摘要
萨北开发区高台子油层主要沉积类型为三角洲前缘相沉积.河口坝是三角洲内前缘相最为活跃的地带,河口坝的识别是三角洲内前缘相沉积的细化或升级.对河口坝和远砂坝微相类型精细识别及剩余油形成机理研究表明：高台子油层由于受浅水强流水动力条件的作用,多发育水下栈桥型河口坝砂体;剩余油主要有3种类型,即河口坝主体纵向韵律性控制的剩余油,不同微相间渗流差异控制的剩余油,渗流屏障控制的剩余油.
Delta front facies sedimentation is mainly distributed in Gaotaizi oil reservoirs of Sabei Development Are- a. The mouth bar is the most active region in the above facies, so its recognition can be regarded as the fine classi- fication and upgrading of the sedimentation. The researches on the fine recognition and forming mechanism of the remained oil show that due to the action of the shallow but strong hydraulic conditions, the underwater stack-type mouth bar sandbodies are well developed in Gaotaizi oil reservoirs ; there are mainly three kinds of the remained oil ： the oil controlled by the vertical rhythm of the main part of the mouth bars, the oil dominated by the seepage differ- ential among different microfacieses and the oil controlled by the seepage barriers.
