摘　　要：渤海L油田现已进入中高含水期,利用水平井挖潜剩余油,部分水平井初期含水较高或者含水上升较快,影响水平井调整挖潜效果。为改变此现象,对L油田多口水平油井的初期含水和含水上升规律加以总结分析,通过“3类6种”曲线反映其规律变化,并利用数模机理模型进行验证。L oilfield in Bohai Sea has now entered the middle and high watercut period.Horizontal wells are used to tap potential remaining oil,but Some of them have higher watercut or water cut rises quickly in the early stage,which affects the adjustment of potential tapping effect of horizontal wells.In order to change this phenomenon,the law of initial watercut and watercut rise of multiple horizontal oil wells is summarized and analyzed.The change is reflected by the curve of"3 classes and 6 kinds",and verified by the mathematical model.
