高含水期水平井挖潜物理模拟
Physical simulation for horizontal well tapping remaining oil at high water cut stage
摘要
Abstract
Considering the coupling of flow in reservoir and horizontal well, a large scale artificial consolidated multi-layer model reflecting the normal rhythm is established according to the water flooding scale criteria, and the reliability of the model is proved in terms of characteristics of pore structure and oil water seepage flow. Through the physical model, differences between effects of potential tapping with different methods and mechanisms of improving recovery using horizontal well compared to vertical are studied. The result shows that under the staggered well pattern and reservoir with positive rhythm, remaining oil at high water cut stage always exists in the central area of the well grope and the top of the reservoir; the effect of using horizontal well tapping at high water cut stage is better than vertical under different production indexes. Besides, the control ability of horizontal well over remaining oil in lower part of reservoir and corner area of well grope is also stronger; allocation relation between horizontal well and conventional well pattern can exert an effect on potential tapping, and with the increase of water cut, production performance of horizontal well would show different features.关键词
