文昌HDB油田ZH1-2L油组储层非均质性综合研究
Petroleum Geology and Engineering（2016）
Abstract
文昌HDB油田ZH1-2L油组能量不足,采油速度及采出程度低,需要进行储层非均质性分析.ZH1-2L油组以粉、细砂岩和泥质粉、细砂岩为主,砂岩与泥岩多呈薄互层,为中-高孔中低渗储层,储层非均质性严重,储层内部泥质夹层发育,从平面、层内、微观三方面对ZH1-2L油组储层非均质性进行分析,得出该油组砂体厚度稳定分布,平面较均质,储层层内为非均质—较均质型,运用岩心实验分析中铸体薄片分析法和毛管压力曲线法,得出ZH1-2L油组储层微观非均质性强,微观孔喉结构发育差.
