Abstract

The invention discloses a geothermal wellhead two-phase flow dryness and flow measurement system. The system comprises a temperature measurement line, a temperature measurement fixing pipe, a submersible pump, a pump pipe, a well pipe, a pressure gauge, a gas-liquid separator, a steam pipeline, a temperature measurement device, a flow meter and a liquid pipeline, wherein the temperature measurement fixing pipe is put into the well pipe along the wall of the well pipe; the temperature measurement line is fixed on the temperature measurement fixing pipe and is put into the well pipe along the temperature measurement fixing pipe; the submersible pump is positioned below the liquid level in the well pipe; one end of the pump pipe is connected with the submersible pump, and the other end of thepump pipe is connected with the gas-liquid separator; the upper part of the gas-liquid separator is connected with the steam pipeline, and the middle position of the gas-liquid separator is connectedwith the liquid pipeline; the temperature measurement device is connected to the liquid pipeline; and the gas-liquid separator and the liquid pipeline are positioned on the ground surface. Accordingto the measurement system, the wellhead gas-liquid separator divides two-phase flow into steam and liquid, the flow of the liquid is measured through the flow meter, and the dryness of the two-phase flow is calculated through the temperature below a flash point and the temperature of the ground surface liquid pipeline; and the measurement system is simple in structure, easy to operate and low in development and maintenance cost.

Description

technical field [0001] The invention relates to the technical field of geothermal development and utilization, in particular to a geothermal wellhead two-phase flow dryness and flow measurement system. Background technique [0002] my country is rich in geothermal resources. The development and utilization of geothermal energy for power generation and heating can increase the proportion of renewable energy in my country and play an important role in alleviating smog. In the process of geothermal development and utilization, it is very necessary to clarify the flow rate and dryness of the geothermal fluid at the wellhead, which can provide a scientific basis for the determination of the subsequent development and utilization scale, installed capacity and heating area. At present, the test equipment for the flow rate and dryness of gas-liquid two-phase flow is relatively complicated and expensive, and is not suitable for the low-profit geothermal field.
