摘要
H油田长8岩性油藏位于鄂尔多斯盆地西南缘,储层致密,天然裂缝发育,采用水平井开发产量递减快,急需开展裂缝性致密油藏注水提高采收率探索。
There was two characteristics of tight reservoir and fracture development in Triassic Chang 8 tight sandstone reservoirs,H oilfield.With the exploitation by horizontal wells,the production of oil wells was decreasing rapidly,which resulting in a very low recovery.There is an urgent need to explore water injection in fractured tight reservoirs to improve oil recovery.
