瓦窑堡新庄区长2储层特征研究

Chang 2 Reservoir Characteristics of Xinzhuang District in Wayaobao

鄂尔多斯盆地三叠纪长2油层组是瓦窑堡新庄区的主力开发层位之一,本文从岩性特征、成岩作用、储层孔隙结构特征、物性特征等方面,对研究区长2油层组的储层特征进行分析。通过研究结果表明,本区长2储层的孔隙主要为残余粒间孔,其次为次生溶蚀孔隙,成岩作用强烈,物性较差,是典型的低孔-特低孔低渗储层。

Ordos basin, the Triassic Chang 2 reservoir is one of the main development horizon in Xinzhuang district of Wayaobao. Based on the lithology, diagenesis, reservoir pore structure characteristics, physical characteristics, etc., the reservoir characteristics of Chang 2 reservoir group is analyzed. The research result shows that in this area, Chang 2 reservoir pore are mainly the residual intergranular pore, secondary dissolution pores, followed by strong diagenesis, poor physical property, is a typical low hole, very low permeability reservoir.
