定边地区富县组储层特征

Reservoir Characteristics of Fuxian Formation in Dingbian Area

分析了定边地区富县组沉积相及该储层的基本特征以及非均质型,认为定边地区储层主要受沉积相控制;富县组储层的孔隙类型主要为粒间孔以及粒间溶孔,这两种类型的孔隙为富县组砂岩主要储集空间,并在此基础上对该地区的储层进行了分类.

Sedimentary facies of Fuxian Formation, basic characteristics and heterogeneous property of the reservoir are analyzed. It holds that the reservoir in Dingbian area is mainly controlled by sedimentary facies. Pore types of Fuxian Formation reservoir are mainly intergranular pore and intergranular dissolved pore. Space between these two types of pores is the main space for sandstone. On this basis, reservoir classification is presented.
