Description
Technical field
The utility model relates to a kind of movable casing gas recovery device, solves casing gas and reclaims problem.
Background technology
Oilfield pumping well is in order to improve well oil output at present, through being everlasting, casing gas is put at Christmas tree casing gate place, improve producing fluid level, suck coefficient thereby improve oil well pump, reach the purpose that improves pump efficiency, casing gas directly enters ground, the one, contaminated environment, the 2nd, waste energy, the staff reclaims casing gas for this reason, and the approach of recovery is to be recovered to gathering line.Retracting device is fixed on import, and every mouthful of well installation is a set of, and input cost is high, and the well head installation procedure is lack of standardization, in disorder not attractive in appearance, does not meet the requirement of carrying out production strictly in line with rules and regulations, and often suffers lawless person's destruction.
Summary of the invention
The purpose of this utility model is to provide a kind of movable casing gas recovery device, overcomes the defect that above-mentioned prior art exists.
The technical solution of the utility model is achieved in the following ways:
The utility model comprises body, ball-and-seat, plug, packing pressure cap, packing and spring pressure regulator, it is characterized in that body is made as tubular, one end is provided with hoop, the other end is provided with the plug that is threaded, central part at plug is provided with the packing pressure cap be threaded with plug, packing pressure cap is pressed with packing below, through packing pressure cap, the central part of packing and plug is provided with the spring pressure-setting valve, be provided with the valve ball seat at the middle part of body, the valve ball seat is provided with valve ball, be provided with spring between valve ball and spring pressure regulator, be provided with pressure tapping and pressure meter at the valve ball seat on following body, be provided with atmospheric valve and head associated gas recovering valve on the body of valve ball seat top, head associated gas recovering valve is connected with single current by high-pressure hose, the hoop of body is connected with sleeve gate by clip, and ball-and-seat is connected with the sample valve on gathering line.
Plug is made as cylindrical, and top is provided with the spanner rib, and bottom is provided with the male thread be connected with body, and central part is provided with circular packing chamber, and top, packing chamber is provided with the box thread be threaded with packing pressure cap.
Packing pressure cap is made as cylindrical, and top is provided with the spanner rib, and bottom is provided with male thread, and the central part periphery is provided with box thread.
The spring pressure regulator comprises handle, screw mandrel and pressing plate, screw mandrel upper end and handle welding, and lower end is provided with shaven head, with the deep-slotted chip breaker on pressing plate, is connected.
Compared with the prior art the utility model has the following advantages:
The utility model is connected and there is no pad with well head, and the installation that need not stop production is easy for installation, easy to carry, and a set of casing gas recovering device can be for many wells.
But level pressure is regulated venting, can avoid the exitting excessive impulsion sand production in oil of pressure reduction, sand plug oil well.
The accompanying drawing explanation
Fig. 1-structural representation of the present utility model;
1-pressure meter in figure, 2-body, 3-atmospheric valve, 4-head associated gas recovering valve, 5-valve ball seat, 6-valve ball, 7-spring, 8-plug, 9-packing, 10-packing pressure cap, 11-spring pressure-setting valve, 12-high-pressure hose, 13-ball-and-seat.
The specific embodiment
For further disclosing the technical solution of the utility model, below in conjunction with Figure of description, by embodiment, elaborate:
The utility model comprises body 2, ball-and-seat 13, plug 8, packing pressure cap 10, packing 9 and spring pressure-setting valve 11, it is characterized in that body 2 is made as tubular, one end is provided with hoop, the other end is provided with the plug 8 that is threaded, central part at plug 8 is provided with the packing pressure cap 10 be threaded with plug 8, packing pressure cap 10 is pressed with packing 9 below, through packing pressure cap 10, the central part of packing 9 and plug 8 is provided with spring pressure-setting valve 11, be provided with valve ball seat 5 at the middle part of body 2, valve ball seat 5 is provided with valve ball 6, be provided with spring 7 between valve ball 6 and spring pressure regulator 11, be provided with pressure tapping and pressure meter 1 at valve ball seat 5 on following body, be provided with atmospheric valve 3 and head associated gas recovering valve 4 on the body of valve ball seat 5 tops, head associated gas recovering valve 4 is connected with ball-and-seat 13 by high-pressure hose 12, the hoop of body 2 is connected with sleeve gate by clip, and ball-and-seat 13 is connected with the sample valve on gathering line.
When application the utility model, at first the hoop of body 2 is connected with sleeve gate by clip, air outlet valve 4 is connected with ball-and-seat 13 by high-pressure hose 12, ball-and-seat 13 is connected with the sample valve on gathering line, open sleeve gate and start getter, if discharge quantity is too large, gap between valve ball 6 and valve ball seat 5 is too large, for preventing the oil reservoir impulsion, shake out, utilize spring pressure regulator 11 pressing springs 7, spring pressure valve ball 6, make the gap smaller between valve ball 6 and valve ball seat, discharge quantity diminishes, along with the pressure decreased on pressure meter, gradually discharge spring pressure, casing gas is recovered to gathering line gradually, when casing pressure during lower than the pressure of oil-collecting main line, ball-and-seat 13 is closed.The casing gas recovery operation completes, and shuts sleeve gate and sample valve, and sleeve pipe spring pressure regulator is discharged into zero to the bounce of spring, opens atmospheric valve 3 and carries out emptying, unloads movable casing gas recovery device, transfers to other oil wells and carries out recovery of casing gas.
