摘要： Implementations of the present invention relate generally to methods, systems, and apparatus for absorbing vibration and shock impulses created during drilling operations. In particular, implementations of the present invention include drill-string shock absorbers adapted to absorb longitudinal forces produced during a drilling operation. For example, drill-string shock absorbers in accordance with at least one implementation of the present invention include a generally cylindrical housing having a first end and a second end coupled together by a radially interlocking joint. Such a configuration can reduce mechanical failure and increase the operating life of the shock absorber by transmitting torsional forces directly between the ends of the housing and reducing stresses from being transferred to fastening means securing the first and second ends of the cylindrical housing together.
摘要翻译：本发明的实施方式总体上涉及用于吸收在钻探操作期间产生的振动和冲击脉冲的方法，系统和设备。特别地，本发明的实施方式包括适于吸收在钻井作业期间产生的纵向力的钻柱减震器。例如，根据本发明的至少一个实施方式的钻柱减震器包括大致圆柱形的壳体，该壳体具有通过径向互锁接头联接在一起的第一端部和第二端部。这种构造可通过在壳体的端部之间直接传递扭转力并减少传递到将圆柱形壳体的第一端和第二端固定在一起的紧固装置上的应力而减少机械故障并延长减震器的使用寿命。 p>

摘要： A valve system includes a load holding valve, a feed balancing valve, and a fast feed differential valve. The load holding valve may be in fluid communication with the load holding valve. The fast feed differential valve is configured to move between an engaged state and a disengaged state. In the engaged state the fast feed differential valve fluidly couples a ring side of a feed cylinder, the load holding valve, and a piston side of the feed cylinder to allow fluid to flow from the ring side to the piston side.

摘要： A hydraulic control system includes a first motor, a second motor, a pump operatively associated with the first motor, a first coupling valve operatively associated with the second motor, first parallel valves operatively associated with the second motor, and a first switching valve operatively associated with the first coupling valve and the first parallel valves. The first switching valve is configured to switch the first coupling valve between a first coupling state and a second coupling state opposite the first coupling state and to switch the first parallel valves between a first parallel state and a second parallel state opposite the first parallel state. While the first parallel valves are in the first parallel state a portion of the output of the first motor drives the second motor while the first parallel valves are in the second parallel state, the output of the pump drives the second motor.
