通过对冀中地区砂岩油藏厚油层特征的研究，总结出其主要的沉积类型为三角洲前缘相的河口砂坝和滨浅湖相的沿岸滩坝砂。由于沉积方式的不同，各种类型的厚油层层内非均质性及其表现形式有着明显的差异性。采用地质静态和开采动态研究相结合的方法，分析了厚油层层内动用状况及在平面上的分布特点，为油田中后期的调整挖潜指明了方向。
Based on the study of the characteristics of thick reservoirs in the sandstone reservoir in Jizhong area, the paper summarizes the coastal beach bar and sands of the estuarine sand bar and the shallow coastal facies whose main sedimentary types are delta front facies. Due to the different deposition methods, there are obvious differences in the heterogeneity and manifestations of various types of thick reservoirs. By using the method of combining geostatistics and dynamic study of mining, the analysis of the utilization status in the thick oil layer and its distribution in the plane indicate the direction for the adjustment and tapping of the oilfield in the middle and later stages.
