Problems solved by technology

In addition to the high cost, labor and time-consuming of these three methods, these measurement methods are all indirect measurement and cannot achieve real-time online detection
In particular, the separate metering of gas and liquid is more complicated and the operation process is cumbersome.

Abstract

The invention relates to a special gas, oil and water flowmeter for a pumping unit and a flow calculating method. The special gas, oil and water flowmeter for the pumping unit comprises a one-way valve, a double three-way valve, a volumetric flowmeter, a pressure sensor, an eddy current sensor, an oil-water proportional sensor and a controller, wherein the one-way valve is connected with the double three-way valve; a port A of the double three-way valve is connected with a port C of the volumetric flowmeter; a port B of the double three-way valve is connected with a port D of the volumetric flowmeter; the eddy current sensor is connected with the one-way valve; the volumetric flowmeter is respectively connected with the eddy current sensor, the pressure sensor and the oil-water proportional sensor; and the controller is respectively connected with the eddy current sensor, the pressure sensor and the oil-water proportional sensor. By the special gas, oil and water flowmeter for the pumping unit and the flow calculating method, gas flow, oil flow and water flow can be measured and calculated uniquely. The special gas, oil and water flowmeter for the pumping unit is matched with an intelligent controller and a remote background system, is small in size, simple in structure, convenient to operate and low in construction cost, runs reliably, and is a real-time online measurement metering device which is urgent in oil exploitation at present.

Description

technical field [0001] The invention relates to a novel gas, oil and water three-phase flow meter and flow calculation method specially used for pumping units. Background technique [0002] The single well metering in my country's current crude oil production process is still in an embarrassing situation where the technology lags behind the production needs. The current main measurement method is the metering station measurement method: build a station, install a large metering tank, connect more than a dozen wells to the large tank through pipes and valves, adjust the valve to connect to a certain well, and observe the time when the large tank is full , so as to convert and determine the production of the well. Flow metering vehicle metering method: Every once in a while, the metering car goes to a certain well, and within the specified time, puts the produced gas and liquid into the tank of the metering car, and separates the gas and liquid by the method of gas and liquid...
