Abstract
A pump assembly having an inhibitor tube is provided for lifting produced fluids to the surface. The pump assembly includes a pump and may optionally include a gas separator. The pump assembly includes an inhibitor tube having an outlet configured to be in fluid communication with the suction opening of either the pump or the gas separator. The inhibitor tube allows for the separation of gas from the produced fluid prior to the produced fluid entering the gas separator or the pump.
Claims17
A pump assembly comprising:
- a pump having a suction opening;
- a motor configured to drive the pump;
- and
- an inhibitor tube having an outlet configured to be in fluid communication with the suction opening;
- wherein the inhibitor tube does not surround the pump,
- wherein the inhibitor tube has an intake and wherein the intake is disposed above the inhibitor tube outlet, and
- wherein a gas separator is configured to discharge a substantially gas portion at a point between the inhibitor intake and the inhibitor outlet.
4 more elements
A pump assembly comprising:
- a pump;
- a gas separator configured to receive fluid via a suction inlet and discharge a substantially liquid portion toward the pump;
- and
- an inhibitor tube having an inhibitor outlet disposed proximate to the suction inlet
- wherein the inhibitor tube does not surround the pump or gas separator, and
- wherein the inhibitor tube has an inhibitor inlet and wherein the inhibitor inlet is disposed above the inhibitor outlet.
3 more elements
A method for pumping comprising:
- providing an assembly comprising a pump having a suction opening in fluid communication with produced fluids, a motor configured to drive the pump, and an inhibitor tube having an inhibitor outlet in fluid communication with the suction opening, wherein the inhibitor tube does not surround the pump;
- placing the assembly in a wellbore;
- powering the motor to actuate the pump;
- wherein the placing the assembly in the wellbore comprises disposing the assembly so that an inhibitor inlet is disposed above the inhibitor outlet;
- allowing the produced fluids to pass through the inhibitor tube and separate into a substantially gas portion and a substantially liquid portion;
- pumping the substantially liquid portion up through production tubing;
- and
- allowing the substantially gas portion to move upward through an annulus.
