STUDY OF THE WEST-EAST TREND NATURAL GAS ACCUMULATION ZONE IN THE MIDDLE OF THE ORDOS BASIN, CHINA

摘要: 鄂尔多斯盆地已发现的工业气田刘家庄、胜利井、长庆、镇川堡、吴堡等皆分布于中部东西向构造带上,而盆地其它地区仅个别井有气显示或产少量的工业气流。它们的储层为奥陶系碳酸盐岩或石炭、二叠系煤系地层中的砂岩和薄层灰岩,气源均与奥陶系或石炭、二叠系烃源岩有关,都为纯气藏,显示出良好的一致性。这种工业气田带状分布于盆地中部东西一线不是偶然的,反映着中部过渡构造带对它们成藏及分布的控制作用。以中部构造带为背景将它们从相同或相似的成因背景上联系起来归入中部东西向天然气聚集区。显然,该区是天然气勘探的最有利目标。Abstract: The discovered industrial gas fields, like Liujiazhuang, Shenglijing, Changqing, Zhenchuanbu and Wubu in the Oudos Basin are all located in the west-east trend tectonic belt of the Middle. There are gas showings or a small amount of gas flows in only rare wells in the other regions of the basin. Their reservoirs are the Ordovician carbonate rock or sandstone and thin-bedded limestone in the Carboniferous and the Permian coal measures strata. The gas sources are pure gas pools and are all related to the Ordovician or the Carboniferous and the Permian hydrocarbon source rocks. They show good identity. Industrial gas fields zonally distributed in west-east trend in the middle of the basin is not accidental. It reflects the controlling action of the middle tectonic belt to the pool-formation and distribution of these fields. Taking the middle tectonic belt as setting and linking their same or similar genetic background together, theas fields can be included into the west-east trend natural gas accumulation zone of the Middle. Obviously, this zone is the most favorable target for natural gas exploration.
