郝家坪地区长2储层非均质性及其控制因素分析

Research on Reservoir Heterogeneity of Chang 2 in Haojiaping Area of Ordos Basin

讨论杏子川油田郝家坪地区长2储层的非均质性特征,分析沉积环境及成岩作用对该区储层非均质性的控制作用。研究表明,长2储层层内及层间储层非均质性强,平面上非均质性不强,受沉积环境及成岩因素的影响,区内储层非均质性变得复杂。

The heterogeneities of Chang 2 reservoir at north of Haojiaping area were studied in this paper,and the effect and controlling factors of the sedimentary environments and diagenesis on heterogeneities were also analyzed.The results show that there are strong interlayer heterogeneity and strong in- layer heterogeneity,but weak planar heterogeneity of Chang 2 reservoir in the study area; and the reservoir heterogeneity of this area is aggravated due to sedimentary environments and diagenesis.
