摘要：
Low energy sedimentary environment with weak water power and high salinity of formation water are the main requirements of low-resistance oil layer development. Whereas part of formation penetrated by hydrocarbon migration, which shows larger bend degrees of conductive tunnels in formation and higher resistivity measurement due to the oxidization of the residual crude oil, forms high-resistance water layer. Because of the complexity of accumulation conditions, these two difficult reservoirs exist in Putaohua reservoir of Weixing oilfield widely. Combined with these accumulation regularities, this paper analyzes and summarizes the complex oil and water distribution characteristics, provide recognition means, so as to enhance the logging evaluation precision of these two difficult reservoirs effectively.
