塔里木盆地碳酸盐岩油气藏勘探潜力及方向探讨

Exploration Potential of Carbonate Reservoir in Tarim Basin

通过对塔里木盆地古生界碳酸盐岩油气藏勘探潜力分析以及塔北、塔中、巴楚隆起成藏条件类比 ,进一步深化了塔里木盆地碳酸盐岩油气成藏规律认识。指出塔里木盆地属于特提斯北缘盆地群 ,宏观油气地质条件优越 ,碳酸盐岩油气资源量丰富 ,勘探领域广 ,层系多 ,资源探明率低 ,勘探潜力大。主攻方向是阿克库勒凸起、雅克拉断凸、和田河凸起。

The understanding of hydrocarbon forming rules of carbonate reservoir is deepened further through analysis of exploration situation and potential of Palaeozoic carbonate reservoir in Tarim basin and contrast of reservoir forming conditions of Tabei, Tazhong and Bachu uplifts. It is pointed out that Tarim basin belongs to Tethys north periphery basin group, where the macroscopic geologic condition is superior, the hydrocarbon resources in carbonate rocks are rich ,the areas of exploration are wide, exploration zones are plentiful, the proved rate of reserve is low, potential of exploration is high. The beneficial areas are Akekule uplift, Yakala fault uplift, Hetianhe uplift, Katake low uplift and Selibuya-mazatage fault buried belt.
