Description
Technical field
The utility model relates to the simple and easy oil-withdrawal water-injection metering device that in a kind of oil exploitation process oilwell produced fluid amount, gas production, water injection well injection rate is measured.
Background technology
At oil recovery, water injecting metering station that early eighties, mid-term go into operation, the operation through more than 20 years progressively enters regeneration period, because of these stations go into operation initial stages with compare at present, the oil field background difference is huge, now will be updated to which type of oil recovery, water filling multi-purpose station, has following problem to research and solve:
The initial stage of building a station single station daily oil production reaches 150-300t, and the single seat measuring station is equipped with tens people, under the abundant background of output height at that time, administrative staff, has built that function is more complete, big (the about 100m of area of construction scope
2), the oil recovery of cost height (700,000 yuan /), water filling associating measuring station.And our factory list station daily average oil production has been reduced to 19.2t at present, eight to 1/10th of the first level of only building a station, and single station personnel configuration has only 2-3 people, just builds a station 1/5th of the initial stage.At this moment, as also upgrading oil recovery, water filling associating measuring station, will bring two problems by former scale, proterotype:
(1) dispose excessive because of oil recovery, water filling associating measuring station, have only tens tons level with respect to present single station daily oil production, the measuring station cost is too high, list is stood running cost height (ten thousand yuan/year of 15-17), oversize problems such as (1-2 hours/well) of metering time is very outstanding.
(2) proterotype recovers the oil, the scale of water filling associating measuring station is big, and management workload is many, and single at present station configuration personnel are few, causes per capita that workload increases considerably, and management difficulty strengthens.
Therefore, the pattern of present newly-built oil recovery, water filling associating measuring station, will be according to existing single station, oil field daily oil production, single station personnel's configuring condition, and follow the principle of " building major station when output is high; build simple and easy station when yielding poorly ", still, build which type of simple and easy oil recovery, water filling associating measuring station, do not have unified standard, be without a fixed pattern yet.
Address the above problem, just must development and Design go out to be fit to simple and easy oil recovery, the water filling associating measuring station of oil field present situation, simultaneously, also former oil recovery, water filling will be united " five is big " problem of measuring station existence: big house (100m
2), big eliminator (800 type eliminator), (60-80m is joined at single station to big oil tank
3Big oil tank), large power, electrically insulation (prevent winter manifold from freezing join the 10-12KW electric heater), metering time oversize (40 minutes to 1 hour), solve together.
The utility model content
The purpose of this utility model is the simple and easy oil-withdrawal water-injection metering device that development and Design goes out that cost is low, operating cost is low, the metering time is short, easy to operate.
Simple and easy oil-withdrawal water-injection metering device described in the utility model is realized by following structure:
It is made up of oil well measurement pipe, running water pipe, commentaries on classics oil tank, commentaries on classics oil pump, eliminator, incubator, content gauge, gas meter, electronic flow instrument, safety valve, control valve, control valve, three way cock and straight-through valve.The single-well oil-mining pipeline that is connected with oil well, be connected with a triple valve inlet end, be connected with a straight-through valve inlet end by three way cock one port of export, the straight-through valve port of export is connected with the pipeline that deoils, another port of export of three way cock is connected with the oil well measurement pipeline, one end of oil well measurement pipeline is connected with separator inlet, separator outlet is connected with a triple valve inlet end, another arrival end of three way cock is connected with an end of gas meter, the other end of gas meter is connected with eliminator, the three way cock port of export is connected with the pipeline that deoils, content gauge is positioned at the outer side-lower of eliminator, and the other end of oil well measurement pipeline is connected with commentaries on classics oil tank inlet by a straight-through valve, changes oil tank outlet and commentaries on classics oil pump, after one straight-through valve connects, be connected with the pipeline that deoils by straight-through valve, safety valve is positioned at top, the eliminator outside; Tap water pipeline connects control valve, electronic flow instrument, water regulating valve successively, is connected with the water injection well pipeline, and the said equipment is contained in the incubator.
The flow process of simple and easy oil-withdrawal water-injection metering device can be divided into by duty, the flow process of (well is in the metering state all the time), washing pipe line states flow process when oil well does not measure state flow journey, oil well measurement state.Below will discuss respectively the operating principle of above-mentioned flow process.
Flow process when simple and easy oil-extracting and water-injecting 2220.-metering device does not measure state, the oil well gas-liquid mixture fluid enters through single-well oil-mining pipeline, enters gathering line through three way cock, straight-through valve.The injection water that comes tap water pipeline through control valve, electronic flow instrument, water regulating valve, enter the water injection well pipeline, because of the water that injects well obtains metering by the electronic flow instrument.
When needs measured single oil well, by the three way cock switching flow, the gas-liquid mixture fluid of this well entered in the 400 type eliminators, and liquid is owing to be sunken to the eliminator bottom under the effect of gravity, and its liquid level can show by content gauge; Enter the interior liquid measure of eliminator in unit interval as calculated again, can obtain the well daily fluid production rate.Enter the gas of eliminator because density is little, the top outlet by eliminator enters the gas meter metering, can obtain this well daily output tolerance as calculated.As also measuring other well, the oil pressure in the eliminator can be gone out, this number well is switched to production status after, again other number well is switched in the eliminator.
Oil well behind the closing well, solidifies in-line in order to prevent oil well to the residual liquid in the surface line between the simple and easy metering dress in the winter time, and the liquid in it is poured to be changeed in the oil tank.Gas-liquid mixture fluid enters the commentaries on classics oil tank from gauge line (the about 0.5MPa of fluid pressure), and the natural gas body enters atmosphere from blow-down pipe.Liquid remains in to be changeed in the oil tank, and (about 0.5MPa) flows back to gauge line after gear pump boosts again, removes gathering line.
The utility model:
1, oil well measurement flow process, well flow journey have been carried out integrated design,, become intensive little cuboid flowage structure original loose long line style flowage structure.
2, the pressuring oil pipe line is designed in the eliminator bottom, make it have draining, two kinds of functions of blowdown, make eliminator need not periodical blowdown.
3, designed 2.3m
3Change the small-sized commentaries on classics oil device that oil tank and gear pump are formed, increase and change functional oil winter.
4, on the oil well measurement pipe, designed the three way cock measurement flow of corresponding one of one group of every mouthful of oil well, made gauging more convenient to operate.
(3) because the manifold of this device is shaped as the cuboid of rule, be convenient to the sealing insulation, reduced energy consumption.
(4) the one-well metering time dropped to 5-15 minute by original 40 minutes to 1 hour.
(5) the gauging operation sequence reduces 80%.
(6) replacing amounts to when closing the valve door, need not to stand full closing well, has reduced the oil well output loss.
