摘要(Abstract):
由于储层层内、层间及平面不均衡性,经过长期注水开发,导致注入水沿高渗透条带循环,很难进一步扩大波及体积,使得吨油注水量大幅度增加。为改善注水开发效果,以“动态普查,静态确认,测试验证”为指导思想总结形成了低效循环条带分析判别方法:一是运用四参数决策系数法找出低效循环条带可疑井组;二是结合砂体沉积特征确认低效循环条带存在层位、方向;三是运用测试资料进行验证。运用该方法对典型区块进行了普查治理,已初见成效。
Because of inner-layer,interlayer and areal heterogeneity of reservoir,after a long period of water flooding,injected water circulates in high permeability channel,sweep volume cannot be enlarged,and injected water volume of per ton increases a lot.This paper summarizes identification method for low effective circulation channel: first,using four parameters decision factors method to find out low effective circulation channel's suspicious well group;second,determining the horizon and direction of low effective circulation channel combining with sand body sedimentation characteristics;third,to verify using test data.Treatment with this method has some effect.
