Abstract
A well fluid sampling device of oil well for in the oil recovery process of petroleum. The automatic continuous sampler for oil well consists of oil-gas separating sealed sampler, valve and pipeline. The oil-gas separation closed sampler is a closed container, the closed container is provided with a shell, a partition board is arranged in the shell, and the shell is divided into an upper chamber and a lower chamber by the partition board. The clapboard is provided with clapboard holes. Well fluid may flow into the lower chamber through the baffle holes. A floating ball is arranged in the lower chamber, the liquid level of the well liquid continuously rises, and the floating ball can abut against the partition plate hole and close the partition plate hole. The upper chamber of the closed container is fixed with a liquid inlet pipeline, and the other end of the closed container is fixed on a wellhead pipeline and communicated with a flow guide pipe in the wellhead pipeline. An exhaust line is also fixed to the upper chamber of the closed vessel. A sampling valve is fixed at the lower end of the closed container. The effect is as follows: the traditional method of sampling the oil well is broken; the device also has the advantages of continuous sampling, representative obtained well fluid sample, safe operation, sampling time saving, sampling efficiency improvement and natural gas leakage reduction.
Description
Technical field:
The present invention relates to the oilfield exploitation technical field, particularly a kind of oil well well liquid sampler in the petroleum recovering process.Be a kind of sampling process automation that makes, make the well liquid sample of obtaining have more the device of representativeness, automatic Continuity.
Background technology:
At present, in the petroleum recovering process, oil well well liquid sampler commonly used is a simple sample cock.Valve is arranged on by the well head pipeline.By Artificial Control valve switch size, in pipeline, extract oil well well liquid sample, carry out the analysis of well liquid moisture content.Do not carry out the Oil-gas Separation function owing to extract the well liquid device, gas mixture from the ejection of valve sampling mouth, brings difficulty for sampling work simultaneously when extracting well liquid; At gas, oily mixing ratio height, intermittently the oil well of fluid is difficult to obtain well liquid sample in the regular hour, the sampling working time is long, also causes natural gas to leak in a large number, formation handling safety hidden danger and contaminated air, contaminated environment.In addition because manual sampling, sample time length the randomness and the unstability of produced liquid in oil well itself, the oil well well liquid sampler that makes present use, the moisture existence of the actual production fluid of moisture and oil well of obtained sample is than big-difference.Representative well liquid sample is grown, is difficult to get to the oil well sampling spended time that part producing well at intermittence or gas production are bigger.
Summary of the invention
The purpose of this invention is to provide a kind of oil well automatic continuous sampling device, Oil-gas Separation, automatic continuous sampling improve the sampling accuracy voluntarily; And can also reduce natural gas leakage, improve processing safety, save the manual sampling time, raise labour efficiency, quickly and easily oil well is carried out sampling work.Overcome the simple sample cock of tradition, by manually extracting the deficiency of oil well well liquid sample in the pipeline.
The technical solution used in the present invention is: oil well automatic continuous sampling device is made up of the airtight sampler of Oil-gas Separation, valve and pipeline.The airtight sampler of Oil-gas Separation is a closed container, and closed container has shell, and dividing plate is arranged in the shell, and dividing plate will be divided into upper and lower two chambers in the shell.The dividing plate hole is arranged on the dividing plate, and well liquid can be gone into chamber down by the dividing plate orifice flow.At the following indoor ball float that has, ball float can float on the well liquid liquid level, and well liquid liquid level continues to rise, and ball float can be butted on the dividing plate hole and close the dividing plate hole.The chamber is fixed with the feed liquor pipeline on closed container, and the other end of feed liquor pipeline is fixed on the well head pipeline, and is communicated with mozzle in the well head pipeline.On the feed liquor pipeline liquid flowing valve is arranged.The chamber also is fixed with exhaust line on closed container.Exhaust line is communicated with the well head pipeline by drain tap.Lower end at closed container is fixed with sample cock.
Described closed container is cylindric, and the top of cylinder and bottom are dome shape.
The end of the mozzle in the described well head pipeline is the inclined-plane, and bevel direction upwards makes well liquid be convenient to flow into; The well liquid that enters for mozzle has more representativeness, and is uniform porose on the tube wall of mozzle.
For ball float energy airtight baffle hole, described dividing plate hole is conical surface hole.
The principle of summary oil well automatic continuous sampling device helps to understand the present invention.The oil gas aqueous mixtures of oil well output is out-of-date from the well head pipe flow will, and some flows into mozzle, and enters on the closed container chamber by the feed liquor pipeline and carry out Oil-gas Separation, sampling automatically.The chamber is through Oil-gas Separation on closed container, and isolated natural gas is connected with well head pipeline lower position by the exhaust line that is located at the chamber, discharges separating natural gas.Do not waste natural gas, not contaminated air.The chamber is through Oil-gas Separation on closed container, and isolated well liquid is gone into chamber down by the dividing plate orifice flow.Following chamber stores well liquid sample, can open sample cock at any time, obtains representative well liquid sample.The following indoor lower ball float of density that has, chamber institute oil sample is full of instantly, and ball float is increased to the dividing plate top and is butted in the dividing plate hole under buoyancy, and the enclosed baffle hole stops the follow-up liquid that enters of feed liquor pipeline; Particularly stop sample to enter down the chamber, the accuracy of influence sampling.Secondly, a mozzle is arranged in the well head pipeline, can in well head pipe center and representative scope, take a sample, change the limitation of conventional single-point sampling from the production flow line wall, increase samples' representativeness and accuracy.When needing sample, only need to descend the liquid of chamber to be discarded to sampling bottle, be required sampling, significantly reduced natural gas leaking.Simple to operate, time saving and energy saving.
Beneficial effect of the present invention: oil well automatic continuous sampling device of the present invention can be finished oil well sampling, the particularly higher oil well of oil gas mixing ratio.Broken oil well sampling traditional method.The present invention also has continuous sampling, and the well liquid sample of obtaining is representative, and handling safety is saved sample time, improves sampling efficiency, reduces natural gas leaking.
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
