摘　　要：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。The studied area Shizhuang, Mengzhou city, Henan province, is located at the southeastern margin of the Jiyuan Basin. Stratigraphieally, the area belongs to the Taihangshan region of Shanxi subdomain of North China domain. The main strata outcropped in the area include Mesozoic Triassic, Cenozoic Tertiary and Quaternary. During the Mesozoic the area experienced a long-term period of terrestrial basin facies deposition, and a large amount of organic matter was concentrated in the rocks. Consequently, the Mesozoic strata are always regarded as coal-series strata and target for the prospecting of coal resources. However, the analysis and research of dark-grey rock series sampled from the Upper Triassic Tanzhuang Formation show that the Tanzhuang Formation in the area is a series of strata containing oil source rocks, and that the area is an oil reservoir on the eastern side of the Jiyuan Basin where some oil-gas resources with a fair scale may be formed under certain geological conditions causing the oil-gas to be transported, trapped, covered and preserved. The result obtained in the research provides some revelation for the prospecting of oil-gas resources in the Jiyuan Basin in northwest Henan province.
