Abstract:The sustaining and rapid economic development in China urgently needs to strengthen oil and gas exploration and development to meet increasing oil demand.The situation of oil shortage is becoming more serious in China,and it is very important to enhance petroleum exploration for giant oilfield discovery and increase hydrocarbon reserves and production.The exploration practice and reserves evaluation show that China has so many sedimentary basins with rich petroleum resources and great exploration potential.The investigation for basic geological features of petroleum resources was made,and the potential of residual petroleum resources were analyzed.The petroleum exploration strategy of "elaborate oil exploration in eastern area,enhance petroleum exploration in western area,advance seas exploration,exploit new areas" and relative measures were put forward.
