利用水平井技术开采底水油藏能够提高油藏的最终采收率,但同时又出现了底水脊进现象,目前还没有好的解决办法。在水平井下衬管、盲管和管外封隔器(ECP)组合的管柱完井时,对水平井完井进行分段优化来调整水平井的流人剖面,从而可以有效避免跟端附近出现的端部效应,减缓可能出现的底水脊进。在出水的情况下,通过压力检测,发现出水层位,实施有效的堵水措施。在带管外封隔器ECP及衬管(包括打孔管)完井方法下,分别建立油藏流动模型和井筒流动模型.对油藏流动和井简流动进行耦合.得出产能预测模型。

Horizontal well is used to enhance the oil recovery in the bottom water reservoir; however, the phenomenon of bottom cresting appears afterward, there is not good solution at present. With the combination of liner, blank pipe and ECP, the selective completion of horizontal well can be optimized to adjust the horizontal well inflow profile, which can effectively avoid the end effect near the heel, and this can delay bottom water cresting. In the case of water breakthrough, water producing location can be found through pressure testing, and effective water block can be performed. Based on the selective completion, this paper establishes the reservoir model and the pipe flow model and the coupling model, so the productivity forecasting model under this completion method is gained.
