Geological Characteristics of Difficult Reservoirs in Logging Interpretation

Abstract: Logging measurement is the comprehensive reflection of solid particles and liquids in formation. 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. Using geological characteristic parameters, such as, the distance of wells and scale faults, the formation structural location, resistivity measurement, sedimentary microfacies,thickness and porosity conditions, to evaluate oil and water property of the two difficult reservoirs, good results have been obtained.
