| 摘 要： | 本文以辽河西部凹陷某试验区为例，基于7 口井岩心、镜下薄片、分析测试及400口井测井等多种资料，采取点、线、面相结合的研究思路，利用地质统计学方法，开展稠油热采储层非均质性研究。整体上，于楼油层储层非均质性较强，储层非均质性受沉积作用、成岩作用和构造作用等影响（以沉积作用为主）。单井岩电特征与层内韵律非均质性关系密切，目的层可见3种沉积韵律模式，包括正韵律、反韵律和复合韵律（其中以正韵律和复合韵律为主）。沉积微相空间上的快速变化，导致储层非均质性增强。单层之间隔层分布较稳定，隔层厚度多大于2 m。非均质性强、中、弱的区域大体呈条带状，以北西-南东向展布，与物源方向基本一致。储层非均质性直接影响到了油藏的开发效果，研究储层非均质性可为油藏开发方式的转换提供参考。

| Abstract: | In order to deeply know reservoir heterogeneity and provide the basis for change of development mode of thermal recovery of heavy oil reservoir, heterogeneity of thermal recovery of heavy oil reservoir were studied which taking Yulou oil bearing sets in some experimental area in south end of westward slope of west depression in Liaohe Basin as an example, In this process, geological data and logging data and analysis and testing data were combined and dotted line-plane research approach and geostatistics method were used too. Reservoir heterogeneity were studied from three parts of well and section and plane. Reservoir heterogeneity of aimed stratum in study area were mightiness, and it was effected by three impact of sedimentary function and diagenesis and tectonism. The sedimentary function took the leading role. Well characteristic of lithologies and well-logging properties had intimate relationship with reservoir heterogeneity. There were three types of sedimentary rhythm model of positive rhythm and inverse rhythm and composite rhythm, and positive rhythm and composite rhythm took the leading role. Sedimentary micro-facies were changed quickly in three-dimensional space which lead the strong reservoir heterogeneity. Reservoir heterogeneity were controlled by the sedimentary micro-facies. Interlayer distributed stable between different single layers, and thickness of them were more than 2 m. Different intension of reservoir heterogeneity were extended from north-west to southeast which fit with source direction. Developed results were effected by reservoir heterogeneity, and area with weak reservoir heterogeneity had fine development effect. Research result of reservoir heterogeneity can provide reference to change of development mode of thermal recovery of heavy oil reservoir. |
