Abstract
A sand prevention injection-production device comprises a small pump cylinder, a small plunger, an upstream moving valve, a large pump cylinder, a center rod, a large plunger, a downstream valve, a connecting-tripping device, a fixing valve, an outer pipe, a sieve pipe and a sand setting tail pipe. The small pump cylinder is connected with the large pump cylinder which is connected with the sieve pipe and the sand setting tail pipe in sequence through the connecting-tripping device. The sieve pipe and the outer pipe are connected. The small plunger and the large plunger are arranged in the small pump cylinder and the large pump cylinder respectively. The small plunger and the large plunger are connected through the center rod and are provided with the upstream moving valve and the downstream moving valve respectively. The fixing valve is arranged on the upper portion of the connecting-tripping device. The sand prevention injection-production device is suitable for a sand production thickened oil layer, injection and production can be achieved, sand can be effectively prevented from entering the pump cylinders, oil-well pump abrasion is relieved, the service life of an oil-well pump is prolonged, oil well production stopping caused by the fact that the pump is blocked by sand is avoided, working cost is lowered, injection-production efficiency is improved, and oil well normal production is guaranteed.
Description
Technical field
the novel oil field well injection-extraction pump kind equipment that relates to, specifically a kind of sand control injection-recovery apparatus.
Background technology
at present, the sandstone reservoirs particularly in oil field, general oil well production is many half a year, will shake out in a large number, and along with the moisture continuous rising of oil well, producing zone position shakes out day by day serious, and the sand control screen that general oil well is used can not prevent that part powder fine sand from entering pump barrel effectively, make oil well pump wearing and tearing, reduce the application life of oil well pump, sand holddown fault has even occurred, caused oil well to stop production.
Summary of the invention
the purpose of this utility model is exactly in view of the foregoing defects the prior art has, designs a kind of sand control injection-recovery apparatus.
above-mentioned purpose is realized by following technical proposals:
the utility model comprises: little pump barrel, small plunger, upward-traveling valves, large pump barrel, center-pole, large plunger, lower travelling valve, on-off connector, standing valve, outer tube, screen casing, sand setting tail pipe.The little pump barrel of its sand control injection-recovery apparatus is connected with large pump barrel, large pump barrel is connected with screen casing, sand setting tail pipe successively by on-off connector, screen casing is connected with outer tube, outer tube top is connected with oil pipe; in little pump barrel and large pump barrel, be respectively equipped with small plunger and large plunger, small plunger top is connected with sucker rod, and small plunger is connected by center-pole with large plunger; be respectively equipped with upward-traveling valves and lower travelling valve, the top of on-off connector is provided with standing valve.
operating principle: during steam injection, above carry rod string, large pump barrel and standing valve and on-off connector disengagement, by oil pipe inner chamber, screen casing to oil reservoir steam injection.During oil pumping, transfer rod string, large pump barrel is connected with on-off connector with standing valve, starts oil pumping.
the beneficial effects of the utility model are: be applicable to the Heavy Oil Reservoir that shakes out, note is adopted dual-purpose, effectively prevents that sand grains from entering pump barrel, alleviate oil well pump wearing and tearing, extend oil well pump application life, avoid sand holddown to cause oil well to stop production, reduce operating cost, improve note and adopt efficiency, assurance oil well is normally produced.
