Background

In oil exploration and development and well intervention, one must have an accurate qualitative and quantitative determination of formation production. Since oil, gas and water are generally mixed underground, and some of them are at high pressure, they must be separated and metered separately after they are flushed out. In addition, a liquid storage tank of the hydraulic pump also needs to monitor the liquid level in real time.

The ground measurement is to separate the stratum produced fluid gushed from the well by means of ground measurement equipment, record the parameters of pressure, temperature, physical property and the like of the stratum fluid, measure the respective yields of oil, gas and water respectively, take out samples for test analysis and provide important basis for the next work; the method is also an important basis for determining whether the well to be measured is put into operation, the operation mode and the facility construction scale are different and whether the well to be measured is abandoned.

The ground metering process of test oil and test production is different from the permanent production process of oil production, gas production and the like, is temporary, is easier to move and reconnect and assemble, and consists of different process units which are connected with each other, including wellhead control, heating/separating/metering, auxiliary equipment, recording instruments, safety systems, metering calibration equipment, analysis and testing, ground sampling equipment and the like. The hydraulic pump also comprises a liquid storage tank in the working process for metering and storing the working liquid.

In the process of ground measurement, a unit called a measuring tank is used for caching and settling the liquid produced by the stratum and simultaneously measuring the yield of crude oil and calibrating a liquid flowmeter. One important data for metering is the liquid level. Because the liquid comprises oil, water and emulsified components of the oil and the water, the liquid which is settled and stabilized in the metering tank can be divided into an oil layer, an emulsified liquid layer and a water layer from top to bottom, and the accurate measurement of the layered liquid level becomes the difficulty of liquid level measurement. The measurement means used at present is a traditional measurement method of a measuring fishing barrel, namely, an organic glass tube with scales is used, liquid is inserted from the top of a measuring tank or a liquid storage tank to the bottom of the tank, a valve at the bottom end of the organic glass tube is closed, the organic glass tube filled with the liquid is put out, the liquid level scale values of the interfaces of a liquid oil layer, an emulsion layer and a water layer in the tube are recorded, and the thicknesses of the oil layer, the emulsion layer and the water layer are obtained. The disadvantages of this method are: generally, two persons are needed to operate, one person supports a long organic glass tube, the other person reads and records, then a valve at the bottom end of the organic glass tube is opened, and liquid in the tube is discharged; during the operation process, both hands of a worker contact oil stains; repeated lifting and placing operations are difficult to avoid colliding, the organic glass tube is easy to damage, the valve at the bottom end of the organic glass tube is easy to lose efficacy or damage, and parts are frequently required to be maintained and replaced or a new one is purchased.

Therefore, the liquid level detection device for the oil field ground metering process metering tank is provided to solve the problems.
