Oil and water two-phase metering device

Abstract

The invention provides an oil and water two-phase metering device which comprises a microcomputer (1), a bottom plate (2), a thermostat (3), an oil and water separation part, a high-pressure window part, an oil volume metering part and a total volume metering part, wherein the oil and water separation part, the high-pressure window part and the oil volume metering part are arrayed linearly in sequence, arranged on the bottom plate (2) and placed in the thermostat (3). The device achieves separated metering of an oil and water mixture during a scientific research experimental process of an oil field, and measurement of the instantaneous flow rate and accumulated flow rate of the total volume of the oil and water mixture on line at high temperature and high pressure, and the instantaneous flow rate and accumulated flow rate of oil and water; the device and a front end experimental model can be placed in the same temperature field; the distance between the metering device and the experimental model is shortened to the greatest extent; and a reliable method is provided for reflecting states of the oil and the water in the model more precisely and timely.

Description

technical field [0001] The invention relates to an oil-water two-phase metering device, which belongs to the technical field of petroleum instruments. Background technique [0002] In the process of oilfield scientific research, high-precision oil-water metering devices are required. The existing oil-water metering devices mainly include the following two types: [0003] 1) if figure 1 As shown in the oil-water metering device, the oil-water mixture to be tested is put into the metering tube, and the oil remaining in the tube is measured by discharging the pre-injected water. The device has the following defects: A) the glass tube is not pressure-bearing; B) the scale is thick, and the oil volume can only be read manually, and the oil-water interface is unclear and cannot be read; C) the distance between the oil-water interface and the oil-water mixture to be measured enters the metering tube entrance Long, the oil-water mixture to be tested cannot reach the oil-water ...

Problems solved by technology

The device has the following defects: A) the glass tube is not pressure-bearing; B) the scale is thick, and the oil volume can only be read manually, and the oil-water interface is unclear and cannot be read; C) the distance between the oil-water interface and the oil-water mixture to be measured enters the metering tube entrance Long, the oil-water mixture to be tested cannot reach the oil-water interface in time, and the oil volume response lags behind

The device has the following defects: A) the glass tube is not under pressure; B) the electrode is easily contaminated by oil, causing misjudgment; C) the instantaneous flow rate cannot be measured; D) the oil-water mixture is discharged from the model to the oil-water metering device, and then to the oil and water pump Suction metering, the pipeline is too long
