Abstract: More than 30 years splendid history has been experienced ,the serious prospectingand development situation of natural gas has been facing by Liaohe Oilfield.With the production ofmajor gasfields turning into the late phase ofdevelopment, and stored resources becoming severe shortage, it has beenmore difficult to maintain the stable production.The prospecting direction and objectives of natural gas during the period "11th-Five-Year Plan" is analyzed. The favorable measures to natural gas exploration and development in Liaohe Oilfield include the transformation from"main gas-bearing intervals "to"subtle gas-bearingintervals",thechange fromonshoretobeacharea,the conversionfromconventionalreservoirsto subtle andunconventional gas reservoirs,much attention to be paid for finding the potential of mature area, finding effectively newresources substitution.
