摘　　要：针对吐哈盆地台北凹陷西部雁木西油田储层岩性复杂、地层水矿化度高、第三系因膏岩层发育而采用高矿化度盐水泥浆钻井、有效储层划分难度大等特点,对油田采用的微电极测井识别有效储层的应用效果进行了评价。分析认为:在雁木西油田,微电极测井在井眼条件较好,地层水矿化度变化不大的情况下,可以在高矿化度泥浆条件下较好的识别出有效储层和非有效储层,且对储层中的致密砂岩层、泥岩夹层等识别准确。结合油田油水关系特征,可以准确的识别出有效油、水层,为先期测井解释评价及后期油井投产提供服务。As for the current status of Yan Muxi oilfield in the west of Taibei depression in Tuha basin, that is with complicated reservoir lithology, high reservoir water salinity, drilling with high salinity saline mud in Tertiary because of abundant of gypsolyte layers as well as huge difficulty for effective reservoir zonation, the application effect of micro electric log suggested in the oilfield to identify effective reservoir was evaluated. Through analysis, it was thought that micro electric log can completely well-identified the effective and non-effective reservoir under the circumstance of high salinity mud in good well bore condition and with little changed reservoir water salinity. Moreover, it can accurately identify tight sand and mudstone intercalation in reservoir. With the combination of oil and water relation characteristics, oil and water layer can be accurately identified, which provides service for previous logging evaluation and later oil well production.
