The assembly relation is that a polish rod 1, a gas compression plunger 9, a sucker rod string 10 and a plunger pump plunger 15 are sequentially connected to form an inner rod string, a gas compression pump cylinder 8, an outer pipe 5, a sieve pipe 11, an oil pipe 12, a plunger pump cylinder 14, a liquid inlet check valve 16, a downhole gas-liquid separator 17 and a plug 18 are sequentially connected to form the oil pipe string, wherein the sieve pipe 11 is connected below the gas compression pump cylinder 8, and the lower end of the outer pipe 5 is connected to the bottom of the sieve pipe 11 through a transition joint.
The beneficial effects of the utility model are that, when interior post was down, feed liquor single current valve 16 closed, and the feed liquor single current valve in the plunger pump plunger 15 was opened, and the liquid in the oil pipe enters into more than plunger pump plunger 15, and when interior post went upward, liquid column 25 on plunger pump plunger 15 upper portion was through screen pipe 11, the annular space 24 of flowing through gas compression pump barrel 8 and outer tube 5, through flowing back single current valve 23 through fluid-discharge tube 22 discharge, realized the forced flowing back of oil pipe. Meanwhile, when the inner rod column moves downwards, gas separated by the underground gas-liquid separator 17 passes through the annular space of the oil pipe 12 and the sleeve 13 and is sucked into the gas compression pump cylinder 8 through the gas inlet pipeline 4, and when the inner rod column moves upwards, the gas in the gas compression pump cylinder 8 is forcibly compressed by the gas compression plunger 9 and is discharged through the gas outlet check valve 20 and the gas outlet pipe 21, so that the sleeve gas is forcibly discharged. The gas compression plunger 9 and the plunger pump plunger 15 are connected together through the sucker rod string 10 and the polish rod 1 and synchronously reciprocate up and down to realize synchronous suction and synchronous forced discharge of gas and liquid.
Drawings
Fig. 1 is a general diagram of a structure of a strong gas production system of an oil pipe strong drainage casing. The present invention will be further explained with reference to the drawings and examples.
Detailed Description
As shown in fig. 1, the oil pipe strong drainage casing strong gas production system is composed of a polish rod 1, a wellhead sealing device 2, a gas inlet check valve (3), a gas inlet pipeline (4), an outer pipe (5), a gas production tree oil pipe four-way 6, a gas production tree casing four-way 7, a gas compression pump cylinder (8), a gas compression plunger (9), a sucker rod column 10, a sieve pipe (11), an oil pipe 12, a casing 13, a plunger pump cylinder (14), a plunger pump plunger (15), a liquid inlet check valve (16), an underground gas-liquid separator (17), a plug (18), a gas outlet check valve (20), a gas outlet pipe (21), a liquid discharge pipe (22) and a liquid discharge check valve (23). The assembly relation is that a polish rod 1, a gas compression plunger (9), a sucker rod string 10 and a plunger pump plunger (15) are sequentially connected to form an inner rod string, a gas compression pump cylinder (8), an outer pipe (5), a sieve pipe (11), an oil pipe 12, a plunger pump cylinder (14), a liquid inlet check valve (16), an underground gas-liquid separator (17) and a plug (18) are sequentially connected to form the oil pipe string, wherein the sieve pipe (11) is connected below the gas compression pump cylinder (8), and the lower end of the outer pipe (5) is connected to the bottom of the sieve pipe (11) through a transition joint.
