摘要： Methods and apparatus are provided which permit well testing operations to be performed downhole in a subterranean well. In various described methods, fluids flowed from a formation during a test may be disposed of downhole by injecting the fluids into the formation from which they were produced, or by injecting the fluids into another formation. In several of the embodiments of the invention, apparatus utilized in the methods permit convenient retrieval of samples of the formation fluids and provide enhanced data acquisition for monitoring of the test and for evaluation of the formation fluids.

摘要： Well tools are provided which although pressure responsive, may be maintained by a hydraulic lockout in a nonresponsive condition until a threshold actuation step is performed. This lockout may be achieved by a hydraulic mechanism which controls the rate at which pressure is transmitted to a fluid spring during periods of increased pressure at the pressure source. When the tool is desired to be responsive to pressure cycles, a valve may be opened by established a differential between the pressure in the fluid spring and the pressure source. Communication of pressure in the fluid spring to a movable mandrel will then allow operation of the well tool in response to pressure cycles at the pressure source in accordance with the established design of the well tool.
摘要翻译： 可以提供井工具，尽管压力响应，可以通过在无响应状态下的液压闭锁来维持，直到执行阈值致动步骤为止。 该锁定可以通过液压机构实现，该液压机构控制在压力源处的压力增加期间压力传递到流体弹簧的速率。 当工具希望响应于压力循环时，可以通过在流体弹簧和压力源之间的压力之间建立差异来打开阀门。 将流体弹簧中的压力传递到可移动的心轴将允许响应于在压力源处的压力循环根据井工具的已建立的设计操作井工具。

摘要： A safety valve system includes a safety valve having an actuator and a line connected to the actuator. The safety valve is operable by opening the line in the well, with the line being free of any connection to a surface control system. Another safety valve system includes multiple safety valves. An actuator of each safety valve is connected to an actuator of another safety valve via a line. A biasing force in each of the actuators is operative to close the respective one of the safety valves in response to opening of the line. The biasing force is produced at least in part by hydrostatic pressure in a well.

摘要： In a subterranean well completion a bi-directional signal transmission system includes an in-line acoustic transceiver mounted in a tubing string extending through the wellbore, the transceiver being disposed beneath a hanger structure engaging the tubing string. Via the tubing string the transceiver receives acoustic signals from well parameter sensing apparatus further downhole and converts the received acoustic signals to non-acoustic signals. The resulting non-acoustic signals are then transmitted upwardly through the hanger structure, to a signal receiving location, via cabling. In this manner, the hanger structure does not adversely affect the strength of either upwardly or downwardly transmitted signals traversing it. Alternatively, the acoustic well parameter signals received by the transceiver are converted to electromagnetic signals which pass through the earth, are picked up by a receiver external to the well completion, and then relayed to the receiving location.
摘要翻译： 在地下井完井中，双向信号传输系统包括安装在延伸穿过井筒的管柱中的直列式声收发器，该收发器设置在与油管柱接合的衣架结构下方。 通过管柱，收发器从井下参数传感装置进一步接收声信号，并将接收到的声信号转换成非声信号。 然后，所得到的非声学信号经由电缆布线向上穿过衣架结构传送到信号接收位置。 以这种方式，衣架结构不会对穿过其的向上或向下传递的信号的强度产生不利影响。 或者，由收发器接收的声学井参数信号被转换成通过地球的电磁信号，由完井完井之外的接收器拾取，然后中继到接收位置。

摘要： A system and method for controllably separating a conduit into an upper portion and a lower portion. The system includes a first valve in the upper portion of the conduit above a point of separation, and a second valve in the lower portion of the conduit below the point of separation. When the conduit is separated, the valves are actuated to cease flow therethrough and prevent loss of fluids into the seawater. A hang-off tool in the lower portion of the conduit engages the well and supports the lower portion of the conduit.
