地质矿产部华东石油地质局在苏北泰兴县黄桥地区打的苏泰174井,1983年3月,在一次中途测试中,首次获得具工业价值的二氧化碳气流,日产二十多万立方米。苏泰174井位于东台坳陷黄桥斜坡带西断块,首次测试目的层是二叠系栖霞组石炭岩,气层深度1800多米,气体含二氧化碳98.67%,氮1.33%。同年6月,该井钻穿二叠系栖霞组、石炭系、泥盆系,进人志留系。后进行第二次地层测试,测试 East China Bureau of Geology and Mineral Resources East China Petroleum Geology Bureau Taishan County, Taibei, Huangqiao hit the Su Tai 174 wells in March 1983, in a midway test, for the first time with industrial value of carbon dioxide gas flow, Nissan more than 200,000 cubic meters. Well Suotai 174 is located in the west fault block of Huangqiao slope in Dongtai Depression. The first test target layer is Permian Qixia Formation carbonaceous rock with depth of more than 1800 meters. The gas contains 98.67% of carbon dioxide and 1.33% of nitrogen. In June of the same year, the well drilled through the Permian Qixia Formation, Carboniferous and Devonian systems and entered the Silurian system. After the second formation test, test
