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。
