Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Gamma or X-ray multiphase flow and composition measurements are currently used at home and abroad, which are based on the principle of emitting one or more waves to determine the component fractions of the individual sub-streams constituting the mixed fluid. However, these flow meters are radioactive and therefore unsafe to deploy in the oil field, causing harm to the health of the operators, while their accuracy is greatly reduced by the presence of gas (e.g., over 90% gas, with an error of over 20%). Other non-radioactive commercially available meters rely on the electrical properties of the mixed fluid using capacitance and conductance readings to determine oil, gas, and water composition. In addition, they use pressure sensors, temperature sensors and interrelationships for liquid flow measurement. These multiphase flow meters have safety advantages, however, their accuracy is poor in the 40% -60% water cut range. The reason is that in this range the mixed fluid is neither fully conductive nor insulating, resulting in almost the same output of the sensor in this range. Furthermore, these meters are inaccurate in the range of water content greater than 90%. Therefore, flow measurement of multiphase flows still requires extensive research and development work, particularly in improving the accuracy of full-flow multiphase flow conditions.
The utility model provides a based on ultrasonic method analysis profit composition measuring device to improve the technical purpose of the degree of accuracy of the multiphase fluid condition of full flow.
