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： An apparatus and method for retrieving debris from the well bore of an oil or gas well. The apparatus comprises a junk basket with a flow passage that allows fluid to be jetted out end of the tool while the tubing string is advanced to stir up the debris in the well fluids and facilitate capture of the debris in the strainer basket. Importantly, upon encountering a plug of sand or other debris in the well bore, fluid flow through the tool can be increased to work on the plug until it breaks apart. Advancement of the tubing string can be halted and resumed, as needed, in combination with control of the fluid flow through the tool until the junk basket is full or the targeted debris is collected, whereupon the junk basket is withdrawn. The junk basket may be deployed on coiled tubing or a string of drill pipe.

摘要： A method and system for installing a Christmas tree in place of a blowout preventer on a wellhead. The donut in the wellhead BOP is landed using a coiled tubing injector. Then the wellhead BOP then is removed and the Christmas tree is installed also using the same crane that supported the coiled tubing injector. This employs the coiled tubing rig already in use at the well site for a previous operation, such as plug drilling or perforating and fracturing. Notably, the system provides a second seal, such as a ceramic disk, below the donut, for added safety while the Christmas tree is installed. The tool string used to install the donut includes a safety union so that the tool string can be disconnected after the donut is landed and locked into place.

摘要： A vibrating tool comprising a hammer and valve that oscillate axially inside a housing to produce vibrations solely in response to fluid flow through the tool at an operating flow rate. The valve is supported by a spring that resists compression until a minimum operating flow rate is achieved, and hammer is also spring-loaded. When the valve strokes down and engages the hammer, flow through the hammer is restricted. Increased fluid pressure pushes the hammer down away from the valve, resulting in a sudden decrease in pressure, allowing both the hammer and valve to rebound and create vibrational impacts. The cycle repeats continuously as long as an adequate flow rate is maintained.

摘要： A method of treating each of multiple formation zones in a subterranean well can include isolating two of the zones from each other in the wellbore with a plug assembly positioned in the wellbore; treating one of the zones by flowing a treatment fluid through openings that provide fluid communication between the wellbore and one of the zones; then blocking flow through the openings; increasing pressure in the wellbore in response to the blocking; and opening the plug assembly in response to the pressure increasing. A well treatment system for treating each of multiple zones intersected by a wellbore can include multiple plug assemblies in the wellbore, each of the plug assemblies isolating a respective adjacent pair of the zones from each other in the wellbore. Each of the plug assemblies opens in response to a respective predetermined pressure differential applied across the plug assembly.

摘要： A system for use with a subterranean well can include a deployment apparatus configured to deploy one or more plugging devices into a fluid flow. The plugging devices are conveyed into the well by the fluid flow. The deployment apparatus can include multiple queues, different numbers of the plugging devices being contained in respective different ones of the queues. A method of deploying plugging devices can include connecting multiple queues of the plugging devices to a conduit, and deploying the plugging devices from a selected combination of the queues into the conduit. In another system, each of the plugging devices may include a body, and lines or fibers extending outwardly from the body.

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 circulating valve assembly can include a valve controlling flow between an interior and an exterior of the assembly, another valve controlling flow between sections of a flow passage extending through the assembly, and an actuator that both opens one valve and closes the other valve in response to each of multiple positive pressure differentials from the interior to the exterior. A system for use with a well can include a circulating valve assembly controlling flow through a tubular string and a well tool connected in the tubular string downstream of the assembly. In one configuration of the assembly, the flow passes through the well tool. In another configuration, the flow passes from the tubular string to an annulus external to the tubular string, with the flow substantially bypassing the well tool. The assembly cycles between the configurations in response to alternating increases and decreases in the flow.
