河南省孟州市石庄位于济源盆地东南缘,地层属华北地层区山西分区太行山小区。出露的主要地层有中生界三叠系、新生界第三系、第四系。中生代经历了长期陆相湖盆沉积阶段,岩石中有机物含量高。所以该区中生界地层一直作为煤系地层并进行了煤矿资源的勘查工作。本文通过对中生界上三叠统谭庄组的灰黑色岩系取样分析研究,认为该区上三叠统谭庄组为一套含生油岩地层,是济源盆地东侧生油区。在具备一定的运移、储集及盖层等地质条件下可以形成一定规模的油气资源。为今后在河南西北济源盆地寻找油气资源提供了启示。
Shizhuang, Mengzhou City, Henan Province, is located in the southeast margin of Jiyuan Basin. The stratum belongs to the Taihang Mountain community in Shanxi Sub-region of North China. The main strata exposed are Mesozoic Triassic, Cenozoic Tertiary, Quaternary. The Mesozoic experienced a long-term continental lacustrine sedimentary stage with high organic matter content in the rock. Therefore, the Mesozoic strata in this area have been used as coal strata and coal resources exploration work. Based on the sampling analysis of the gray-black rock series of the Triassic Tanzhuang Formation in the Mesozoic, this paper considers that the Upper Triassic Tanzhuang Formation is a set of oil-bearing rock formations and is the oil producing area on the east side of the Jiyuan Basin. With certain migration, reservoir and cap rocks and other geological conditions can form a certain scale of oil and gas resources. It will provide enlightenment for searching for oil and gas resources in Jiyuan Basin of northwestern Henan Province in the future.
