在塔里木盆地东部英吉苏坳陷钻探的华英参1井,发现了含油的三叠系,并证实中、下侏罗统煤系有良好的生烃条件。英吉苏坳陷的形成经历了早期拱张裂陷、中期挤压改造、晚期稳定覆盖等三个阶段,具有类前陆盆地的三分性地质结构,油气资源潜力大;预测它是由四个含油气系统、四大断裂构造复式油气聚集带组成的大型成油体系,中央挤压断裂带油气最富集,建议应继续加强勘探。
The Well Huayin 1 drilled in the Yingjisu Depression in the eastern Tarim Basin discovered the oil-bearing Triassic and confirmed the good hydrocarbon generation conditions of the Middle and Lower Jurassic coal measures. The formation of the Yingjisu Depression has experienced three stages of early arching, medium-term extrusion alteration and late stable covering. It has the tridimensional geological structure of the foreland basin and has great potential for oil and gas resources. It is predicted to be composed of four Oil and gas system, and the four major oil and gas accumulation zones composed of multiple oil and gas accumulation zones with fault structures. The oil and gas in the central extrusion fracture zone is the most abundant, suggesting that exploration should continue to be strengthened.
