摘　　要：目前，四川盆地内已完成钻井数千口，发现气田近百个，年产气量超过８０亿立方米。在分析天然气勘探现状的基础上，对该盆地内的天然气勘探接替区块进行了综合论证。提出主要烃源体系展布、古构造发展及断裂发育是接替区块必备的三个条件。据此，对该盆地内Ｊ１、Ｔ３、Ｐ２、Ｐ１、Ｓ１、Ｃ１六套烃源层所制约构建的９组自源型、异源型烃源体系进行了讨论。将“稳定东部、开拓西部”，“稳定中层、开拓浅深”作为盆地中近期勘探原则。将川西、川东北、川南及川东西南段等区域内的特定区块列为四川盆地天然气勘探战略接替区块。At present,in Sichuan Basin,several thousands of wells have been drilled,near one hundred of gas fields have been found and yearly gas production has reached seventy hundred million cubic metres.Based on analyzing the present situation of natural gas exploration,a comprehensive demonstration about the replaced tracts for natural gas exploration in the basin is done.It is proposed that the main hydrocarbon source system distribution,palaeotectonic evolution and fault development are the three conditions necessary for the replaced tracts.According to this,a discussion on the nine groups of the authigenic and allogenic hydrocarbon source systems restricted and constructed by six sets of hydrocarbon source formations(J 1,T 3,P 2,P 1,S 1 and C 1)in the basin is carried out.“Stabilizing east part and opening up west part”and“Stabilizing middle strata and opening up the shallow and deep ones”are taken as the mid and short term exploration principles of the basin,and some specific tracts in West Sichuan,Northeast Sichuan,South Sichuan and the southwest part in East Sichuan are listed as the strategic replaced tracts for natural gas exploration in Sichuan Basin.
