静67-59块S3^4段储层评价及有利层优选

The Reservoir Evaluation and Favorable Layer Optimization of S3^4 Submember in Block Jing 67-59,Liaohe Oil Field

根据铸体薄片、扫描电镜、测井等分析和化验资料,对67-59块S43亚段储层特征进行分析和研究。结果表明:该段储层岩性长石砂岩和岩屑质长石砂岩,成分和结构成熟度中等;储集空间以原生粒间孔为主;储集性能中等,非均质性强。结合实际,选用孔隙度、渗透率、含油饱和度和泥质含量作为储层评价参数,应用专家评价法将S34段储层划分为3类,并进一步优选出S43Ⅲ油组-砂岩组为最有利实验目的层。

According to the casting lamella,scan electron microscope and logging analysis and test data,the Block 67-59 of S43 and period of reservoir characteristics are analyzed and studied.The results show that the reservoir lithology feldspar sandstone pac and cutting quality feldspar sandstone,the composition and structure maturity medium;Reservoir space to primary between grains hole for the Lord;Medium reservoir property,strong heterogeneity.Based on the actual,choose the porosity,permeability and oil saturation and shale content as reservoir evaluation parameters,the application of the expert evaluation will sand for three or four reservoir is divided into three classes,and further optimization S43 out Ⅲ oil group for the most advantageous one sandstone group experimental purposes layer.
