摘要： A hydraulic pump avoids problems with gas lock found in conventional pumps. The pump draws in production fluid in a lower pump volume during the pump's upstroke and diverts the produced fluid to an upper pump volume during the downstroke. Spent power fluid is communicated to the upper pump volume during the pump's upstroke. The pump piston in the upstroke expels the entire volume via a check valve that communicates the upper pump volume with a discharge outlet. The check valve increasing the discharge pressure of the upper pump volume, the upper pump volume of the spent power fluid being greater than the upper pump volume, and the upper pump piston compressing produced gas in the upper pump volume all combine to prevent or reduce the chances that the pump will gas lock during operation.

摘要： The present invention relates to a control system for selectively supplying electrical power in a remote environment. The system comprises a plurality of electrical circuits, each designed to operate over a unique frequency passband. Power transmitted within the frequency passband of a circuit is filtered through that circuit to power a corresponding remote device. One or more remote devices can be simultaneously powered by transmitting power within the frequency passbands of the corresponding circuits. It is advantageous to design relatively narrow passbands to accommodate a relatively large number of circuits and corresponding devices for remote operation and a triac, rectifier or other suitable turn-on gate can be incorporated into each circuit to effectively control the width of the frequency passband of each circuit. Alternatively, an operational amplifier could be used.

摘要： The method of remotely actuating a downhole device provides the initiation of an acoustic signal. The acoustic signal is amplified within a resonance chamber and is transmitted down a fluid column in the tubing string or in the annulus around the tubing string. The signal can be coded to allow activation of multiple downhole devices. The use of a resonance chamber allows for the amplification of the actuation signal to ensure that a downhole receiver can detect it. The receiver can be either a transducer or a hydrophone. The apparatus and method allow for remote actuation without the need for intervention into the well.

摘要： The present invention provides apparatus and methods for controlling and/or powering downhole components without the need for control and/or power lines extending from the components to the surface of the well and without the need for power or control lines to be inserted into the wellbore along with the components. In one aspect of the invention, a borehole is lined with a casing, the casing having at least one aperture disposed. Adjacent the aperture, on the outer surface of the casing, is a docking station, which is permanently attached to the casing and includes a socket. After the casing is installed in the borehole, a downhole component can be lowered into the wellbore. The downhole component is equipped with a connector extending from an outer surface thereof. The connector assembly is disposable through the aperture in the casing and, the connector assembly can be connected to the socket of docking station.
