摘要
通过对岩石导电机理的研究,即岩电参数实验和水驱岩电实验,描述了水淹前后储层的岩性、物性及电性变化特征,提出电阻率相对值法识别水淹层方法。通过现场应用,解释符合率提高了5.5个百分点。
This paper studies rock conductive mechanism through litho-electric experiment and waterflood litho-electric experiment,describes the lithology,petrophysical property and electric property of reservoir before and after watered-out,and proposes to identify watered-out zone by relative resistivity.Field application shows that the coincidence rate of interpretation has improved 5.5%.
