drainage volume

Reservoir engineering method is adopted to calculate recovery indexes such as the horizontal well's limited recovery factors, well drainage area, reservoir limited recoverable reserves and water cut an.

应用油藏工程方法计算了水平井极限采收率、泄油面积和油藏极限可采储量、含水率等开发指标,其结果与数值模拟结果基本吻合。

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.

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。
