孤岛油区浅层气藏开采规律浅析

An approach to recovery law of Shallow gas reservoir in Gudao oil province

孤岛油区气藏是胜利油田开发较早的气藏之一 ,也是目前胜利油区最大的浅层气藏 ,目前已进入开发后期。随着采出程度的提高 ,出现了地层压力逐年下降 ,停产井增多 ,气井出砂出水严重 ,低产能井增多等诸多问题。通过进行气藏精细描述研究 ,分析各类含气砂体的开采规律 ,明确该气藏资源动用、采出、封闭、剩余等情况 。

Gudao gas reservoir is one of the earliest and biggest developed shallow gas reservoirs in Shengli oilfield, Now it had entered later developing period. As the ratio of total gas produced to OGIP increases, formation pressure decreases year by year, the number of shut down wells increases, sand and water producing are getting serious, and the number of low production wells increases. Through accurate gas reservoir description, the recovery law of various gas sands has been analyzed, and the state of producing, recovering, sealing and remaining of gas reserves has been made clear to improve the development of the reservoir.
