| 本文研究海平面变化对海相单一亚相储层宏观非均质性的影响。以经典层序地层学理论为指导，应用岩心测试、测井数据，对哈得油田东河砂岩段临滨亚相储层宏观非均质性进行了分析，提出了海平面升降对临滨亚相储层宏观非均质性控制机理，确定了海平面相对变化控制的储层宏观非均质性分布模式。结果表明，准层序、准层序组及体系域内不同级次的海平面变化，对沉积物形成的水动力条件及沉积后所处表生环境产生较大影响，各项储层宏观非均质参数表现出明显的规律性，使准层序内单一临滨亚相储层宏观非均质性表现为向上减弱的变化趋势；准层序组内由于准层序堆砌特征差异，使退积式准层序组内临滨亚相储层宏观非均质性呈向上变强的特征，而进积式准层序组内表现为由强到弱的趋势；高位体系域内单一临滨亚相储层宏观非均质性总体表现为向上逐渐减弱。 |

| This work studies the influence of sea level change on the macroscopic heterogeneity of single marine subfacies reservoirs of the Donghe sandstone shoreface subfacies in the Hadeson oilfield. Our study is based on core testing and well logging data, guided by the theory of classical sequence stratigraphy. The control mechanism of sea level rise and fall on the macroscopic heterogeneity has been proposed and the distribution pattern of reservoir macroscopic heterogeneity controlled by the relative sea level change has been determined. The results show that different orders of sea-level change in parasequence, parasequence group and system tracts have a greater impact on the hydrodynamic conditions of sediment formation and post-depositional environment. The reservoir macroscopic heterogeneity parameters show obvious regularities, which make the macroscopic heterogeneity of the single shoreface reservoirs in parasequence characterized by weaker heterogeneity upward. Because of the parasequence accumulation characteristic differences in the parasequence group, the macroscopic heterogeneity of shoreface subfacies reservoirs is characterized by being stronger upward inside the retrogradational parasequence group. While inside the progressive parasequence group, it changes from strong to weak upward. In HST, the macroscopic heterogeneity of single shoreface subfacies reservoirs has a general trend becoming weaker upward. |
