AI Technical Summary
Existing technologies cannot accurately obtain the original formation pressure of developed gas reservoirs, which leads to difficulties in the scientific development of gas reservoirs. Existing methods have problems such as large errors or inapplicability.
By heating and pressurizing the fluid in the developed gas reservoir, the relationship between the fluid pressure and temperature and the water dew point pressure curve are obtained. Combining the relationship between the fluid pressure, temperature and water dew point pressure, the original formation pressure of the developed gas reservoir is calculated.
It enables accurate measurement of the original formation pressure of developed gas reservoirs, provides accurate parameters for the scientific development of gas reservoirs, solves the problem of large measurement errors in existing technologies, and has wide applicability and is fast.
