摘　　要：经过应用高分辨率层序地层学理论方法及结合对取心井岩心观察研究 ,认为本区Es上 2 + 32 砂层组砂体是多期曲流河及辫状河沉积形成 ,该区的泥质隔层、夹层发育 ,存在五个分布范围较稳定的隔层 ,是造成本区纵向非均质性的重要原因 ,本文对处于开发中后期的油田 ,识别储层中的隔层和夹层分布规律 。By using a theoretical method of high resolution sequence stratigraphy and in combination with core observation of coring wells, it is considered that the sandbodies in sand formation of Es_2 upper 2+3 are formed with the deposits of a multiphase meandering river and braid river, where develops muddy restraining barriers and interbeds and exists 5 restraining barriers with more stable distributional range, which is the important cause of longitudinal heterogeneity. For the oilfield development at middle and late stages, the recognition of distributional laws of restraining barriers and interbeds in the reservoirs and finding out residual oil in the reservoir with strong interwell heterogeneity have practical and instructive significance.
