摘要： A release mechanism for incorporation into a logging head. The release mechanism may be a tensile release mechanism that employs a plurality of tensile members for interchangeable insertion into a plurality of tensile compartments. As a result, a weakpoint for the logging head may be user defined on location at the oilfield. Furthermore, for potentially deeper wells, a rotatable release mechanism may be alternatively or additionally incorporated into the logging head. The rotatable release mechanism may be employed to effectuate a release of the logging head upon signaling from surface equipment. Additionally, the rotatable release mechanism may be powered to achieve the release solely from a downhole power source.

摘要： A setting mechanism is made to respond to hydrostatic pressure. Upon reaching a predetermined depth corresponding to a given pressure, a pilot piston is shifted to allow well fluids to bypass a first set of piston seals and reach a second set. A shear pin that held the pilot piston in position is broken as the hydrostatic pressure increases with greater depth attained. However, the shifting of the pilot piston does not cause the main piston in the assembly to set the downhole tool. The action of the well fluids on the secondary seal set on the pilot piston eventually fail the second seal set allowing hydrostatic pressure to bypass them and actuate the main piston that will set the downhole tool. Raising the tool from the wellbore allows the spring acting on the pilot piston to seal in a bore to isolate hydrostatic pressure from the operating piston.
摘要翻译：进行静水压力的设定机构。在达到对应于给定压力的预定深度时，先导活塞被移动以允许井流体绕过第一组活塞密封件并到达第二组。将导向活塞保持在适当位置的剪切销随着静水压力增加而达到较大的深度而断裂。然而，先导活塞的移动不会导致组件中的主活塞设置井下工具。井液对先导活塞上的次级密封件的作用最终不能通过第二密封组，允许静水压力绕过它们并致动将设置井下工具的主活塞。从井眼提升工具允许作用在先导活塞上的弹簧密封在孔中，以将流体静压与工作活塞隔离。

摘要： A packer setting device provides a buffered setting mechanism as a substantially incompressible fluid is selectively flowed into a compressible fluid chamber to compress a compressible fluid. This fluid transfer causes movement of a setting sleeve so that an associated packer device is set within a wellbore.

摘要： An isolation device operatively coupled to a wellbore tool is activated upon receiving fluid that a predetermined applied pressure. When the fluid string reaches the predetermined applied pressure, the isolation device undertakes a specified action such as longitudinal movement, rotation, expansion, etc. that actuates or operates the wellbore tool. Premature actuation of the wellbore tool is prevented by applying a resistive force to the isolation device that, alone or in cooperation with another mechanism, arrests movement of the isolation device. This resistive force is generated by applied pressure of the fluid in the work string.

摘要： This invention provides a method for controlling production operations using fiber optic devices. An optical fiber carrying fiber-optic sensors is deployed downhole to provide information about downhole conditions. Parameters related to the chemicals being used for surface treatments are measured in real time and on-line, and these measured parameters are used to control the dosage of chemicals into the surface treatment system. The information is also used to control downhole devices that may be a packer, choke, sliding sleeve, perforating device, flow control valve, completion device, an anchor or any other device. Provision is also made for control of secondary recovery operations online using the downhole sensors to monitor the reservoir conditions. The present invention also provides a method of generating motive power in a wellbore utilizing optical energy. This can be done directly or indirectly, e.g., by first producing electrical energy that is then converted to another form of energy.

摘要： A downhole drilling tractor for moving within a borehole comprises a tractor body, two packerfeet, two aft propulsion cylinders, and two forward propulsion cylinders. The body comprises aft and forward shafts and a central control assembly. The packerfeet and propulsion cylinders are slidably engaged with the tractor body. Drilling fluid can be delivered to the packerfeet to cause the packerfeet to grip onto the borehole wall. Drilling fluid can be delivered to the propulsion cylinders to selectively provide downhole or uphole hydraulic thrust to the tractor body. The tractor receives drilling fluid from a drill string extending to the surface. A system of spool valves in the control assembly controls the distribution of drilling fluid to the packerfeet and cylinders. The valve positions are controlled by motors. A programmable electronic logic component on the tractor receives control signals from the surface and feedback signals from various sensors on the tool. The feedback signals may include pressure, position, and load signals. The logic component also generates and transmits command signals to the motors, to electronically sequence the valves. Advantageously, the logic component operates according to a control algorithm for intelligently sequencing the valves to control the speed, thrust, and direction of the tractor.
