摘　　要：本文使用DSE动态污染试验装置,对影响地层损害的几个井眼水动力学参数,如压力差、滤失时间、泥浆温度、环空泥浆上返速度和钻具转速等进行了实验分析,并进行了动态和静态污染对比试验,其试验结果对于损害机理分析、动态污染室内评定标准的制定以及生产实践都具有重要意义。In this paper, the DSE dynamic simulation equipment is used to study the effect of such parameters as pressure difference, time, temperature, mud flow rate and rotational speed of drilling tool on the formation damage. Then, the comparative analysis between dynamic state damage and static state damage is completed. The experiment results play an important role in the analysis of formation damage mechanism, in the determination of damage evaluation standards, and in production practice.
