Description
Technical field
The invention relates to a kind of liquid automatic on-line metering device, is used in oil well or coal bed gas well scene, for measuring the device of low discharge, unstable fluid automatic on-line flow.
Background technology
Liquid flow measuring method in the market mainly contains two kinds, water meter and flow meter, but at some special dimensions, (such as: output liquid of coal bed methane well metering aspect) is not all applied very well.Main cause is: water meter runs into gassiness in coal dust impact, water, and test error is very large; Flow meter when weep and when the aquifer yield of coal bed gas well is very little measuring accuracy cannot ensure.
The automatic equipment of the little water yield of current domestic coal bed gas field proper measurement is also in blank.
The main component of output liquid of coal bed methane well body is water, also containing a small amount of coal dust and gas, the operation initial stage is also containing some fracturing fluids, coal dust and the accuracy of measuring of gas on liquid have larger impact, especially for the well that some aquifer yields are less, because the aquifer yield of every day is very low, only have a few side, even only to produce the water less than 1 side every day at some block many wells.For the way that the production fluid automatic gauge of these wells is at present also not good, can only rely on and manually utilize measuring cup to keep watch to measure an aquifer yield in well head dozens of minutes.Inefficiency, can not meet the on-the-spot needs of digitlization.
Usually, when aquifer yield is larger, general coal bed gas well scene adopts fluid flowmeter or electronic water meter, and the subject matter that this method of measurement exists has:
1, coal dust can be attached on the impeller of flow meter, because the normal rotation affecting impeller causes metering inaccurate;
2, gas is that minute bubbles state and liquid are together discharged to ground by compressing in stratum, bubble from shaft bottom earthward flow process because the pressure be subject to constantly reduces, bubble volume can constantly increase, when after the process pipelines of arrival ground, Pressure Drop is to minimum, the volume of gas also reaches maximum, and gas at this moment and liquid can present the nowed forming such as slug flow or stratified flow in pipe.Which kind of nowed forming all can affect the measuring accuracy of flow meter due to the existence of gas widely, thus causes the degree of accuracy of liquid meter to go wrong;
3, when the amount of production fluid is less, the liquid level in ground survey pipeline section can lower than the impeller of measuring equipment, although at this moment there will be the situation having liquid to flow through impeller not rotate.
The appearance of above-mentioned situation not only can affect the accuracy of measuring of liquid, the more important thing is that above-mentioned three kinds of situations easily cause people to judge the production status of coal bed gas well by accident, especially when the gas flow in liquid is more or Liquid output is lower, its accuracy of measurement error is larger thus cause the production status of people to coal bed gas well seriously to be judged by accident, take the tune ginseng measure of mistake, cause economic loss.Particularly for the coal bed gas well that aquifer yield is little, also there is no good self-operated measuring unit at present.
