Technical Field
[0001] The utility model relates to the technical field of pumping equipment, and more particularly to an insertable downhole operation pumping equipment. Background Art
[0002] Insertion-type downhole pumping equipment is a type of pumping equipment that transports liquid or gas from one place to another, or injects it into a specific device or system. Insertion-type downhole pumping equipment is widely used in oil and gas extraction in the oil and natural gas fields, and is particularly suitable for discharging gas from oil wells containing large amounts of gas to increase oil and gas production.
[0003] The existing insertable downhole operation pump is used in daily operation because the working cylinder needs to be lowered into the oil pipe. Under the same conditions, the rod pump that can be lowered into the well has a smaller diameter and smaller displacement than the tube pump, which leads to slow transportation efficiency of the insertable downhole operation pump.
[0004] The existing plug-in downhole operation pump, when used in daily operation, will have a large swing of the pump barrel installed at the bottom of the equipment, which aggravates the wear of the sucker rod and the plunger limit sleeve, making the pump barrel unsuitable for use as a long-stroke pump.
