【摘要】：对青海鱼卡地区侏罗系油页岩特征及以往研究成果分析的基础上,结合油页岩参数井的测井、录井及测试数据,得到研究区油页岩具有高电阻率、高声波时差、低密度及低自然伽马的测井响应特征。根据参数井数据建立3种含油率预测方法并对比其预测效果,最终选择效果好、应用方便的多元回归分析方法定量判别含油率。通过研究区单井油页岩识别,综合考虑油页岩的埋深、厚度、含油率及构造影响等因素,初步建立了油页岩目标区的优选标准,根据标准在研究区划分出3个A类和2个B类目标区;对A类目标区油页岩资源进行计算,共计3.41×109 t。
[Abstract]:Based on the analysis of Jurassic oil shale characteristics and previous research results in Yuka area, Qinghai Province, combined with logging, logging and test data of oil shale parameter wells, the oil shale in the study area has high resistivity and high acoustic time difference.Logging response characteristics of low density and low Natural Gamma.According to the data of parameter wells, three kinds of oil content prediction methods are established and compared with their prediction results. The result is good, and the multiple regression analysis method is used to quantitatively judge the oil content rate.Through single well oil shale recognition in the study area and considering comprehensively the factors such as the depth, thickness, oil content and structural influence of the oil shale, the optimal selection standard of the oil shale target area is preliminarily established.According to the standard, there are 3 A and 2 B target areas in the study area, and a total of 3.41 脳 10 ~ 9 t oil shale resources in A type target area are calculated.
