Abstract: Pu 67 block is special condensate gas reservoirs,which feature buried deep depth,low permeabili-ty and difficult producing,At present,the recovery percent of reserves is very low,and the developing result is bad. Through study on the distribution law of remaining natural gas in Pu 67 block,the direction of further tapping production potential was determined for the remaining gas,the matching tapping production potential technology was studied to solve the problems in gas reservoirs development,which achieved better production increasing results in the field application.
