Abstract—Pressure is a essential factor to be determined in gas field development. How to obtain the accurate current formation pressure is a difficulty encountered in developing low permeability gas reservoirs like Jingbian Gasfield. For this kind of low permeability gas reservoir, in the premise of finishing the production task, to do the least work to meet the need of the development of research is a necessary solved problem in the gas reservoir development. In allusion to these problems, the pinpoint formation pressure test method is adopted to calculate the current formation pressure of single well in this file. Conclusions obtained:1)The calculating gas well current formation pressure method is a feasible way to solve those problems.2)Using the static pressure test data to calculate gas well current formation pressure is suitable for Jingbian Gasfield, according to the comparison in this essay. 3)The error analysis has been done by using the static pressure data and long-term (shut-in time is more than 80 days) shut-in data, which can also be used to calculate formation pressure. The reasonable range of error control of three kinds of well can be obtained by deducing. By judging the range, we can determine whether the obtained calculating formation pressure test result is correct or not.
