塔里木盆地海相古生界油气勘探的进展

The Progress for Onshore Marine Petroleum Exploration of Paleozoic in Tarim Basin.

1984年9月,西北石油局在塔北的沙参2井实现了我国古生代海相油气田首次重大突破后,开创了油气勘探的新领域。特别是“九五”以来,塔河油田的发现和探明,加大了古生界的勘探和研究力度,并取得了重大进展:海相古生界油气取得了新的突破,建立了我国海相古生界成油理论,对奥陶系古岩溶和储集体进行了深入的研究,查明了塔河大油田的基本特征。

In Sept.,1984,Well Shacan No.2was drilled in Tabei uplift by Northwest Petroleum Bureau,SinoPec,and the onshore marine oil and gas of Paleozoic was discovered firstly in China.The important discovery creates a new domain for hydrocarbon prospecting.Particularly since″the Ninth-Five Year Plan″,Tahe oilfield has been discovered and proved followed by strengthening the exploratory efforts of Paleozoic,gaining a major progression,and establishing an onshore marine petroleum-generating theory of Paleozoic in China.Based on these,profound studies of Ordovician karst and reservoir body are made,revealing basic characteristics of Tahe big oilfield.
