东濮凹陷气田深层气藏采气工艺技术研究

RESEARCH ON GAS PRODUCTION TECHNOLOGY IN DEEP SEATED GAS RESERVOIR

针对深层气藏降压开采产生反凝析的问题,从射孔、压裂、排液等方面进行了研究,优化气田的采气工艺设计,寻找出适合深层气藏的采气工艺。小油管排液采气、泡排、撬装式制氮气举等排液采气工艺应用于东濮凹陷的白庙、户部寨等深层气藏,改善了井底状况,降低凝析油的损失,气井实施取得了较好的效果。

Because of blowdown,retrograde condensation will occurred in deep seated gas reservoir.This will result in condensate loss,and also increase development difficulty.Therefore ,further optimization gas production technology design will radically raise development level of condensate gas reservoir.On the basis of research on the perforating,fracturing and flowing back etc.,this paper proposes a set of gas production technology suitable for deep seated gas reservoir.The gas production technology,including narrow tube flowing back,foam flowing back and gas lift etc.,is applied in Dongpu hollow's Baimiao and Hubuzai etc.deep seated gas reservoir,it improve down-hole condition and reduce the condensate loss.
