摘　　要：针对注入水沿水平井压裂缝窜进,见水后产量下降、开发效果变差等问题,提出了低渗透油藏直井多井间隔注水、多级压裂水平井分段间隔采油开发方式,提出了间隔注水、分段间隔采油工作制度设计方法,以实际区块为例,设计了注采参数,并预测了10年生产指标,提出了具体实施方法。Aiming at the problems of rapid water breakthrough along the fractures of horizontal well, severe production decline and poor development effect in low-permeability reservoirs, we propose the development method of multiple vertical wells intermittent water injection and separated horizontal well production.Then,the working system design method is presented. Finally, taking an actual block as an example, we design the injection-production system.The production index for 10 years is predicted,and the specific implementation methods are proposed.
