| 摘 要： | 与直井相比,水平井开发具有缩短油井井距,扩大泄油面积,提高临界锥流量,更好地控制注入流体、改善波及效率等优势。在相同采液量的情况下,水平井可以降低采液强度,减缓含水上升速度。特高含水期河流相储集层的顶部是剩余油富集区,利用水平井技术挖掘正韵律厚油层顶部剩余油,取得了很好的开发效果,最终采收率较直井开发提高了14个百分点。

| Abstract: | Compared with vertical wells, horizontal wells has the advantages of shortening distance between wells, extending well drainage area, increasing critical coning flux, controlling the injection fluid and improving oil displacement efficiency. When fluid offtake is the same, horizontal wells can reduce intensity of produced fluid and increase water cut rate. There is abundant remaining oil in the top of reservoir of fluvial facies, it was exploited using the technique of horizontal well, and ultimate water displacement recovery increased by 14% compared with vertical wells. |
