再论塔里木盆地古生代油气勘探潜力——纪念沙参2井油气重大突破20周年

1984年塔里木盆地北部沙参2井在古生界海相碳酸盐岩中钻获高产油气流,开创了塔里木盆地古生代油气勘探的新局面。经过20年的不懈努力,在古生界发现了塔河大油田、和田河大气田等18个油气田,表明了塔里木盆地古生界油气资源丰富,成藏条件优越,具有形成大型-特大型油气田的地质条件,其勘探潜力巨大。

Re-discussion on exploration potential of Paleozoic in Tarim basin:20th anniversary of significant discovery in Shacan 2 well

In 1984,a high-rate oil flow has been tested from the Paleozoic marine carbonates in Shacan 2 well,northern Tarim basin, which means a new prospect has been opened up in the Paleozoic petroleum exploration in the basin.Through a 20-year sustained efforts,18 fields,including the large Tahe oilfield and Hetianhe gasfield,have been discovered in the Paleozoic.It shows that the Paleozoic in Tarim basin has abundant oil and gas resources,favorable reservoiring conditions,and suitable geologic conditions for the formation of large-giant oil and gas fields,thus its exploration potential is very large.
