The automatic liquid level metering device is characterized in that: the upper part and the lower part of the glass liquid level meter are respectively provided with a photoelectric sensor A and a photoelectric sensor B, and the photoelectric sensor A and the photoelectric sensor B are respectively connected with a signal acquisition and control unit. The automatic liquid level metering device solves the problem that the traditional metering mode has low measuring precision; and since the photoelectric sensors are used as core detection parts, the stability and the working reliability of the product are greatly improved relative to an electrode detection mode. The automatic liquid level metering device is especially suitable for the later stage of the oil-field development and occasions where the gas quantity is low during single-well metering and intermittent oil can not be metered in the oil well. The utility model has the advantages of simple structure, low transformation cost, short transformation period and wide application range and benefits to be popularized and applied.
Description
Technical field
The utility model relates to a kind of oil field metering device, specifically is a kind of oil well liquid measure self-measuring device, and it is mainly used in the petroleum metering station, calculates the production fluid amount of oil well automatically.
Background technology
In the petroleum metering station, major part all adopts eliminator that individual well output liquid is carried out the gas-liquid two-phase separation at present, and gas, liquid carry out constant volume metering respectively, convert out one day liquid measure and tolerance with the continuous data of short time.Need of the variation of gauging workman scene, use hand-timed mode, obtain time quantum, and then the time quantum of obtaining is inserted in to convert in the special-purpose formula obtains the production fluid amount and the gas production of oil well by the sight glass pipe page.In this process, the gauging workman also needs the different conversion valve of frequent operation to finish the measurement of liquid measure and tolerance.
This kind oil well measurement method can be finished metering task to the oil well output object in early days in oil field development, at the oil field that enters the middle and later periods exploitation, because water content increases in the extraction liquid, gas content descends, and has low liquid measure simultaneously, intermittently goes out the wet goods reason, this kind metering method has been difficult to reach desired measuring accuracy, caused individual well crude output error in dipping big, workload is big, and efficient is low; Bring a lot of difficulties to examination of well station and the evaluation of single well measure implementation benefit, strengthened the management difficulty.
The integral body that adopts is transformed the mode of measuring station and eliminator, and complex process costs an arm and a leg, and disposable input cost is too high, and the retrofit work amount is big, and the cycle is long, and the scope of simultaneous adaptation is also narrower, is unfavorable for large-scale promotion.Therefore domestic measuring station oil well measurement mainly still adopts traditional eliminator to carry out the mode of gas-liquid metering.
Summary of the invention
In order to address the above problem, reach and alleviate tank strapper people workload, to increase work efficiency and the purpose of certainty of measurement, the utility model provides a kind of oil well liquid measure self-measuring device.
The utility model implementation is as follows:
A kind of oil well liquid measure self-measuring device, comprise eliminator, eliminator is provided with gauge glass, it is characterized in that, in the upper and lower of gauge glass photoelectric sensors A and photoelectric sensor B are set respectively, photoelectric sensors A is connected with control module with signals collecting respectively with photoelectric sensor B.
Further, be provided with metering valve external transport pipeline and metering header in both sides, eliminator top, the metering valve external transport pipeline is connected by pipeline with the metering header, bottom at eliminator also is provided with single-well oil-mining pipeline, be equipped with the electronics valve on above-mentioned pipeline, each electronics valve is connected with control module with signals collecting.
Traditional gauging process is to install on the gs-oil separator about a long 90cm and constituting the gauge glass of communicating pipe with eliminator, in the eliminator oil of constant weight with hydraulic pressure in glass tube, obtain the weight of oil in the eliminator according to the relation of oil mass in the height of liter waterborne in the glass tube and the eliminator, record the needed time of liquid level lifting height in the glass tube thus, can convert fuel-displaced well yield.
Detection transducing part in this device is made up of two photoelectric sensors, and the B position is called for short in a bottom that is positioned at the liquid level of gauge glass regulation; The A position is called for short on a top that is positioned at the liquid level of gauge glass regulation, in the gauging process, when the oil in the eliminator with during hydraulic pressure is in the glass tube, when the liquid level of glass tube reaches the B position, first group of electric light hair goes out the signal of telecommunication and gives collection and processing unit, timer in collection and the processing unit picks up counting, when the liquid level of glass tube reaches the A position, second group of electric light hair goes out the signal of telecommunication and gives collection and processing unit, timer in collection and the processing unit stops timing, and, calculate the liquid outlet quantity of oil well in the unit interval automatically according to the mode of operation that configures in advance.After measuring one group of data, according to previously selected mode of operation, processing unit can send control instruction, and control electronics valve carries out liquid capacity metering next time according to working flow, by repeatedly measuring, reaches the purpose that improves certainty of measurement.The data of surveying can upload to preservation processing in the specified server by wireless network as required, when bringing convenience to statistical department, also make things convenient for the manager to grasp the firsthand information.
Compared with prior art, the utility model has the advantages that:
The utility model has solved in the conventional metered dose mode, and the problem that certainty of measurement is low adopts the test section of photoelectric sensor as core, with respect to the mode that adopts electrode detection, has improved the stability and the functional reliability of product greatly.Be particularly useful for latter period of oilfield development, the air content that runs in the one-well metering process is low, intermittently the unmeasurable occasion of fuel-displaced oil well.Device is constructed simply, and improvement cost is low, and the transformation cycle is short, and is applied widely, helps applying.
