Problems solved by technology

[0006] It can be seen from this that no matter what kind of existing drive mode screw pump is used to exploit crude oil, it will not match the power drive mode of the currently used pumping unit, which will mean that the original tens of thousands of pumping units, sucker rods, etc. The power drive device of the rod plunger pump is all scrapped, which will cause a great waste of resources

Embodiment Construction

[0023] Figure 1 is an example of beam pumping unit, which mainly includes screw pump 1, power conversion mechanism 2, sucker rod 3, tubing 4, casing 5, wellhead 6, rope hanger 7, donkey head 8, and pumping unit Frame 9, beam 10, connecting rod 11, crank 12, speed reducer 13, belt pulley 14 and power machine 15 etc.

[0024] The power machine 15 drives the belt pulley 14 on the input shaft of the reducer to rotate through the belt transmission, after the reducer 13 decelerates, the output shaft of the reducer drives the crank 12 to rotate, and then through the connecting rod 11 in the crank linkage mechanism, the swing rod is The beam 10 reciprocates relative to the pumping frame 9, and the sucker rod 3 moves up and down linearly through the donkey head 8 and the rope hanger 7, and then through the power conversion mechanism 2 in this system, the sucker rod The reciprocating linear motion of 3 is converted into rotary motion, thereby driving the rotor of the screw pump to rotat...

Abstract

A straight driving screw pump oiling system comprises an oil pump, a pumping rod, a power converter and a screw pump, wherein one end of the power converter is connected with the pumping rod and another end is connected with the screw pump, when the pump drives the pumping rod up and down, the power converter can convert the motion of pumping rod into rotation to rotate the rotor of the screw pump to lift the oil. The invention can be used to pump high-dense high-sand oil, with long service life or the like.

Description

technical field [0001] The invention relates to the technical field of oil field exploitation, in particular to the technology of an oil extraction device. Background technique [0002] At present, most oilfields in my country have entered the middle and late stages of development, and the oilfields have basically lost the ability of self-spraying, and the mining method has changed from self-spraying to mechanical mining. Rod pumping machinery is currently the main oil pumping equipment in my country. By 2003, the number of mechanical oil production wells in my country had reached 90% of the total number of oil wells, and about 80% of mechanical oil production wells used rod plunger pumps for oil production. The output accounts for more than 75% of the total output. Among them, the beam pumping unit is the most widely used, and it also includes non-beam pumping units, friction lift pumping units, and linear motor-driven pumping units. With the continuous development of majo...
