| Abstract: | The relationship between hydrogen index,neutron logging and formation porosity had been introduced simply.The influence of gas and mud filtrate invasion on neutron logging in gas-bearing stratum has been studied.By studying the different effects of mud filtrate invasion to far receiver and short receiver of neutron logging tools,the methods for mud filtrate invasion correcting to neutron logging have been developed,and good result has been given. |

| Keywords: | hydrogen index neutron logging natural gas correcting for mud filtrate invasion |
