摘要： Tool and method to cut or perforate a pipe positioned partly or wholly inside another pipe and damage to the outer pipe must be avoided. Jet nozzles (124) are positioned at a non-normal angle to the target surface (102) to reduce the jets' effective cutting distance. While pumping the abrasive fluid, the jets are supported at a selected radial distance from the target surface (102) so that within a predetermined operating time the jets will cut or perforate the inner pipe but leave the outer pipe substantially intact. The tool may be rotated with a motor to perfonn cutoff operations or held in a fixed position for perforating.

摘要： A hydraulic jar for delivering impacts downhole. The jarring mechanism includes a cup-type piston that moves through a seal bore. The cup is deformable in response to fluid pressure so that it expands each time it moves through the seal bore to compensate for wear on the lip. Since only minimum interference is required between the piston and seal bore, less material may be used. This reduces the force required to reset the tool, which is particularly advantageous in horizontal wells. The seal bore may be slightly wider at the exit; the cup expands to this exit diameter, ensuring an interference fit as the cup travels back through the smaller diameter entry section. The entry end of the seal bore may include longitudinal grooves. This prevents the piston cup from rupturing by preventing a fluid seal around the lip until the most of cup is inside the seal bore.
摘要翻译：用于在井下输送冲击的液压罐。振动机构包括移动穿过密封孔的杯形活塞。杯子响应于流体压力而变形，使得其每次穿过密封孔时都会膨胀，以补偿唇缘上的磨损。由于在活塞和密封孔之间只需要最小的干扰，所以可以使用更少的材料。这减少了重置工具所需的力，这在水平井中是特别有利的。密封孔可以在出口处稍宽一些; 杯子膨胀到该出口直径，确保当杯子通过较小直径入口部分返回时过盈配合。密封孔的进入端可以包括纵向凹槽。这防止活塞杯通过防止围绕唇缘的流体密封而破裂，直到杯的大部分位于密封孔内。

摘要： Un método puede incluir implementar un dispositivo de taponamiento en un pozo, en donde el dispositivo de taponamiento incluye un cuerpo, y un material exterior que rodea el cuerpo y que tiene una flexibilidad mayor que la de un material del cuerpo, y transportar el dispositivo de taponamiento mediante el flujo del fluido llevándolo a entrar en contacto con la abertura, en donde el cuerpo impide que el dispositivo de taponamiento se extruya a través de la abertura, y el material exterior bloquea el flujo del fluido entre el cuerpo y la apertura. En otro método, el dispositivo de taponamiento puede incluir por lo menos dos cuerpos, y un elemento de arandela conectado entre los cuerpos, teniendo la arandela una forma general de disco y comprende un orificio, una línea que se extiende a través del orificio y conectada a los cuerpos en respectivos lados opuestos del elemento de arandela, impidiendo el elemento de arandela que el dispositivo de taponamiento sea transportado a través de la abertura, y el elemento de arandela bloquea el flujo del fluido a través de la abertura.

摘要： A compression indication tool can include a flow passage and a valve that in a closed configuration prevents fluid communication between the flow passage and an exterior of the tool, and in an open configuration permits fluid communication between the flow passage and the exterior of the tool. The valve is opened in response to application of a predetermined longitudinal compressive load to the compression indication tool. A method can include connecting a compression indication tool in a tool string, the tool including a valve that prevents fluid communication between an interior flow passage and an exterior of the tool, deploying the tool string into the well, and applying a predetermined longitudinal compressive load to the tool string, thereby opening the valve to permit fluid communication between the interior flow passage and the exterior of the tool.

摘要： A frac valve can include an outer housing with at least one port which provides for fluid communication between an interior and an exterior of the outer housing, and a sleeve releasably secured against displacement between a closed position in which the sleeve blocks flow through the port and an open position in which flow through the port is permitted. The sleeve may be press-fit in the outer housing as a result of the displacement. A method of operating a frac valve can include connecting the frac valve in a tubular string, and displacing a sleeve of the frac valve between closed and open positions. The displacing step can include deforming the sleeve and/or an outer housing of the frac valve, thereby preventing relative rotation between the sleeve and the outer housing.

摘要： A method can include deploying a plugging device into a well, the plugging device including a body, and an outer material enveloping the body and having a greater flexibility than a material of the body, and conveying the plugging device by fluid flow into engagement with the opening, the body preventing the plugging device from extruding through the opening, and the outer material blocking the fluid flow between the body and the opening. In another method, the plugging device can include at least two bodies, and a washer element connected between the bodies, the washer element being generally disk-shaped and comprising a hole, a line extending through the hole and connected to the bodies on respective opposite sides of the washer element, the washer element preventing the plugging device from being conveyed through the opening, and the washer element blocking the fluid flow through the opening.

摘要： ABSTRACT OF THE DISCLOSURE A method can include positioning a flow restrictor in a wellbore that penetrates a formation interval, then displacing the flow restrictor along the wellbore away from the surface, thereby permitting flow into an interval section from a wellbore section between the flow restrictor and the surface, blocking the flow from the wellbore section into the interval section, and displacing the flow restrictor away from the surface, thereby permitting flow from the wellbore section into another interval section farther along the wellbore from the surface. A system can include a flow restrictor that restricts flow through an annulus surrounding the flow restrictor, and plugging devices disposed in a wellbore section positioned between the flow restrictor and a surface of the well. Flow from the wellbore section into a formation interval section is permitted prior to being blocked by the plugging devices. Date Recue/Date Received 2020-11-25

摘要： Tools and methods for abrasively cutting downhole pipes and casing. The tools and methods are ideally suited for situations where the pipe to be cut or perforated is positioned partly or wholly inside another pipe and damage to the outer pipe must be avoided. The jet nozzles are positioned at a non-normal angle to the target surface to reduce the jets' effective cutting distance. While pumping the abrasive fluid, the jets are supported at a selected radial distance from the target surface so that within a predetermined operating time the jets will cut or perforate the inner pipe but leave the outer pipe substantially intact. The tool may be rotated with a motor to perform cutoff operations or held in a fixed position for perforating.

摘要： A system for use with a well can include a perforating assembly with at least one perforator, the perforating assembly conveyed through a wellbore with fluid flow through the wellbore, and plugging devices spaced apart from the perforating assembly in the wellbore, the plugging devices conveyed through the wellbore with the fluid flow. A method of deploying plugging devices in a wellbore can include conveying a perforating assembly including a dispensing tool through the wellbore, the dispensing tool including a container, and then releasing the plugging devices from the container into the wellbore at a downhole location. Another method of deploying plugging devices in a wellbore can include conveying the plugging devices through the wellbore with fluid flow through the wellbore, and conveying a perforating assembly through the wellbore while the plugging devices are being conveyed through the wellbore.

摘要： A method of restoring flow through an opening in a well, the opening being blocked by a plugging device, can include conveying a well tool into the well, contacting the plugging device with the well tool, and permitting flow through the opening as a result of the contacting step. Another method of restoring flow through an opening blocked by a plugging device in a well can include conveying a well tool into the well, reducing pressure in the well with the well tool, and permitting flow through the opening as a result of the pressure reducing step.
