Abstract:

Both China's reserves and production of natural gas have been growing rapidly in recent years. It is forecasted that China will have more gas production than oil before 2030 with the consideration of global development trend of natural gas and in comparison with the natural gas development history of U.S. On the basis of analysis of China's oil and gas development history, a new thinking about oil and gas exploration is proposed, that is, the hydrocarbon generation research is broaden from peak period to overall process, more attentions from good reservoir to multi-type reservoir and exploration from local traps to large area or total basin. Furthermore, the most important reason for gas production surpassing the oil is that the occurrence of natural gas is far more than that of oil in the nature, and the boom of unconventional natural gas promotes great change of exploration thinking; breakthroughs in fine three-dimensional seismic, horizontal well staged fracturing and other core technologies broaden the horizons of exploration. In addition, the paper proposes that hydrocarbon generation and conservation conditions are the most important factors in the future exploration and change of exploration thinking will certainly bring substantial increase of resources and great broadening of exploration field.
