THE STUDY ON THE THEORY AND METHOD OF CORE SUSCEPTIBILITY EXPERIMENT TO FLOWRATE

the flowrate susceptibility is an important port of sensitivity experiments of reservoir.This paper points out the such question in cote test for flowrate sensitivity that the experiment results of oil different from that of saltwater for the same core samples,the fluid to saturate the core samples should be single phase to avoid the problems caused by the coexisting fluids,that is the core samples should be saturated by oil if oil is used as testing fluid,and saturated by salt water if salt water as testing fluid,the fromation damage caused by flowrate in production wells is different from that in injection wells,and how to determine the reasonable production and injection flow rate according to the experiment results etc.,and discusses the method to resolve the above-mentioned problems.
