储层敏感性流动实验评价方法在储层保护中的作用研究

Study on the Role of Reservoir Sensitivity Flow Experimental Evaluation Method in Reservoir Protection

在油田勘探、开发的整个过程中,都会有不同流体进入储层,这些流体与储层发生物理、化学作用,造成储层伤害,导致油田产量降低。储层敏感性研究是实现储层保护,减小储层伤害的必要手段。本次通过实验手段,在M断块开展储层敏感性研究,确定研究区为无速敏、弱水敏、弱碱敏、中等偏弱酸敏储层,指导今后在区内开展钻井、注水及储层改造措施时储层保护工作。

During the whole process of oilfield exploration and development,different fluids will enter the reservoir.These fluids have physical and chemical effects with the reservoir,causing reservoir damage and reducing oilfield production.Reservoir sensitivity study is a necessary means to achieve reservoir protection and reduce reservoir damage.This time,through experimental means,the reservoir sensitivity study is carried out in the M fault block,and the study area is determined to be non-speed sensitive,weak water sensitive,weak alkali sensitive and moderately weak acid sensitive reservoirs,which will guide the reservoir protection work in the future when drilling,water injection and reservoir reconstruction measures are carried out in the area.
