《鄂尔多斯盆地东部上古生界煤成气形成条件及远景评价》课题研究任务,系国家“六、五”期间重点科技攻关项目之一,由陕西地矿局第八地质队和山西地矿局二一五队共同承担。他们自1982年编制设计,于1985年9月完成了报告送审稿。地矿部委托陕西、山西两省地矿局对送审稿组织了初审。报告经补充修改后,于同年12月30日由地矿部终审通过。课题研究报告认为,鄂尔多斯盆地东部约12万 km~2 范围内,在石炭—二叠纪时,经历了由海进的滨海沉积至海退的陆源碎屑沉积的演变过程,具有形成煤成气的沉积环境。本区气
“Ordos Basin in the Upper Paleozoic coal-formed gas formation conditions and long-term evaluation of” research task, the national “six or five” key scientific and technological projects during the one by the Shaanxi Bureau of Geology and Mineral Resources eight geological team and Shanxi Bureau of Geology and Mineral Resources A team of 15 shared. They were designed in 1982 and completed their report for review in September 1985. The Ministry of Geology and Minerals commissioned the Bureau of Geology and Mineral Resources of Shanxi Province and Shanxi Province to organize the preliminary examination of the draft for review. After the report was revised and supplemented, it was finally passed by the Ministry of Geology and Minerals on December 30 of the same year. According to the research report, the evolution process of terrigenous clastic sediments from seaward to seabed sedimentation to sea retreat during the period of Carboniferous-Permian about 120,000 km ~ 2 in the eastern part of the Ordos Basin shows that the formation of coal-derived gas Sedimentary environment. This area gas
