PRELIMINARY APPLICATION OF FINE RESERVOIR DESCRIPTION TO DEVELOPMENT OF JINGQIU OILFIELD

It is very clear that the heterogeneity of coalbed methane pools were much more obvious comparing with that of natural gas pools,which was resulted from the inhomogeneity of lithotypes of coal and its pore and fracture systems,the changes of surrounding rocks and the hydrology condition.There is much influences on evaluation of exploration strategy and selection of suitable well net for development because of the heterogeneity.The geometry of coal body,the partings and coal facies analysis,the pore and fracture system analyses and the trapping condition analysis are very important contents for study of coalbed methane pools.
