Problems solved by technology

Tarim high-pressure condensate gas well has a large gas-oil ratio (2000m 3 / t above), large oil-water density difference (nearly 0.4t / m 3 ) and other characteristics, it is difficult to obtain representative oil-water mixed samples in the existing technological process, and it is impossible to grasp the water content and change trend of a single well, and it is impossible to correctly analyze the dynamic analysis of reservoir development and timely adjust the development plan, which seriously affects the reservoir development effect and Timely supporting of oil and gas treatment system
At the same time, due to the inaccurate determination of moisture content, anti-corrosion measures cannot be effectively taken
[0003] It can be seen that the above-mentioned existing oil-gas-water flow measurement system obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.

Embodiment Construction

[0027] In order to further explain the technical means and effects adopted by the present invention to achieve the intended purpose of the invention, the specific implementation methods, Structure, characteristic and effect thereof are as follows in detail.

[0028] Please refer to FIG. 1 , which is a schematic flow diagram of an embodiment of the oil-gas-water three-phase on-line non-separated flow measurement system of the present invention. The oil-gas-water three-phase online non-separated flow measurement system is used to measure the flow of oil, gas and water in a single well, which includes: a three-phase non-separated flowmeter 100 , an on-site secondary instrument 300 and an industrial computer 400 . The inlet of the three-phase non-separated flowmeter 100 is connected to a single well oil-gas-water mixture pipeline for real-time measurement of the flow of oil, water and gas in the oil-water-gas mixture. The on-site secondary instrument 300 is connected to the above...

Abstract

The invention relates to an integrated oil-gas-water three-phase online flow measurement system which comprises an integrated three-phase flow meter, a site secondary instrument and an industrial control computer. The three-phase integrated flow meter includes a main pipe, a venturi device which is arranged on the main pipe and used for measuring the flow of the fluids in the main pipe, a conductivity measuring sensor which is arranged in the main pipe and used for calculating the gas phase fraction of the small gas bubble, the gas phase fractions of oil, gas and water, and the flow rate of the gas and liquid, a capacitance measuring sensor which is arranged in the main pipe and used for calculating the gas phase fractions of the big and small bubbles, the gas phase fractions of oil, gas and water, and the flow rate of gas and liquid and a Gamma densimeter which is arranged in the main pipe and used for calculating the density of the fluids. The integrated oil-gas-water three-phase online flow measurement system has the advantages of accurately measuring the water content of the condensate oil of the high-pressure condensate gas well, realizing the online monitoring of the oil gas well and becoming more practical.

Description

technical field [0001] The invention relates to a flow measurement system in the field of oil and gas exploitation, in particular to an oil, gas and water three-phase on-line non-separated flow measurement system. Background technique [0002] At present, during the development of high-pressure condensate gas fields, there has always been the problem that the water content in condensate oil cannot be accurately measured. Condensate gas centralized processing stations usually use gas-liquid separators, flow meters and analytical tests to measure oil, gas and water. Tarim high-pressure condensate gas well has a large gas-oil ratio (2000m 3 / t above), large oil-water density difference (nearly 0.4t / m 3 ) and other characteristics, it is difficult to obtain representative oil-water mixed samples in the existing technological process, and it is impossible to grasp the water content and change trend of a single well, and it is impossible to correctly analyze the dynamic analysis...
