Embodiment Construction

[0023] Embodiment 1 of the horizontal well anti-falling objects tubular oil well pump of the present invention, as figure 2 , image 3 shown, where figure 2 It is a structural schematic diagram of the upper half of the tubular oil well pump of the present invention, image 3 It is a schematic diagram of the structure of the lower part of the tubular oil well pump of the present invention. The tubular oil well pump is suitable for both vertical oil well pumping and horizontal section oil well pumping. When pumping oil for vertical oil wells, the tubular oil well pump The oil well pump is vertically lowered into the oil well, and the tubular oil well pump is placed horizontally when pumping oil for the horizontal oil well. The tubular oil well pump includes a pump barrel 3 whose axis extends in the up-down direction. The upper end of the pump barrel 3 is connected with the first joint 1 of the pump barrel, and the lower end is connected with the second joint 5 of the pump ba...

Abstract

The invention relates to a tubing oil well pump. The tubing oil well pump comprises a fixed valve and a protection cover for preventing impurities from falling in the fixed valve. The fixed valve comprises a fixed valve seat and a valve ball matched with the fixed valve seat; and a sedimentary cavity is formed in the periphery of the protection cover, and the fixed valve seat and the valve ball are located on the outer side of the protection cover. The valve ball and the fixed valve seat are located on the outer portion of the protection cover; and under the condition of ensuring the storage capacity of the sedimentary cavity, the radial size of the valve ball and the radial size of the fixed valve seat are not limited by the protection cover, the diameter of the fixed valve seat can reach the maximum as far as possible, the radius of the valve ball is made to be maximum as far as possible, and the oil pumping efficiency of the tubing oil well pump is improved as far as possible.

Description

technical field [0001] The invention relates to oil production equipment for oil production wells, in particular to a tubular oil well pump. Background technique [0002] As a kind of oil production equipment for oil production wells, oil well pumps are widely used in oil production in oil fields. At present, most oil production in oil fields is vertical well production, that is, oil production wells are vertical oil wells, and production pipes are lowered into the oil wells when pumping oil. Columns, production strings from top to bottom are generally oil pipes, well pumps, oil well tools, screens and plugs, etc. At present, with the advancement of drilling technology, various oilfields promote the application of horizontal well drilling and oil production technology according to the geological characteristics of the reservoir and the intensive production management mode. Whether it is a vertical well, a directional well or a horizontal The oil pipes, sucker rods and vario...
