Description

The oil gas water three phase self-measuring device
Technical field
The utility model relates to the oil gas water three phase self-measuring device, belongs to oil-gas field development displacement test self-measuring device technical field.
Background technology
Displacement test is a kind of important method of estimating the oil and gas exploitation correlation technique, can be oil-gas field development, and improving recovery ratio provides reliable experimental technique data.In the displacement test process, measuring requirement to flow is accurate, reliable, but because most in-place oils and water and milkization, the oil phase moisture content can be up to 60%, be difficult to automatic separation, so the accurate metering of profit two-phase is a difficult problem always, many armrests are moving to separate the back metering, workload is big, and error is big.Have about the relevant patent of laboratory at present: 00105764.2 " dual liquid columns difference in height (or pressure differential) density difference oil-gas-water three-phase metering ", 00205862.6 " high accuracy full-automatic oil-air water three-phase flow meter ", 02224842.0 " high accuracy oil-gas-water three phase flow quantity automatic gauge instrument ", 03232912.1 " differential full-automatic oil-air water three-phase flow meter " with the oil gas water three phase automatic gauge.Wherein, patent 00205862.6,02224842.0 and 03232912.1 all is to be separated into the basis automatically with the profit two-phase, only is applicable to minority formation oil and simulated oil; Patent 00105764.2 adopts dual liquid columns difference in height or pressure differential and profit density contrast to carry out the profit two-phase flow measurement, but dual liquid columns difference in height, pressure differential certainty of measurement are low, and error in dipping is big.
Summary of the invention
The utility model purpose is influenced by profit two alternate phases at the measuring accuracy that prior art exists, certainty of measurement is low, the defective that error in dipping is big provides the displacement test oil gas water three phase self-measuring device of a kind of high accuracy, full-automatic continuous metering flow.
The utility model is made up of gas flowmeter, magnetostrictive liquid level sensor, balance, hopper, computer, offer first through hole and second through hole on the side pipe wall of gas-liquid separation tube respectively, wherein second through hole is connected with gas flowmeter by pipeline, gas-liquid separation tube upper end is connected with magnetostrictive liquid level sensor by internal thread, and the lower end is sitting on the platform; Gas flowmeter, magnetostrictive liquid level sensor and balance are connected with computer by data wire respectively.
The utility model metering result is not subjected to the influence of profit two alternate phases, can significantly improve measuring accuracy, enlarges the scope of application, and final data accurately, reliably.

Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1, the utility model is made up of gas flowmeter 1, magnetostrictive liquid level sensor 2, balance 3, hopper 4, computer 7, have first through hole 5 and second through hole 6 on the side pipe wall of gas-liquid separation tube 4, second through hole 6 is connected with gas flowmeter 1 by pipeline, gas-liquid separation tube 4 upper ends are connected with magnetostrictive liquid level sensor 2 by internal thread, and the lower end is sitting on balance 3 weighing plates; Gas flowmeter 1, magnetostrictive liquid level sensor 2 and balance 3 are connected with computer 7 by data wire respectively.
When carrying out indoor dynamic displacement test, the displacement fluid enters hopper 4 by through hole 5, and gas enters gas flowmeter 1 metering by through hole 6; Liquid gross mass in the balance 3 weightometer graduated cylinders 4; Magnetostrictive liquid level sensor 2 is measured total liquid volume in the hopper 4; Computer 7 is gathered the liquid gross mass of balance 3 weighings and the total liquid volume data that magnetostrictive liquid level sensor 2 is measured, by the following profit two-phase volume flow that calculates.
Known: the density of oil and water is ρ oAnd ρ w,
Total liquid volume V, gross mass m in the testing time t
Suppose that the water volume that flows into is V w, the volume of oil is V oSo, have:
V=V w+V o………………………………(1)
