塔里木盆地沙参2井海相油气首次发现的历程与启迪

沙参2井是中国古生代海相层系油气首次获得重大突破的标志.从1970年战略评价塔里木盆地,到1984年塔里木盆地北部沙参2井在奥陶纪白云岩中获高产油气流,再到1990年塔河奥陶系大油田的发现,塔里木盆地30年的勘探开发实践带来了许多启迪,也形成了一系列中国海相油气成藏理论和超深层海相碳酸盐岩缝洞型油田勘探开发技术.回顾沙参2井的发现历程,对于在未来的油气勘探开发中解放思想、勇于创新具有重要的借鉴意义.

The first marine petroleum discovery in China and its significance

The Well Shacan-2 in northern Tarim Basin was the first marine petroleum discovery in China, indicating a strategic breakthrough in the oil and gas exploration of marine sequences in the country. The exploration histroty of the Tarim Basin can be traced back to the 1970s when a strategic project was launced to assess the petorluem potential of the basin. In 1984, the Shacan-2 was tested with a high rate of oil flow in the Ordovician dolomite in northern Basin. In 1990, the giant Ordovician oil field was discovered in Tahe area. More than 30 years of exploration practice had not only inspired us grealty but also produced technology series for developing oil and gas from fractured-vuggy reservoirs in marine carbonates. A review of the history may serve to help us to be more brave and innovative in our future path of finding oil and gas for the country.
