Description
Technical field
The utility model belongs to the oil field equipment field, relates to a kind of well-washing truck, particularly a kind of oil field special high-pressure well-washing truck.
Background technology
Now along with deepening continuously that the oilfield injection compound recovers the oil, the wax deposition situation of down-hole string is more for serious, have and a lot of poly-drive producing well well-flushing pressure energy and reach more than the 10MPa, and mostly the normal well-flushing task of constituent parts is to be with heat to wash pump with the station, by pipeline delivering hot water well-flushing.Heat is washed the pump output pressure to this well-flushing, pipeline bears many-sided impacts such as pressure owing to being subject to, and heat is washed pressure and can only be guaranteed about 4MPa.Do not reach the requirement of 10MPa at all, and continuous expansion and the popularization of recovering the oil along with polymer injection, the popularization of the new technologies such as screw pump oil production, so that the problem of down-hole pump barrel interior spatial structure is blocked up well easily, this kind well-flushing mode can not satisfy finishing smoothly of current well-flushing task more far away.The well-flushing task that can't finish just cooperates tank car to finish with the high pressure cement car, has therefore caused again a series of problem.
At first, cost issues, the well-flushing cost is high.Well-washing truck is main equipment, goes out the well-flushing task one time, and two chassis must go out simultaneously, during fuel consumption, deckhead student contributions pooled to pay for class activities with the above labour cost of, five people, add water rate and use etc., cause the overall cost of well-flushing too high.By a machine-team 8 hours, can only finish the well-flushing task of 2 ~ 3 wells.Various expense summations are but up to units up to ten thousand.The second, the equipment maintenance and management difficulty is large, and equipment is relatively less, and calling needs higher level department Unified transfers, causes well-flushing work limitation sexual deviation, and a lot of wells are to time between well-flushings, but can not in time obtain processing, and impact is normally produced.The 3rd, require comparatively strict to field ground, road surface.In rainy season, because well site or drifting road mostly are mud ground, cementing truck and tank car deadweight are excessive, are easy to be embedded and can't travel.Cause can't well-flushing situation.The 4th, tank car adds water and must arrive water point and add water, distance back and forth, comprises all in vain the wastes of time that add water, has reduced operating efficiency.Therefore, a kind of simple in structure, easy to use and can satisfy the well-washing truck of oil field needs in the urgent need to developing for the present well-flushing difficult problem in oil field.
Summary of the invention
The purpose of this utility model provides a kind of oil field special high-pressure well-washing truck, solves present oilfield well cleanout truck because equipment is huge, uses inconvenience, can not dredge at any time the problem of stifled well.
The utility model is achieved through the following technical solutions: oil field special high-pressure well-washing truck, this device comprises wagon box, comes water pipeline, water storage flume, plunger type injection pump, motor, water outlet pipeline, wherein, come water pipeline, water storage flume, plunger type injection pump, motor, water outlet pipeline to be installed on the wagon box, the input of water storage flume is connected with coming water pipeline, output connects the plunger type injection pump, on the plunger type injection pump motor is housed, plunger type is injected delivery side of pump and is connected the water outlet pipeline, and the water outlet pipeline is provided with ball-and-seat.
Adopt the good effect of technique scheme: the utlity model has following advantage:
The first, reduced various expenses.The power of this device has so just reduced a large amount of fuel consumptions than before from aboveground supply of electric power, has reduced expense; This well-washing truck connecting line is light, and convenient operation just can be operated by electrician and another well-flushing worker two people, has saved than before three personnel and has dropped into, and has reduced labour cost; Because this equipment manufacturing cost is low, squad can directly be equipped with, and namely can save the One-Shift Costs of making cementing truck and tank car; This equipment is to adopt individual well heat to wash pipeline to supply water, utilization be recirculated water in the station, therefore reduced the water expense of going out to add water;
The second, full oil recovery factory cementing truck limited amount can't in time mate when the well-flushing task is arranged.Also can delay duration of well flushing, miss best well-flushing opportunity.The design of this device is all well washing equipments to be positioned in the trailer bucket fix, and car load is light, and flexibly, cost is low, is convenient to each squad of basic unit and is equipped with, and uses at any time;
The 3rd, therefore cementing truck, tank car can delay much normally well-flushing tasks because from great, when muddy such as the rainy day road, well-flushing work is finished at the scene that can't enter, and misses best well-flushing opportunity, brings a lot of contingency questions.And this apparatus structure is simple, and is lightweight flexibly, and by the large rubber tire traction that each squad has, it is on-the-spot to arrive at any time any one well-flushing, finishes the well-flushing task;
The 4th, former washing/cleaning equipment needs tank car to arrive at a distance to beat hot water, and expense is large, length consuming time; And this device is furnished with water storage flume, and hot water is taken from the heat of individual well and washes the interior station water supply of pipeline, and water intaking is convenient, saves time, and does not involve any surcharge.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure, 1 wagon box, 2 come water pipeline, 3 water storage flumes, 4 plunger type injection pumps, 5 motors, 6 water outlet pipelines, 7 ball-and-seats.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is structural representation of the present utility model, as shown in the figure, oil field special high-pressure well-washing truck, this device comprises wagon box 1, comes water pipeline 2, water storage flume 3, plunger type injection pump 4, motor 5, water outlet pipeline 6, wherein, come water pipeline 2, water storage flume 3, plunger type injection pump 4, motor 5, water outlet pipeline 6 to be installed on the wagon box 1, purpose is so that car load is light, flexible, reduces cost.Water storage flume 3 is used for storage hot water, and the input of water storage flume 3 is connected with coming water pipeline 2, and output connects plunger type injection pump 4.Come water pipeline 2 to be used for washing pipeline with the heat of individual well and be connected, hot water can store by coming water pipeline 2 to enter water storage flume 3, enters plunger type injection pump 4 again and pressurizes.Motor 5 is housed on the plunger type injection pump 4, and the output of plunger type injection pump 4 connects water outlet pipeline 6, and water outlet pipeline 6 is provided with ball-and-seat 7.Motor 5 connects power supply in use, is used for actuation plunger formula injection pump 4, and after the pressurization through plunger type injection pump 4, hot water enters by water outlet pipeline 6 and carries out clean-out service in the well, and ball-and-seat 7 is used for control water (flow) direction and speed.
During use, this device is transported into the oil district, in the future water pipeline 2 is washed pipeline with the heat of individual well and is connected, and water outlet pipeline 6 accesses in the wells, motor 5 connecting well power sources, open motor 5, actuation plunger formula injection pump 4, hot water enters water storage flume 3 through the water pipeline 2 of coming, and enters plunger type injection pump 4, through plunger type injection pump 4 suppress effect after, high-pressure water heating enters through water outlet pipeline 6 and carries out clean-out service in the well.This device well-washing truck is before compared, and is simple in structure, easy to use, can greatly reduce the cost of oil field operation, overcomes the in the past problems of well-flushing, is suitable for the large scale application in oil field.
