摘　　要：为进一步提高地层对比的精度和储层预测的准确性，以钻井、测井资料为基础，将松辽盆地大老爷府油田泉四段短期基准面旋回划分为向上变深的非对称型、向上变浅的非对称型、向上变浅复变深的对称型和向上变深复变浅的对称型等4种类型。依据可容纳空间的大小，将向上变深的非对称型短期基准面旋回进一步划分为高可容纳空间型和低可容纳空间型；将向上变浅的非对称型短期基准面旋回划分为高可容纳空间型和低可容纳空间型。在此基础上，探讨了每个基本类型及亚类型的沉积背景、叠加样式、岩性特征和沉积动力学过程，总结了短期基准面旋回层序的分布规律，提高了储层预测的准确性。In order to improve accuracy of formation correlation and reservoir prediction, on the basis of drilling and logging data, cyclic sequence of short-term base level in Quan IV Member of Songliao Basin are divided into 4 types, including upward deepening asymmetry, upward shallowing asymmetry, upward shallowing to deepening symmetry and upward deepening to shallowing symmetry. Based on accommodation space, short-term base level cycle of upward deepening asymmetry is further divided into high-accommodation and low-accommodation types, and short-term base level cycle of upward shallowing asymmetry is divided into high - accommodation and low-accommo- dation. Then, sedimentary background, superimposed styles, lithologic features and sedimentary dynamics of each fundamental type and sub-types are discussed, and distribution rules of cyclic sequence of short-term basal level are summarized, improving accuracy of reservoir prediction.
