五十年代,塔里木盆地北部边缘的库车坳陷中,首次发现了产层为侏罗纪砂岩的依奇克里克油田,证明这是一个含油气盆地。七十年代后期,又在西南坳陷发现了产层为第三纪砂岩的柯克亚油气田。八十年代初,又在盆地北部的塔北隆起上打出了一口高产油气井——沙参2井。这三个重要发现,说明不仅盆地的边缘坳陷产油,盆地内部也产油;不仅中、新生代地层产油,古
In the 1950s, for the first time in the Kuqa Depression on the northern edge of the Tarim Basin, the Ichiklik field with Jurassic sandstone was identified as a petroliferous basin. In the late seventies, the Kekeya oil and gas field with the third-generation sandstone was found in the southwestern depression. In the early 1980s, a well of high-yielding oil and gas wells, namely, Shashen 2 was hit on the northern Tabei uplift in the basin. These three important discoveries show that not only oil production in the marginal depression of the basin but also oil production in the interior of the basin; not only oil production in the Mesozoic and Cenozoic strata,
