The commonly developed foreland basins in Central2West China are of the basic ge2 ological conditions of forming large gas provinces and are the major natural gas exploration regions in the future.

The de2 tail statistics of the reserves and production rates in 21 oil2and gas2 bearing basins from 1990 to 2000 are carried out and the natural gas reverse2production change trend is analyzed in the paper. The new2 increased proved gas reserves in place during the ten years were mainly distributed in the central and west regions where they ac2 counted for 43. 58 percent and 36. 29 percent of the total new2in2 creased reserves in the whole country during the same time respec2 tively ,then the offshore and east regions where they made up 13. 08 percent and 7. 04 percent of the total ones respectively. By the end of 2000 ,the residual recoverable gas reserves were mainly distributed in the central and west regions where they amounted to 38 percent and 36 percent of the total residual recoverable gas reserves in the whole country respectively ,then the offshore and east regions where they accounted for 17 percent and 9 percent of the total ones respec2 tively. In regard to the single basin ,the first ten basins of the growth of gas reserves in the 1990’s were Talimu , E’erduosi , Sichuan , Yinggehai ,Chaidamu ,Bohaiwan ,Donghai ,Songliao , Zhunge’er and Tuha Basins. Not only the accumulative proved gas reserves in place but also the residual recoverable gas reserves were of the trend of rapid growth ,but the increase in gas production was relatively slow because of the influence of these factors as market and gas pipeline , etc. ,which restricts seriously the expansion of natural gas industry in China. The present situation of petroleum industry in China can be summarized as follows : serious shortage of reserve oil resources and need for fully expanding the natural gas pipeline and market. The natural gas discovered in China in the 1990’s was of the following characteristics ; ①the new2increased proved reserves in place found in large2sized basins constituted the main body of the new2increased petroleum reserves in place in China in the 1990’s ; ②lithostrati2 graphic traps increased evidently ;and ③the proportion of the im2 portant breakthrough in oil and gas exploration in offshore and fore2 land basins mutiplied.
