Abstract

The methods for calculating static pressure at bottom hole in the past do not take the varying temperature, pressure and gas components into consideration. According to the variation range of temperature and pressure, different computation models of gas deviation factor are applied to calibrate the critical parameter of acidic gas with high content of hydrogen sulfide, so as to improve the calculation accuracy of gas deviation factor. And based on the above-mentioned method, the static pressure at bottomhole is calculated. The actual data shows that a relative high accuracy is obtained.

Key words： Feixianguan Formation; third-order sequence; high-frequency sequence; Fuling area
