Abstract
The utility model relates to a dual-purpose sand pump used in an oil production well of an oil field and a coalbed methane well. The upper part of a base cone is in threaded connection with the lower part of a check valve A, the upper part of the check valve A is in threaded connection with the lower part of a sand storage pipe, the upper part of the sand storage pipe is in threaded connection with the lower part of a lower connector, the upper part of the lower connector is in threaded connection with a sand pump cylinder, a plunger is in threaded connection with a pull rod and is installed in the sand pump cylinder, the lower part of the plunger is provided with a sealing ring, the upper part of the sand pump cylinder is in threaded connection with a gland, a part of the pull rod, penetrating through the gland, is in threaded connection with an adapter, the upper part of the adapter is in threaded connection with a check valve B, the check valve B is in threaded connection with an upper connector, and the left side and the right side of the upper connector are provided with water outlets. The device can avoid loss and pulverized coal precipitation in the coalbed methane production well when sand at the bottoms of the wells is removed, and is convenient to construct, low in cost and high in efficiency.
Description
Technical field
The utility model relates to a kind of sand pump, particularly a kind of oil well, the dual-purpose sand pump of coal-seam gas gas recovery well.The technical field that belongs to the oilfield exploitation aspect.
Background technique
The latter period of oilfield development strata pressure descends at present, underground sand content high or because of original formation pressure low, all may with the clear water sand washing time, produce leakage, some oil recovery well meeting severe leakage, therefore bring pollution in various degree to oil reservoir, this will affect the height of its output, even the final rate of adopting of receiving of impact.
Summary of the invention
The deficiency existed for the problems referred to above, the purpose of this utility model is to provide the deficiency that a kind of oil well, the dual-purpose sand pump of coal-seam gas gas recovery well exist to overcome prior art.
The technical solution of the utility model is as follows: a kind of oil well, the dual-purpose sand pump of coal-seam gas gas recovery well, base cone (1) top is connected with the lower thread of one-way valve A (2), one-way valve A (2) top is connected with storage sand tube (3) lower thread, storage sand tube (3) top is connected with lower contact (4) lower thread, and lower contact (4) top is threaded with sand pump cylinder (5).Plunger (7) is threaded with pull bar (8) and is arranged in sand pump cylinder (5).Plunger (7) bottom is equipped with seal ring (9).The top of sand pump cylinder (5) is threaded with gland (6).Pull bar (8) is threaded with variable buckle (10) through the part of gland (6), and variable buckle (10) top is threaded with one-way valve B (11), and one-way valve B (11) is threaded with upper connection (12).The left and right sides of upper connection (12) is provided with water outlet (13).
The utlity model has following characteristics: this device not only can be avoided leakage and gas recovery well coal dust precipitation removing the shaft bottom sand, and easy construction, expense is low, efficiency is high.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation;
1 base cone, 2 one-way valve A, 3 storage sand tubes, 4 lower contacts, 5 sand pump cylinders, 6 glands, 7 plungers, 8 pull bars, 9 seal rings, 10 variable buckles, 11 one-way valve B, 12 upper connections, 13 osculums in figure.
