| 摘 要： | 详细讨论了辽河双台子油气田气顶砂岩油气藏在开发过程中气窜严重 ,导致大量气顶气过早采出 ,使该油气田中后期开发效果急剧变差的问题 .研究表明 ,该油气田气窜严重的原因 ,一是1 984年 9月以后 ,油井大幅度放大压差生产使气窜加剧 ;二是 1 985年以后频繁补孔使油井避气厚度减少致气窜更趋严重 .此外 ,该油气田加密调整效果不好 ,加密井与老井的井间干扰明显 ,说明油层连通渗流条件较好 ,原有 60 0 m井距已可有效控制储量 ,加密调整似嫌多余

| Abstract: | Shuangtaizi reservoir in Liaohe Oilfield is a typical gas cap sandstone reservoir. Development scheme of gas cap drive was taken in 1980. In the initial stage of development, the effectiveness of oil production is ideal. But in the middle-later stage, the result became rapidly bad. The author analyses the causes of the problem in detail. It is held that it is resulted from increasing production pressure difference from 1984 and increasing wells in pattern many times after 1985. The increases of the pressure difference and the wells in pattern lead to the interconnection and interference among wells. The interconnection and interference make a lof of gas cap gas produced but oil output reduced. |
