摘　　要：在研究区目的层进行高分辨率层序地层研究的基础上,对分流河道微相的储层质量非均质性进行分析,应用不同级次基准面旋回成因的沉积学分析和表征储层质量非均质性的各项岩芯化验、统计学数据定量分析,指出基准面旋回因素对不同级次水下分流河道主体储层质量非均质性影响存在差异:单一水下分流河道和单期复合水下分流河道的储层质量非均质性呈正韵律变化,多期复合水下分流河道储层质量非均质性分布呈不规则趋势,多级次的基准面旋回及其伴随的可容纳空间变化所引起的沉积环境的变化影响水下分流河道储层非均质性。On the base of high-resolution sequence stratigraphic research of the purpose layer in study area, writers analysis the quality heterogeneity in underwater distributary channel reservoirs. Applicating different base-level cycles of sedimentary analysis and characterization of reservoir heterogeneity of the quality of core test, statistical data analysis, writers pointed out that base-level cycle factors on different levels of underwater distributary channel in the main reservoir quality heterogeneity difference： single underwater distributary channel and single phase composite underwater distributary channel reservoirs quality heterogeneity of positive rhythm changes, multi phase composite underwater distributary channel reservoirs quality heterogeneity of irregulartrend, multi level base-level cycle sand accompanied accommodation changes caused by the change of depositional environment effect the reservoirs heterogeneity of underwater distributary.
