AI Technical Summary
In the existing technology, the quantitative measurement of gas production in pumping wells has not been effectively solved, resulting in a lag in the dynamic tracking of oil well production, high labor intensity, long measurement cycle, and difficulty in timely adjustment.
Based on the dynamometer card and the gas state equation, a gas production model for pumping well dynamometer cards is established. By obtaining the wellhead fluid production and gas production models, the gas production corresponding to each pumping dynamometer card is calculated and accumulated. The gas height is solved by combining the gas state equation and the nonlinear residual equation to accurately calculate the gas production.
It enables quantitative measurement of gas production from pumping wells, reduces labor intensity, improves production efficiency, and allows for real-time tracking of well production dynamics and dynamic analysis of gas production variation patterns.
