The bottom part of the measurement tank is provided with a liquid discharge valve and a dirt discharge valve, the upper part of the measurement tank is provided with an electricity telemetering gas rotary flowmetre, an air evacuation valve, a magnetic telescopic level meter, a pressure transmitter, a safety valve, a temperature sensor, an inflow valve and a bypass valve. The utility model has the advantages of simple structure, convenient use, no oil-water separation device in the measurement tank, no need of manual interruption, good stability and continuous on-line operation for a long time; the acquisition and the control of all the signals are automatically carried out by a controller.
Description
Technical field
The utility model relates to the oil gas water flow self-measuring device, relates in particular to a kind of oil well oil-gas-water three phase flow quantity self-measuring device.
Background technology
In the prior art, the metering of oil, gas, water adopts triphase separator to separate mostly in the crude oil, the oil emulsion of separating, free water and natural gas via pipe system separately, after the metering of measure monitor instrument, pool together again, enter external transport pipeline together without metering oil well three-phase mixture with other.This method automaticity is low, and metering cycle is long, investment is big, system maintenance is complicated.Though the existing online three-phase flow meter of minority, measuring accuracy is low, and long term reliability is poor.
Summary of the invention
The purpose of this utility model provides a kind of oil well oil-gas-water three phase flow quantity self-measuring device.
It has test tank, the test tank both sides are respectively equipped with glass tube, differential pressure transmitter, the test tank bottom is provided with tapping valve, blowoff valve, and test tank top is provided with electrical distance transmitting gas rotameter, vent valve, magnetostriction liquidometer, pressure unit, safety valve, temperature sensor, valve and bypass valve become a mandarin.
The utility model is simple in structure, no any oily-water seperating equipment in the test tank; Easy to use, all signals collecting and control automatically perform by controller, need not manual intervention; Good stability, on-line continuous operation for a long time.
Description of drawings
Accompanying drawing is an oil well oil-gas-water three phase flow quantity self-measuring device synoptic diagram.
Embodiment
Oil well oil-gas-water three phase flow quantity self-measuring device has test tank 1, the test tank both sides are respectively equipped with glass tube 2, differential pressure transmitter 5, the test tank bottom is provided with tapping valve 3, blowoff valve 4, and test tank top is provided with electrical distance transmitting gas rotameter 6, vent valve 7, magnetostriction liquidometer 8, pressure unit 9, safety valve 10, temperature sensor 11, valve 12 and bypass valve 13 become a mandarin.
Controller output signal is opened the valve 12 that becomes a mandarin allows crude oil enter test tank 1, and picks up counting, and controller is by gathering liquid level and differential pressure value in the test tank in real time.When liquid level reaches setting value, close the valve 12 that becomes a mandarin, open bypass valve 13, stop timing simultaneously.Treat to calculate according to the reading of liquid level gauge and differential pressure gauge behind the level stability volume and the density of crude oil, calculate the oil in the crude oil and the content of water by given formula then, utilize timing value to calculate the flow separately of oil and water in the crude oil at last.Controller is by the force value in the collection test tank, and the Kai Heguan of control vent valve 7, keeps a jar interior constant pressure.A gas meter is installed in back at vent valve 7, measures the flow of gas.Thereby finish the automatic gauge of oil, gas, water three-phase flow.Pressure after once metering is finished in the jar can make crude oil wherein discharge smoothly.
The utility model is to utilize the altitude gauge of interior differential pressure of test tank and jar interior liquid level to calculate a jar interior oil and a liquid water content, utilizes gas meter to measure the flow of rock gas then.Calculate the flow separately of oil in the crude oil, gas, water in conjunction with the timing value of controller.
High-precision magnetostriction type liquid level gauge is adopted in the measurement of liquid level, and the level gauging precision can reach 0.02%F.S, can select the float of corresponding density as requested for use, to satisfy the measuring requirement of different densities crude oil.The electrical distance transmitting double flanges differential pressure transmitter of high precision, high stability is adopted in differential pressure measurement, and enclosed construction is adopted in the transmission of pressure at two ends, can avoid crude oil to enter inner formation of transmitter and stop up, and improves the reliability of measuring apparatus.
The measuring principle of three-phase flow is as follows:
The liquid level h that utilizes the magnetostriction type liquid level gauge to record can calculate the cumulative volume V of crude oil
V＝C·h (1)
C is the volume factor of test tank in the formula, is obtained by demarcation.
The differential pressure value Δ p that utilizes differential pressure transmitter to record then calculates the hybrid density ρ of crude oil
Because
