为了在四川省盐源地区寻找煤炭资源,得出该地区聚煤规律,以卫星遥感、实测地层剖面、钻探、测井及相关测试为主要手段,运用沉积学、煤田地质学的基本理论和方法,分析了盐源地区龙潭组沉积环境及其演化、聚煤规律,在龙潭组识别出潮汐三角洲平原相及潮坪沉积相。研究结果表明:三角洲平原的泥炭沼泽及潮间泥炭坪为盐源地区较有利的聚煤环境;同时,根据研究区地层、构造、聚煤特征、煤层、地形地貌等条件,在小高山及盖祖-桃子含煤远景区圈定了3个重点含煤区——和坪子、中梁子、桃子重点含煤区,为该区下一步勘查工作提供了有利靶区,并为在四川西部二叠系的找煤工作提供依据。

In order to search coal resources in Yanyuan Area of Sichuan Province and to have the coal accumulation law of the area,basedon the satellite remote sens ing technology,site measurement of strata profil,drilling exploration,logging and related tests as the mainmeans,the basic theory and method of the sedimentology and coa lfield geology were applied to analyze the sedimentary environment,evolu-tion and coal accumulation law of Longtan Formation in Yanyuan Area. A tidal delta and tidal flat sedimentary facies were distinguished inLongtan Formation. The study results showed that the peat swamp of the delta plain and intertidal peat flat would be the favorable coal ac-cumulation environment in Yanyuan Area. Meanwhile, according to the strata, tectonic,coal accumulation features,seam,topography andother conditions of the study area,three important coal bearing areas of Hepingzi,Zhongliangzi and Taozi coal bearing areas were set up inXiaogaoshan and Gaizu-taozi Coal-Bearing Prospective Area s. Thus those areas would provide favorable target area for the further surveywork and could provide the basis to search coal resources in the Permian at Western Sichua
