摘要:

四川盆地仪陇￣平昌地区是侏罗系大安寨段页岩油的有利勘探开发区，为明确研究区内页岩油的相对富集区，文中结合地质异常理论，采用主成分分析方法，选取页岩有效厚度、镜质组反射率、总有机碳质量分数、地层压力系数、脆性指数等5项地质参数为评价指标，对数据集合采用标准化处理、主成分分析降维和确定权重等技术手段，建立了页岩油综合评价的无因次线性组合，提出了一种针对研究区大安寨段页岩油有利区域分布的评价方法。评价结果表明：研究区内页岩油一类有利区域分布在龙岗气田的Lg9—Lg28井地区、仪陇￣南部县城附近和税家槽附近的Lg42—Lg30井地区；二类有利区域位于平昌、营山县城附近等地区。采用主成分分析方法确定的综合评价模型可以有效地指导新井部署和老井复查。

Abstract:

Yilong-Pingchang area in Sichuan Basin is a favorable exploration and development area for shale oil in Jurassic Daanzhai member. In order to clarify the relative enrichment area of shale oil in the study area, the principal component analysis method is used in combination with the geological anomaly theory. Five geological parameters such as effective shale reservoir thickness, vitrinite reflectance, total organic carbon content, formation pressure factor and rock brittleness index are selected as evaluation indicators. Technical means such as standardized processing, principal component analysis for dimension reduction and weight determination are adopted for the data set. A dimensionless linear combination of the shale oil comprehensive evaluation is established, and an evaluation method for shale oil distribution in favorable areas of Daanzhai member in the study area is proposed. The result shows that the first class favorable areas of shale oil are distributed in the well Lg9—Lg28 area of the Longgang gas field, the area around Yilong-Nanbu County and the well Lg42—Lg30 area near Shuijiacao. The secondary favorable areas are located in the area around Pingchang and Yingshan County. The comprehensive evaluation model determined by the principal component analysis method can effectively guide the deployment of new wells and the review of existing wells.
