摘要
The marine carbonate reservoir in Tazhong uplift in Tarim Basin is characterized by complicated geology and surface conditions. After 15-year researches and practices, the hydrocarbon accumulation theories for marine carbonate reservoirs have been developed. By means of these theories and technologies, a billion-ton-grade condensate gas field of the Ordovician carbonate reservoirs in Tazhong uplift has been found out. Also, a large scale condensate gas field with interlayer karst of Yingshan Formation in the northern slope of Tazhong uplift has been discovered.
