【Abstract】 This paper analyzes three key strategic oil and gas target areas selected by PetroChina, i.e.: Hetao basin, Tadongnan (southeastern Tarim) depression and Qiangtang basin. They are characterized by abundant oil and gas resources and provided with the oil and gas resources basis for strategic area selection. Then the paper discusses the combination of reservoir and seal and oil and gas showings. All the three areas have essential oil and gas accumulation-forming conditions and better petroleum prospects though each area has its unique features. Finally some suggestions about the exploration are proposed on the basis of an analysis of the main problems concerning exploration of the three target areas.更多还原
