摘要 鄂尔多斯盆地的天然气勘探发展对全国天然气市场供应具有重要意义。目前该盆地探明率低,还有较大勘探潜力,其天然气储量增长将主要集中在上古生界山2段和下古生界马五段,下古生界以岩溶储层为主,建议主攻目标为靖边潜台东部及周边,2个预备地区为中央古隆起东坡和宜川—黄龙。上古生界以大面积地层岩性油气藏为主,主攻目标为统万城—镇北台—子洲—清涧和府谷—佳县地区,3个预备地区为铁克苏庙及靖边潜台西南侧的城川地区、西南(镇原)和宜川—黄龙地区。文章最后针对该盆地目前的勘探进展情况,提出了一系列的建议。 Gas exploration in the Ordos Basin is very important to gas supply in the whole country. Current gas exploration maturity is relatively low and large gas exploration potentials still exist in this basin. Study reveals that growth of gas reserves will concentrate in the second member of Shanxi Formation of Upper Paleozoic and the fifth member of Majagou Formation of Lower Paleozoic. The Lower Paleozoic is dominated by karstic reservoirs and their exploration should be focused on the eastern part of Jingbian buried platform and its periphery, followed by the eastern slope of the central paleohigh and Yichuan-Huanglong areas. While the Upper Paleozoic is dominated by extensive stratigraphic and lithological reservoirs and their exploration should be focused on Tongwancheng-Zhenbeitai-Zhizhou-Qingjian and Fugu-Jiaxian areas, followed by Tiekesumiao and Chengchuan areas in the southwest of Jingbian buried platform, southwestern Ordos Basin (Zhenyuan area) and Yichuan-Huanglong areas. Some proposals are presented for gas exploration.
