天池构造位于鄂尔多斯盆地西部天环向斜西翼,为一短轴穹窿构造。该构造于1954年发现,1985年经地震复测证实。二叠系下统山西组低界T_9反射层的构造轴向为北北东,长轴9.4km,短轴7.5km,闭合度200m,圈闭面积53.5km～2,高点埋深3846m,南翼被一条北东东向逆断层切割,断距90m。无断层影响的构造圈闭面积为26km～2,闭合度150m。 1981年钻天深1井过程中,曾往奥陶系风化壳石灰岩中放空、漏失,气测甲烷为0.024～0.1％,岩心裂缝发育。下古生界碳酸盐岩地层中共有17个缝、洞发育段,累厚183.4m。该井未进行中途测试。 1986年1月5日以奥陶系为目的层钻天1井,
The Tianchi structure is located in the west wing of the Tianhuan syncline in the western Ordos Basin and is a short axis dome. This structure was discovered in 1954 and confirmed by an earthquake re-test in 1985. The lower member of the Permian Shanxi Formation low-level T_9 reflector is north-north east with a long axis of 9.4km, a minor axis of 7.5km, a closure of 200m, a trapped area of 53.5km ~ 2, a high buried depth of 3846m and a south The wing is cut by a northeast-east thrust fault with a 90-meter break. The fault-free structural trap area is 26km ~ 2 and the closure degree is 150m. During the drilling of Well ZST-1 in 1981, the limestone in Ordovician weathering crust was drained and lost. The gas methane content was 0.024-0.1% and core fractures developed. In the Lower Paleozoic carbonate strata, there are 17 seams and cave developmental sections with an accumulated thickness of 183.4m. The well did not undergo a mid-range test. January 5, 1986 Ordovician for the purpose of drilling layer 1 well,
