大王北油田沙二段储层岩性较复杂,非均质性强,单层厚度较薄,底水较活跃,导致油层与围岩、油层与水层电阻率差异小,储层岩性识别及油气水层解释面临较大困难。基于岩心、岩屑与常规测井资料对比分析,总结了该储层各类岩性的测井响应特征;应用薄层测井评价技术、建立适用的解释模式等方法,能准确的判别油气水层,提高大王北油田沙二段储层含油性解释精度。
Reservoir of Sha2 Member of Dawangbei Oilfield has relatively complex lithology, strong heterogeneity, thin single layer thickness and active bottom water, resulting in small difference in resistivity between reservoir and reservoir, reservoir lithology identification And the interpretation of oil, gas and water layers are facing greater difficulties. Based on the contrast analysis of cores, cuttings and conventional logging data, the logging response characteristics of various lithologies of this reservoir are summarized. By applying thin-layer logging evaluation technology and establishing applicable interpretation modes, it can accurately distinguish oil and gas Layer, to improve the interpretation of oil-bearing interpretation of reservoir Sha 2 in Wangbei Oilfield.
