Petrophysical facies characteristics and classification evaluation of Dongying Formation of Nanpu No. 4 structure

  • 摘要: 南堡凹陷4号构造晚期成岩作用强烈、储层非均质性强、孔隙结构复杂,导致优质储层岩石物理特征不清及储层有效性评价难. 针对这一难题,综合利用岩心薄片鉴定、扫描电镜、X全岩衍射、毛管实验及测录、试油等数据对储层的沉积特征、成岩特征及孔隙结构特征开展相控研究,研究结果表明研究区东二、东三段沉积相主要发育辫状河三角洲相,沉积微相主要发育水下分流河道、分流间湾、河口坝等;依据成岩作用及矿物类型将成岩相划分为弱溶蚀相、黏土矿物充填相、碳酸盐胶结相、压实致密相四类;根据储层物性及压汞等数据将孔隙结构相划分为Ⅰ类大孔粗喉型、Ⅱ类大孔中喉型、Ⅲ类中孔细喉型、Ⅳ类小孔微喉型. 基于沉积、成岩、孔隙结构三种特征单元叠加聚类分析将储层岩石物理相划分为PF1-PF4四类,其中PF1为油气及油水产能高的优势储层,PF2为产能一般的含油储层,PF3为需要储层改造才有产能的较差储层,PF4为无效储层,通过测井响应规律建立岩石物理相分类评价标准,为研究区储层有效性评价、优势储层预测以及后续的滚动开发提供了技术支撑和坚实的理论基础.
