Description
Technical field
The utility model relates to the downhole operation equipment of petroleum industry, particularly workover fluid rapid extraction uses system, be applicable to rapid extraction workover fluid in the oil well operation of nearly water injection well, also can be arranged between cementing truck and operation wellhead simultaneously, quickly through cementing truck by under the workover fluid Injection Well in tank car, simplify the erection procedure of operation wellhead injection manifold.
Background technology
Oil field development enters the middle and later periods, and pipe string of oil-water well corrosion and scaling eccentric wear degree is serious, and unconsolidated reservoir sand production in oil is serious, and the quantity of heavy oil wells, inclined shaft, low yield inefficient well and ratio increase, and cause judging complicated to the hole condition of abnormal well.Judge whether pumpingh well tubing string misses at present, well tail pipe whether sand plug and the oil reservoir method whether sand buries be fetch water in sleeve pipe or oil pipe with cementing truck and tank car, suppress according to it situation that builds the pressure and judge it is direct and the most the most frequently used method.There is following problem in this determination methods of squeezing in oil-water well pressure testing examination:
One be deep-well, the work operations amount ratio of inclined shaft increases, the workloads such as well-flushing in operation process, examination squeeze, sand washing, pipe string pressure test strengthen.
Two is the workover fluids squeezed for pressure testing examination, need from the roping of disposing polluted water in oil station, and the sewage that Sewage Disposal is released, unclean, road is far away, and in way, effluent stream is spilt and caused environment pollution.
Three is send the tank car usage quantity of workover fluid many for pressure testing examination pultrusion, and the stand-by period is long, and the operation that well head installs injection manifold is wasted time and energy, and expense drops into high.
Four are oil-water well well-flushings, down-hole string pressure testing, oil reservoir examination squeeze, also have the residue sewage in operation in the equipment such as preventer used and oil pipe plug valve to want secondary emission, the sewage be disposed in circulatory pool cannot process, contaminated environment.
The transportation problem of workover fluid and workover fluid is all related to the pollution problem of environment in the determination methods that above-mentioned oil-water well pressure testing examination is squeezed.Special vehicle configures less, it is nervous to use, put in place not in time, and the stand-by period is long, the outstanding problem that freight charges are high.The sealing pressure testing of the equipment such as well in operation completion tubular column, preventer, oil pipe plug valve, all adopts the mode of tank car, cementing truck pressure testing, and pressure testing costly, also delays production because not ensureing the time of using cars even sometimes.Water source distance, sewage is unclean can polluted reservoir.Unclean in tank car, foreign material enter well can block oil reservoir, and foreign material enter pump and pump can be caused to leak, and operate dangerous.When tank car well-flushing water supply volume is large, water treatment costly etc., all causes operating cost to remain high.In above-mentioned underground work, the extraction of workover fluid uses problem to need to improve.
Summary of the invention
The purpose of this utility model is to provide workover fluid rapid extraction and uses system, when closing on the oil well operation of water injection well or water filling main line, solution workover fluid draws and send and use problem, also solves the installation question of well head injection manifold when using tank car and cementing truck operation simultaneously.Reduce the oil well operation cost closing on water injection well, reduce the underground work workload that oil-water well is squeezed in pressure testing examination, alleviate the working strength of worker.
Technical solution of the present utility model is: workover fluid rapid extraction uses system to comprise application pipeline and re-injection pipeline, tandem pipeline between application pipeline and re-injection pipeline is equipped with application controls valve and re-injection by-pass valve control, extract on pipeline and flow meter and pressure meter are housed, this extraction pipeline one end and the tandem pipeline connection between application controls valve and re-injection by-pass valve control, the other end is connected with water injection well threeway; Re-injection pipeline is equipped with water jet pump, re-injection joint and re-injection high-pressure hose, re-injection high-pressure hose is connected with the sleeve valve of oil well; Application pipeline is equipped with safety valve, apply filters, pressure regulator valve and applying high voltage flexible pipe, applying high voltage flexible pipe is connected with four-way connection and application tool successively.
Remarkable result of the present utility model is: in the oil well operation closing on water injection well, and inactive tank car draws and send, transports sewage.Utilize well group to close on well or water filling main line high-pressure sewage as water source point, the cost of transportation of workover fluid can be reduced.Water source point high-pressure sewage, after step-down filtration treatment, can be used for cleaning downhole tool, and the operations such as liquid are filled with in down-hole string pressure testing, well control.Oil well casing can be entered after waste water in above-mentioned use processes after filtration or enter petroleum pipeline and reclaim, also can be used for cleaning well head.When operation oil well is away from water injection well or water filling main line, the injection manifold that native system can replace former well head to install, under fast the workover fluid in tank car being passed through cementing truck Injection Well, simplifies well head erection procedure.Underground work uses the waste liquid in Posterior circle pond the clean sewage after filtering can also be injected oil well casing or enter petroleum pipeline by the jet pump in native system, re-injection high-pressure hose and reclaims.
In sum, the utility model changes water source point, significantly reduces the cost of transportation of workover fluid.Instead of, with cementing truck and tank car, envelope and the crowded de-plugging of oil reservoir examination are tested to tubing string, not only save cost of transportation, also can judge operating mode fast, shorten and stop the well time, improve and hold up well efficiency.Avoid the adverse consequences brought because sand setting sand plug, shaft bottom sand plug, oil layer blocking and feed flow are not enough simultaneously, improve pump efficiency, reduce failed well number amount, thus also reduce upkeep operation cost.Native system manufacture is simple, and small in volume is easy to loading and unloading, safe and reliable, is conducive to reducing worker's labour intensity.Easy and simple to handle, pressure test pressure is high, improves operation timeliness.Achieve cleaner production, waste liquid filtered and recycled is not landed, and protects environment.There is good result of use and good economic benefit.
