摘要： A reciprocating well pumping unit includes a fluid-driven cylinder to drive a reciprocating rod assembly. A valve controls fluid delivery to the cylinder, the valve having a valve spool capable of being positioned in a first position or a second position, the valve in the first position causing fluid flow that allows the lifting rod to extend, the valve in the second position causing fluid flow that allows the lifting rod to retract. A detent assembly provides resistance to movement of the valve spool between the second and first positions. A control rod is coupled to and moves with the lifting rod. A spring is capable of storing energy as the control rod is moved in the first direction and a rod stop engages the spring, the spring engaging the valve spool as energy is stored in the spring to urge the valve spool toward the first position.

摘要： Systems and methods are presented for drilling a wellbore with a portion having a short radius of curvature. The systems include a drill assembly having a motor and a tubular housing. An actuator is at least partially disposed within the tubular housing and couples the motor to the tubular housing. The actuator is configured to selectively articulate the drill assembly between a straight configuration and a bent configuration. At least one torque anchor is fluidly-coupled to a trailing end of the drill assembly. Methods are presented for selectively articulating the drill assembly to form the wellbore, including the portion having short radius of curvature. Other systems and methods are presented.
