Abstract: 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.
