摘要:
为了建立济阳坳陷太古界潜山储集体发育模式,综合运用岩心、测井、试油及露头资料对太古界储集体微观储集空间及宏观分布规律进行研究,认为太古界潜山发育了风化壳和内幕两套储集体,两类储集体形成的主控因素及发育特征有差异。结果表明:风化壳储集体主要受控于断裂改造程度、岩石矿物组成与风化体保存程度等三大因素,潜山顶面岩石矿物组成的差异影响风化壳储集体的平面分布,断裂改造则影响了风化壳储集体的纵向规模,而风化体保存程度控制了风化壳储集体的最终储集性能。内幕储集体主要受控于构造改造程度、岩石矿物组成、潜山岩石结构等三大因素,济阳坳陷太古界潜山岩石矿物组成差异较小,构造改造程度为控制内幕储集体发育程度的最关键性因素,潜山岩石结构为重要的调节性因素。

Abstract:
To establish the reservoir development model of the Archaeozoic buried hill in Jiyang Depression, the microscopic reservoir space and macro distributions of the Archaeozoic reservoir were studied using an integrated analysis of cores, well log data, well testing data and outcrops. It is proposed that the Archaeozoic buried hill has a weathering crust reservoir and an inner buried hill reservoir, with distinct differences in the main controlling factors and development characteristics. The results show that the development level of the weathering crust reservoir is controlled by the deformation degree of the structure, mineral composition and preservation degree of the weathering crust. The difference in the mineral composition of the top surface of the buried hill influenced the horizontal distribution of the weathering crust reservoir. The development degree of the faults influenced the longitudinal scale of the weathering crust reservoir. However the preservation degree of the weathering crust is the determining factor which controls the reservoir properties. The development level of the inner buried hill reservoir is controlled by the deformation degree of the structure, mineral composition and rock structure of buried hill. The Archaeozoic buried hills in Jiyang Depression show little difference in the mineral composition. The deformation degree of the structure is the determining factor which controls the development degree of the inner buried hill reservoir. The rock structure of the buried hill is mainly a regulatory factor.
Key words:  reservoir  Archaeozoic  inner buried hill  weathering crust  Jiyang Depression
