摘要： Downhole tool fluid flow control apparatus including a first fluid valve between a first portion of a first flowline and a second portion of a second flowline. The first and second flowlines are adjacent each other. A second fluid valve is between a second portion of the first flowline and a first portion of the second flowline. The first and second fluid valves are controllable to cause fluid flow between the first portion of the first flowline and the second portion of the second flowline or between the first portion of the second flowline and the second portion of the first flowline.

摘要： Apparatus and methods to control fluid flow in a downhole tool are disclosed. A disclosed example system includes a hydraulically actuatable device having a cavity for receiving pressurized hydraulic fluid stored by a reservoir, a first and a second hydraulic pump, a motor and means for selectively flowing hydraulic fluid from the outlet of at least one of the first and second pumps to the at least one cavity. The first and second hydraulic pumps include an inlet fluidly coupled to the reservoir and an outlet fluidly coupled to the cavity, and the motor is operatively coupled to at least one of the pumps.

摘要： A method, according to one or more aspects of the present disclosure, for operating a positive displacement pump of a downhole tool comprises supplying a hydraulic pressure to the pump to actuate a two-stroke piston to displace fluid at least partially through the downhole tool; moving the piston in a first stroke direction; and reversing the direction of the piston upon completion of the first stroke of the piston. Completion of a stroke may comprise a head of the piston substantially abutting an end wall of a chamber of the pump.
