disconnect tool including an outer housing, and an inner mandrel in the outer housing, in which an abrasive slurry is directed to flow through the tubular string and from the inner mandrel to an annulus between the inner mandrel and the outer housing, and the abrasive slurry erodes through the outer housing. A method can include installing a tubular string in a well, then deploying a disconnect assembly into the tubular string, and flowing an abrasive slurry through the disconnect assembly, thereby parting the tubular string. A disconnect tool can include a rotational flow structure configured to induce rotational flow, and an inner diameter decrease downstream of the rotational flow structure.

摘要： A motor and rotor catch assembly for preventing loss of broken motor parts downhole. The assembly comprises a motor including a rotor supported inside a stator housing. A rotor bolt is connected to the upper end of the rotor, and is supported for axial movement within a rotor bolt housing from a running position to a deployed position. If the stator housing breaks or backs off, the attached rotor bolt shifts to the deployed position. In the deployed position, the bolt substantially reduces flow to the stator housing and simultaneously opens bypass ports to vent fluid to the annulus instead. In this way, the rotor is prevented from spinning rapidly, the diverted fluid creates a pressure change that alerts the operator to the motor failure, and the diverted fluid allows continued removal of debris and cuttings from the well bore.
