摘要
为深化加拿大麦凯河油砂SAGD开发,分析储层成岩作用,准确划分麦克默里组储层的成岩阶段,以岩心分析化验资料为基础,综合运用了铸体薄片、扫描电镜、粒度分析资料进行研究。研究结果表明:麦凯河油田上麦克默里组岩性为中-细石英砂岩、中-细岩屑砂岩,储层的压实作用发育极差,处于弱胶结-未胶结状态,交代作用和溶解作用发育,综合分析麦凯河油田上麦克默里组储层处于同生成岩阶段至早成岩阶段A期,是极为优质的油气储层。
In order to deepen the SAGD development of Mackay River oil sands in Canada,this paper analyzes the diagenesis of reservoirs and accurately divides the diagenesis stages of McMurray formation reservoirs.Based on the core analysis and laboratory data,the paper studies cast thin sections,scanning electron microscopy,and grain size analysis data.The result shows that the lithology of upper McMurray formation in Mackay River Oilfield is medium-fine quartz sandstone and medium-fine lithic sandstone.The compaction of the reservoir is extremely poor,and it is in a weakly cemented-uncemented state.The metasomatism and dissolution are well developed.Through comprehensive analysis,the upper McMurray formation reservoir in Mackay River Oilfield is found to be in a period from syngenetic stage to early diagenetic stage A,which is an extremely high-quality oil and gas reservoir.
