摘要
大牛地气田为致密砂岩气藏,D井区经过8年多的规模开发已处于开发中后期阶段,气井自然稳产期结束,受管网压力制约,气藏产量迅速递减,稳产困难。为延长稳产期,在气藏增压集输地面工艺研究的基础上,采用数值模拟方法进行增压开采方案优化模拟,研究表明D井区整体增压开采可以维持气藏稳产,较自然开采可多采天然气5.11×108m3,气藏采出程度提高4.11%。
Daniudi gas field is a tight sand gas reservoir, and D district has been in mid - late stage more than 8 years scale exploit, after ending the natural stable period of gas well. Constrained by the pipe network pressure, the production of the gas reservoir has declined rapidly and it is difficult to maintain its production steadily. In order to prolong the stabilization period, based on the pressure boosting research, the paper simulates the pressure boosting solution with numerical simulation. The result of simulation shows pressure boosting can maintain stable production in gas reservoir of D district. Compared with natural exploit, production of the gas reservoir will increase 5.11 × 10^8m^3 and recoverable reserve increase 4.11% after pressure boosting.
