摘要： Signal communications at a drilling system generally includes communicating upwards or downwards from the rig floor. For example, signal communications upwards may comprise the control of a cementing head operation (e.g., actuating cementing head). Signal communications downwards may comprise the activation of tools and their confirmation (e.g., hole opening tools, liner hangers, and packers). Actuation may be performed via umbilicals, for example, via pressure spikes or the dropping of balls, darts, or radio-frequency identification (RFID) tags. However, issues may arise wherein, for example, a ball may not properly land to close a circulation valve. As another example, a cementing head could be over 100 feet above the rig floor, which may make it difficult for signal communications via an umbilical. Accordingly, what is needed are techniques and apparatus for activation of tools and their confirmation by a remote communication system.
摘要翻译： 在钻井系统中的信号通信通常包括从钻井平台向上或向下传播。 例如，向上的信号通信可以包括对固井头操作（例如，致动固井头）的控制。 向下的信号通信可以包括启动工具及其确认（例如，开孔工具，衬管悬挂器和封隔器）。 致动可以通过脐带，例如通过压力尖峰或掉落球，飞镖或射频识别（RFID）标签来执行。 然而，可能会出现这样的问题，例如，球可能没有适当地着陆以关闭循环阀。 作为另一个例子，固井头可以在钻台上方超过100英尺，这可能使得通过脐带的信号通信变得困难。 因此，需要的是用于激活工具的技术和装置及其由远程通信系统的确认。

摘要： A catcher for use in a wellbore includes a housing and an insert disposed within the housing. A method of using the catcher includes disintegrating at least a portion of the insert while the insert is held rotationally stationary with respect to the housing by a taper connection between the insert and the housing.

摘要： A tong for handling a tubular includes a jaw carrier having an active jaw movable from a retracted position to an extended position relative to the jaw carrier; a cam body disposed about the jaw carrier and rotatable relative to the cam body; and a brake assembly including an first brake member for engaging an upper surface coupled to the jaw carrier.

摘要： A riser extending from a floating rig has a riser manifold. A rig manifold can be manipulated by an arm to couple in an automated manner to the riser manifold when running the riser from the rig. The riser and rig manifolds have mechanical connectors that mechanically connect them. Additionally, the manifolds have flow couplings mating together for conducting flow in at least one flow connection, and the manifolds control couplings mating together for conducting control in at least one flow connection. At least one of the manifolds has at least one valve controllable with the at least one control connection and configured to control fluid communication for the at least one flow connection between at least one rig flow line and an internal passage of the riser.

摘要： A choke can include a variable flow restrictor, external ports in communication with a flow passage respectively upstream and downstream of the flow restrictor, and sensor(s) in communication with the external ports. A method can include flowing a well fluid through a flow passage in a body of a choke including a variable flow restrictor, measuring a pressure differential between external ports in communication with respective upstream and downstream sides of the flow restrictor, and operating the flow restrictor, thereby varying a restriction to the flow through the flow passage, in response to the measured pressure differential. A well system can include a well fluid pump, a flow choke including a variable flow restrictor operable by an actuator that includes a displaceable stem and a stem seal that isolates the actuator from the well fluid in the flow choke, and a control system that operates the actuator.

摘要： A method of making-up tubular string components can include inputting to an image processor image data output from at least one camera, the image processor in response detecting positions of a tubular and a mark on another tubular, threading the tubulars with each other while inputting position data from the image processor to a controller, and the controller terminating the threading in response to the position of the mark relative to the position of the first tubular being within a predetermined range. Another method of making-up tubular string components can include, in response to inputting image data to an image processor, the image processor detecting longitudinal positions of two tubulars, threading the tubulars with each other, and a controller terminating the threading in response to the longitudinal position of one tubular relative to the longitudinal position of the other tubular being within a predetermined range.

摘要： A wellbore isolation assembly includes an outer component and an inner component. The outer component is disposed at a first location in a wellbore. The inner component is disposed at a second location in the wellbore. The inner component is moved from the second location into engagement with the outer component at the first location to form a barrier within the wellbore. When deployed in the wellbore, the barrier inhibits passage of fluids. The wellbore isolation assembly is then retrieved from the wellbore.

摘要： Methods and apparatus to control the acoustic properties of optical cables used as in-well oil and gas probes for acoustic monitoring, such as distributed acoustic sensing (DAS). One example aspect provides a solid path for the acoustic wave to propagate from an outside armor layer of the cable to the sensing optical waveguide embedded therein. Another example aspect offers ways to spatially dispose the optical sensing elements to create response delays indicative of the propagation speed and/or direction of an acoustic wave. Yet another example aspect provides ways to utilize additional spectral interrogation to increase ultimate spatial resolution. Yet another example aspect provides ways to locally vary the acoustic properties along the length of the cable.

A gap is present between the rotary base and the at least one rotary arm for receiving the tubular when the at least one rotary arm is in the open position. The gap is closed when the at least one rotary arm is in the closed position.
