摘要
应用岩矿分析技术、压汞技术对鄂尔多斯盆地元城油田元城地区长1油层组的储层微观孔隙结构特征进行研究。研究表明,储层岩石成分复杂,成分成熟度低,结构成熟度低—中等。储层孔隙类型多样,孔隙结构复杂,非均质性较强,微裂缝发育。储层喉道分选系数变化范围较大,有一部分较大喉道存在,最大进汞饱和度较高,退汞效率变化幅度较大。储层微观孔隙结构是各种开发特征的根本原因。
Using the techniques of rock-mineral analysis and Hg injection,the characteristics of reservoir microscopic pore structure in Yuancheng Area of Ordos Basin were studied.Research shows that the component of reservoir rock is complex,the compositional maturity is low and the textural maturity is low to medium.The types of reservoir pores are various,the pore structures are complex,the heterogeneous is strong and the micro fractures are developed well.The range of sorting coefficient of pore throat is wide and some throats are big.The maximal saturation of Hg is high and the range of displacement efficiency is wide.The primary cause of different development characteristics lies in the microscopic pore structure.
