| 摘 要： | 塔里木盆地塔河地区三叠系圈闭类型多样,主要为复合型.构造圈闭总体上表现为构造幅度低、闭合面积小;岩性圈闭主要受控于相变和砂体尖灭,砂层厚度多在20m以内.三叠系埋藏深度多在4200m以上,埋深大、圈闭面积小、幅度低、岩性圈闭砂体薄、识别难度大、次生油气分布不均匀是目前塔河地区三叠系勘探的难点.通过层序格架的建立、地震振幅属性的深入研究、低幅度圈闭识别、非构造圈闭识别、砂体追踪与对比和沉积微相研究,勘探开发一体化立体勘探等各种手段与方法的应用,在三叠系低幅度与岩性圈闭勘探方面取得显著进展.

| Abstract: | The Triassic traps were multiplex with mainly compounded types in Tahe Oilfield of the Tarim Basin.Structural traps generally were with low amplitude and small close area.Lithologic traps were mainly controlled by sedimentary facies and sands pinchout.The sand thickness of lithologic traps was mostly less than 20 meters.The burial depth of the Triassic mostly was more than 4 200 meters.Deep burial,small trap area,low amplitude,difficult recognition of thin sand layer,uneven distribution of pools were the di... |
