【摘要】 塔里木盆地巴楚—麦盖提地区志留—泥盆系油气勘探新发现表明,该区勘探前景广阔,急需对其岩相古地理进行精细研究。通过对塔里木盆地巴楚—麦盖提地区志留—泥盆系露头剖面、钻井岩心及测井等资料的系统分析,综合各层位砂体及地震相平面展布等特征,恢复了研究区志留—泥盆系组级地层单元的岩相古地理面貌。分析认为研究区南部志留—泥盆系发育4套有利的储盖组合,预测研究区西南部巴参1—康1—方1井区和东南部和田1—和4—巴东2井区为有利勘探区带;下志留统柯坪塔格组、中下泥盆统克孜尔塔格组和上泥盆统东河塘组为主要目的层位。更多还原

【Abstract】 Great potential for petroleum exploration has been proved in Silurian—Devonian of Bachu—Maigaiti region,the Tarim Basin.The studies of lithofacies and paleogeography are very necessary.According to outcrop profile,core sample and logging data,combined with the distribution of sandbody and seismic facies,the lithofacies and paleogeography of the study area have been recovered.4 sets of favorable reserve—cap assemblage have been identified in Silurian—Devonian in the south of the study area.Well regions BC1—K1—F1 in the southwest and HT1—H4—BD2 in the southeast are favorable for exploration.S1k,D1-2k and D3d are the main intended interveals.更多还原
