Analysis of Watercut Variation Law of Horizontal Wells of L Oilfield in Bohai Sea
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.
