摘要
针对长岭坳陷地区地质特征,进行页岩油勘探潜力分析。以泥页岩油气评价单元为基础模型,初步判断该泥页岩区域是否具有生成大范围页岩油藏的能力;结合地质实测数据资料,建立有机地球化学参数模型,系统地评价该区泥页岩的生油能力;进行储量计算时,对关键参数的补偿系数进行校正,使页岩油储量的预算值更接近实际。利用该套综合评价标准,对长岭地区嫩江组一段进行页岩油评价预测,划分出研究区东侧和黑帝庙次凹东北部为有利区,其余地区为远景区,不存在目标区。
Exploration potential of shale oil is analyzed based on the geologic features of the Changling depression.Taking the unit for evaluation of mudstone/shale oil and gas as the basic model,the potential of extensive shale oil reservoir occurrence in the mudstone/shale area is preliminarily determined;in combination with the measured geologic data and information,organic geochemical parameters are modeled and the potential of oil genesis in the mudstone/shale is evaluated systematically;and the compensation coefficients of key parameters are corrected when reserve is calculated,making the estimated reserve value of shale oil quite well approaching to the reality.By use of this set of criterion for comprehensive evaluation,the Nunjiang Formation member I shale oil in the Changling area is evaluated and predicted,the eastern margin of the study area as well as the southern Yaoyingtai is regarded as the favorable areas and the other areas are just the prospective ones beyond the targets.
