摘要： An adjustable valve for controlling fluid flow between an inlet and an outlet in a valve. A compressed spring biases a valve member against the valve inlet to prevent fluid flow until the fluid pressure reaches a certain level. One end of the spring contacts a hydraulic plunger which is moved with a hydraulic fluid. The hydraulic fluid pressure can be raised to increase the spring force acting against the valve element, and the hydraulic fluid pressure can be reduced to decrease the spring force acting against the valve element. The flow rate at the valve outlet can be monitored, and flow rate signals can be transmitted to a controller for adjusting the hydraulic fluid pressure in response to the flow rate detected.

摘要： Apparatus for positioning a detector at a plurality of depth locations within a borehole includes an elongated body member having a pair of diametrically opposed hydraulic pad displcement members mounted thereon. A pad mounting member is pivotally attached to each pad displacement member and a pair of borehole wall contacting members are pivotally attached to each pad mounting member. A signal detector is mounted behind one or more of the pad members. At each test depth a hydraulic power system deploys the pad displacement members from the body to an extended position and extends the wall engaging pad members into contact with the borehole wall. A redundant hydraulic safety system is provided in case of electrical system failure for releasing the pad member. The safety system includes, in addition to an electrically operated release valve, a clock operated release valve and a tension actuated release valve, all able to release hydraulic pressure on the displacement members in case of the failure of another, allowing withdrawal of the apparatus from the borehole.

摘要： An improved check valve for selectively controlling the flow of fluid through a valve seat. A spring biases a plunger against the valve seat when the fluid is stationary. Movement of the fluid pushes the valve plunger against the spring to open the aperture of the valve seat. An actuator selectively exerts a force against the plunger to close the plunger against the valve seat. In one embodiment of the invention, the actuator directs a pressurized fluid against a second end of the plunger, and a seal prevents leakage of such fluid toward the plunger first end in contact with the valve seat. A cavity between the seal and the plunger first end can be vented to the atmosphere to maintain the pressure differential created by the pressurized fluid against the plunger second end.
摘要翻译：一种用于选择性地控制通过阀座的流体流动的改进的止回阀。当流体静止时，弹簧将柱塞偏压到阀座上。流体的移动将阀柱塞推靠在弹簧上以打开阀座的孔。致动器选择性地向柱塞施加力以将柱塞紧靠阀座。在本发明的一个实施例中，致动器将加压流体引导到柱塞的第二端，并且密封件防止这种流体朝着与阀座接触的柱塞第一端的泄漏。密封件和柱塞第一端之间的空腔可以排放到大气中，以保持加压流体相对于柱塞第二端产生的压力差。

摘要： A method and apparatus for acquiring a plurality of sidewall cores from an earth formation intersected by a wellbore while a coring tool is located downhole. A sidewall coring tool is provided having an internal core receptacle for receiving and storing sidewall cores in serial orientation. The coring tool incorporates a movable bit box providing rotary support and linear coring and retracting movement of a rotary coring bit. A bit box tilting and rotation actuator is incorporated within the coring tool for achieving breaking at the core sample from the formation and for selectively positioning of the bit box and rotary coring bit at a coring position where the bit is oriented in normal relation with the axis of the wellbore and a core ejecting position where the rotary coring bit is positioned in registry with the internal core receptacle for deposit of cores in serially oriented relation therein. Another actuator is provided for accomplishing lateral coring and retracting movement of the rotary coring bit for acquiring a core and for retracting the bit and core within the coring tool. A third actuator is provided within the coring tool for displacing cores from the rotary coring bit into the core receptacle after the rotary coring bit has been positioned in registry with the core receptacle. A mechanism is also provided for locking the coring bit against inadvertent extension during bit box rotation. The sidewall coring mechanism further incorporates a reduction gear transmission permitting slow speed, high torque rotation of the coring bit, which transmission is automatically disengaged when the bit box is rotated from the coring position.

摘要： An apparatus for measuring the resistivity of earth formations penetrated by a wellbore having a conductive conduit. The apparatus includes an elongated sonde mandrel, a plurality of electrodes positioned at axially spaced apart locations along the mandrel, the electrodes being electrically insulated from the mandrel and from each other, the electrodes adapted to electrically contact the conduit and positioned collinearly so that the electrodes contact the conduit when the mandrel is radially displaced towards the wall of the conduit. Some electrodes are for injecting electrical current into the conduit, other electrodes are for measuring voltage drop along the conduit at axially spaced apart locations. The mandrel includes selectively extensible locking arms for urging the mandrel into contact with the conduit. The arms are radially positioned opposite to the electrodes. The apparatus includes a source of electrical current connected to the current injector electrodes, a circuit for measuring output of the source of electrical current, voltage measuring circuits connected to the voltage drop electrodes, and means for recording measurements of current and voltage drop.
