柯克亚油气田的发现和沙参2井的喷油,打开了塔里木盆地油气勘探的新领域,开阔了人们的思路,增强了信心。在我国石油工业中,56万平方公里的塔里木盆地应占据它应有的位置。笔者虽然离开塔里木盆地油气勘探实践已有多年,也确为这新的勘探成果所鼓舞。一、近年来钻井、物探资料不断增加,盆地内部区域构造渐趋明朗。它是在前震旦系基底之上叠置的古生界和中新生界复合盆地,坳陷部位的沉积盖层一般在10公里以上,最厚的可达16公里。根据盖
The discovery of the Kekeya oil and gas fields and the injection of the Shashen 2 well opened up new areas for oil and gas exploration in the Tarim Basin, broadened people’s thinking and enhanced their confidence. In China’s oil industry, the 560,000 square kilometers of the Tarim Basin should occupy its proper place. Although I left the Tarim Basin oil and gas exploration practice for many years, but also indeed inspired by the new exploration results. First, in recent years, drilling and geophysical data have been continuously increasing, and the regional structure of the basin has gradually become clearer. It is a Paleozoic and Mesozoic-Cenozoic composite basin superimposed on the base of the former Sinian. The sedimentary cover of the depression is generally over 10 km and the thickest up to 16 km. According to the cover
