注水井分层水咀调配思路

The Distribution Ideas of Injection Well Layered Faucets

分层注水是油田缓解层间矛盾、提高油田采收率的一个重要措施。中原油田采油三厂多数井下分注井的层段性质分布不均,主要是层间差异突出,同一层内还受层内矛盾、平面矛盾影响,注好水、注够水很难掌握,故注水井的分层水咀选择对水井能否有效注水、保持地层压力尤显重要。文章通过对强吸水层及弱吸水层的稳定特性分析,找出了如何在同一注水压力下,高效可靠选择分层水咀以达到地质要求的调配方法。

The layered water injection is an important measure to ease the contradiction between layers and improve oil recovery for oilfield.The Zhongyuan Oilfield three factory most underground injection well layer properties are unevenly distributed,mainly interlayer contradiction.It is primarily highlight differences between the layers,Layer properties within the same layer is also affected by the layer and plane contradictions.Water injection well and enough is difficult to master.Therefore,the selection of Water injection well Stratification of water nozzle is of utmost importance to the effectiveness of water injection and to maintain reservoir pressure.The article through to the stability characteristics analysis of the strong absorbent layer and the weak absorbent layer,found out reliable and efficient deployment method to select Stratification of water nozzle faucets to achieve geological requirements.
