Abstract
The utility model relates to a sucking oil-water well sand bailing device which is composed of a shallow metre drill 1, a roller 2, a sensor 3, a steel cable 4, a pulley block 5, a threaded joint 6, a counterweight rod 7, a plunger piston 8, a pump 9, a check valve 10, a sand anchor 11, a sand storage barrel 12 and a nib 13. The utility model is suitable for various oil-water wells with serious sand production; the utility model is an efficient path for solving the difficult problem of oil well sand production in the midanaphase of oil-field development; the utility model has the advantages that cost can be redueced by 100 thousand yuan for each oil well each year, the pump inspection period of the oil well can be prolonged, the effective working time of the oil-water wells is increased, and crude oil production rate is increased. At present, the process is partially applied in the Jinzhou Oil Production Plant of the Liaohe Oilfield, effect is good and foreground is optimistic.
Description
The utility model relates to preventing of using on a kind of field produces, and oil well sand from burying or the sand-bailing equipment of sand plug, particularly a kind of drawing-in type oil-water well sand-bailing equipment.
In the field produces development process, along with the prolongation of time, oil stream constantly washes away the rock stratum when oil reservoir injects pit shaft, with the structural deterioration of rock stratum, sand grains is brought in the well.Form sand in wherein a part of sand deposition into wells and bury or sand plug, increased oil flow resistance, reduce oil well output, sand post height can reach more than hundred meters in the sand plug severe patient well, and oil well is blocked, and oil well is stopped production; Another part sand is carried the emersion pit shaft by oily stream, and the meeting friction device blocks oil production equipment in the wells such as deep well pump piston, valve in uphill process.Adopt equipment such as pump truck, tank car to carry out sand washing at present, need 24 hours, cost is very high, and the sand in the oil-water well can't be flushed out fully ground, and residual sand easily causes oil well sand card, shortens pump detection period, weak effect, and complex process, safety factor is low.
The purpose of this utility model is to provide a kind of drawing-in type oil-water well sand-bailing equipment, and it can be enhanced productivity, and reduce cost, and technology is simple easy construction.
The purpose of this utility model is to realize like this, it comprises shallow rice rig (1), cylinder (2), sensor (3), wire rope (4), assembly pulley (5), threaded joint (6), weight linear meter (7), plunger (8), pump (9), ball-and-seat (10), sand anchor (11), cartridge (12), nib (13), on shallow rice rig (1), cylinder (2) is arranged, sensor (3), wire rope (4), assembly pulley (5), wire rope (4) hangs in the down-hole by assembly pulley (5), be connected with threaded joint (6) on the down-hole wire rope (4) in turn, weight linear meter (7), plunger (8), pump (9), ball-and-seat (10), sand anchor (11), cartridge (12), nib (13), down-hole partial devices all adopt thread connecting mode to connect.
Fig. 1 is a structural representation of the present utility model.
When work, drive the cylinder rotation by automobile power, transfer wire rope, by weighted lever, accelerate the equipment downstream rate, when the nib of lower end is met the sand face, stop to transfer wire rope, on carry wire rope and drive underground equipment and back and forth remove.On when carrying, after the profit in shaft bottom was taken sand and entered cartridge by ball-and-seat, sand was positioned in screen casing (sand anchor) detention of cartridge upper end, and profit is advanced into the pump work tube on continuing.When descending, the profit in the piston of the pump extruding seating nipple enters annular space through the ball-and-seat of upper end.Just finished a jig frequency.Back and forth carry out 15-20 time, just can the sand that general sand buries in the well have been dragged for.The sand that meets special thickness buries well, only needs to propose underground equipment behind aforesaid operations, and the sand in the cartridge is cleaned out, and repeating to go into the well once gets final product again.Transfer meter number and the tonnage of wire rope is presented on the instrument board by passing sensor in the construction.
The utility model is owing to adopted wire rope to hang in the down-hole by assembly pulley, reach the structure of pump, ball-and-seat, sand anchor, cartridge, be specially adapted to all kinds of serious oil-water wells that shake out, this equipment is a kind of effective way that solves an oil field development middle and later periods sand production difficult problem, annual every mouthful of well not only can reduce 150,000 yuan of operating costs, but also can prolong the pump detection period of oil well, and improve the oil-water well effective time, increase crude output.At present, this technology obtains certain applications in oil recovery factory, Jinzhou, Liaohe Oil Field, and effect is better, and prospect is very optimistic.
Claims (2)
1, a kind of drawing-in type oil-water well sand-bailing equipment, it comprises shallow rice rig (1), cylinder (2), sensor (3), wire rope (4), assembly pulley (5), threaded joint (6), weight linear meter (7), plunger (8), pump (9), ball-and-seat (10), sand anchor (11), cartridge (12), nib (13), it is characterized in that: on shallow rice rig (1), cylinder (2) is arranged, sensor (3), wire rope (4), assembly pulley (5), wire rope (4) hangs in the down-hole by assembly pulley (5), is connected with threaded joint (6) on the down-hole wire rope (4) in turn, weight linear meter (7), plunger (8), pump (9), ball-and-seat (10), sand anchor (11), cartridge (12), nib (13).
2, drawing-in type oil-water well sand-bailing equipment according to claim 1 is characterized in that: down-hole part threaded joint (6), weight linear meter (7), plunger (8), pump (9), ball-and-seat (10), sand anchor (11), cartridge (12), nib (13) all adopt thread connecting mode to connect.
