济阳坳陷河流相储层物性演化影响因素研究

The Research of Influence Factors on Reservoir Physical Evolution of Fluvial Facies in Jiyang Depression

济阳坳陷新近系河流相广泛发育,储藏了丰富的油气资源。通过研究胜利油区河流相储层相关录井、测井、岩芯、薄片和物性资料,确定了工区河流相储层的岩性、物性特征。首先有针对性地设计了几组物理模拟实验,验证物源、埋深等对储层的影响。结合前人研究的部分成果,认为物源组成是影响河流相储层物性差异的因素之一,但该因素对储层演化过程中的作用还有待进一步研究。然后对目前河流相储层研究中的一些问题进行了深入剖析,确定了成岩作用类型和成岩期次。

Fluvial facies is widespread in Shengli oildom in Neogene times, which has preserved rich oil &gas resources. We confirmed lithology &physical properties of fluvial facies of work area through logging, core, slice and other related data. First we designed several physical analogue experiments to validate the influences of source and depth on reservoirs. Combined with some of the previous research results, we concluded that source composer is one of the factors influencing reservoirs of fluvial facies, but details of influences on the process of reservoirs evolution need further studies. Then we anatomized some issues of fluvial facies reserves research, and confirmed digenesis types and periods.
