After "Sixth-Five", natural gas geology has made great progress on many aspects, such as natural gas formation, natural gas reserves, how to recognize and evaluate natural gas and natural gas pools, the formation conditions and distribution laws on large-medium gas fields. And the natural gas geology has been formed in China. The natural gas re serves increase rapidly based on these achievements from then on. It is very important to think deeply on the problems whether the natural gas resources are well provided and have great potentialities,and on the development prospect and quantitative(even time)evaluation of natural gas resources in order to determine the development strategy of natural gas industry in China.It is very clear that the natural gas resources are not rich in China Based on the research results,exploration practice ans the contrast between the domestic and international resources of natural gas and other fossil fuels(coal,petroleum and so on).But the natural gas exploration is still at a low level and has great potentialities.The duty of natural gas geologic researchers is not to explain whether natural gas and petroleum exist,but to look for the factors how to discover great natural gas pools.It is very important to strength the basis research on natural gas inorder to solve the prolems how to develop natural gas industry. We should take noticeof three problems for the basis research at present,that is ,resources,the pool-formed mechanism and comprehension.Natural gas resource is the important aspect on the basis research on the basis research.We should think highly of conventional ans non conventional natural gas resources.The problems of pool-fprmed mechanism is the forceful point from beginning to end.At the same time ,we should pay attention to the comprehensive reseatch including basis geologic study,new-method and new-technology application.
