摘要

利用铸体薄片、扫描电镜及压汞曲线等资料,系统地研究了安塞油田王窑地区长611储层的岩石学特征、孔隙类型、孔隙结构特征、物性特征及其影响因素,并指出了有利的勘探目标区。综合评价认为:研究区长611 储层砂岩类型以长石砂岩为主,孔隙类型为原生粒间孔隙、溶蚀粒间孔隙、溶蚀粒内孔隙、微裂缝等,砂岩储层的铸体薄片面孔率为0.98%~1.37%,平均孔喉半径较小,为典型的中—低孔、低渗储层;影响储层物性的因素主要为沉积环境和成岩作用。

Abstract

Based on cast thin section, scanning electronic microscope and mercury penetration curves, the petrological characteristics, pore type, pore texture characteristics, reservoir properties and influencing factors of Chang 611 reservoir are systematically studied, and the favorable exploration target areas are pointed out. Through the comprehensive evaluation, it is considered that arkose is the main sandstone type of Chang 611 reservoir, and the pore types include primary intergranular pore, dissolved intergranular pore, dissolved intragranular pore and micro-fracture. The plane porosity of cast thin section of the sandstone reservoir ranges between 0.98% and 1.37%, the average throat radius is low, and the reservoir is of typical middle-low porosity and low permeability. The main factors that influence the reservoir properties are sedimentary environment and diagenesis.
