摘要:
针对姬塬地区上三叠统长2油层组物源方向及砂体展布方向不明的问题,根据区域地质背景和沉积特征,综合利用重矿物组合和砂岩轻矿物,砂地比等厚线等方法对长2油层组物源进行分析。结果表明:姬塬地区长2油层组属曲流河三角洲相中三角洲平原亚相沉积,岩石类型包括砂岩、粉砂岩、泥岩及其过渡类型,其中以泥岩和细砂岩为主,重矿物主要为锆石、金红石、电气石、白钛矿和榍石等,主要物源来自研究区的NE方向。对长2油层组的砂体展布方向分析和储层预测具有参考意义。
Abstract:
Aiming at the unidentified problem of the provenance direction and the direction of sand body exhibition cloth of the Upper Triassic Chang 2 pay set in Jiyuan region, according to the regional geological background and sedimentary characteristics of the region, the provenance of Chang 2 pay set is analyzed using comprehensive analysis methods of heavy minerals assemblages, light minerals of sandstone, such as sand than in thick lines, facies analysis. The results have disclosed that Chang 2 pay set in Jiyuan region is delta plain subfacies of meandering delta facies; rock types include sandstone,siltstone, shale and its transition type, in which fine sandstone and mudstone are main; the main provenance of the area originates from NE orient. These research results have vital significance for sandstone distribution analysis and reservoir prediction of Chang 2 pay set.
