摘要

摘要: 利用测井、岩心、薄片、物性分析及压汞资料，对叙利亚O油田上白垩统Shiranish组碳酸盐岩储集层特征及主控因素开展研究，明确生屑滩灰岩和粉晶云岩为研究区主要储层类型，其沉积环境、储集空间、孔渗性能及孔喉结构均不相同。生屑滩灰岩储层以组构选择性孔隙为主要储集空间，具有良好的孔喉结构，储渗性能好，其形成主要受沉积相带及多期溶蚀作用控制；粉晶云岩储集层包括选择性组构孔隙和非选择性组构孔隙2种类型，具有中高孔、高渗特征，其形成主要受大断裂和白云石化作用的影响。

Abstract: The reservoir characteristics and controlling factors of the Cretaceous Shiranish Formation in O oil field in Syria were studied using petrophysical logs, core samples, thin sections, physical properties and mercury penetration data. Two types of reservoir rocks were identified:limestone reservoir developed in bioclastic shoal microfacies and silt-sized crystalline dolomite. They are different in depositional environment, reservoir type, storage space, physical properties and pore structure. Limestone reservoirs with selective texture pores have good pore structure and physical properties controlled by sedimentary facies and multi-phase dissolution. Silt-sized crystalline dolomite with both selective and non-selective pore textures is of medium-high porosity and high permeability controlled by large fault systems and dolomitization.
