摘要
通过对塔中4油田CⅢ油组含砾砂岩段储层测井、录井、岩心和试油等资料的收集、整理、校正、分析,针对含砾砂岩段,开展了储层特性和油水层解释标准研究,分析储层岩性、物性特征及关系,讨论了微观孔隙结构特征对储层物性、电性的影响,岩性和胶结物的变化对含砾砂岩段储层物性、含油性、电性的影响。通过物性、饱和度分析资料、毛管压力曲线资料、录井和薄片含油性产状描述资料,以及测试分析等资料,着重讨论了含砾砂岩段储层的油层、水层及干层识别的下限值确定方法,建立了储层油、气、水、干层的解释标准及解释图版,为储层参数模型建立和油气层识别打下了坚实的基础。
According to the collection,correction and analysis of data of well logging logs ,cores and formation test in the gravel-bearing sandstone reservoirs of CIII oil formation,the research on the characteristics of gravel-bearing sandstone reservoirs and interpretation standard of oil-water zone were studied,the effect of lithology and cement changes on physical property,oiliness and electrical property of sandstone reservoir were discussed.By describing the physical property and saturation analysis data,capillary pressure curve data,logging and thin section ,oiliness occurrence description data,and test analysis data and so on,the method for determining reservoirs,water layer and dry layer of gravel-bearing sandstone reservoirs was put forward,interpretation standard and interpretation chart of oil,gas and dry layer were established.It provides a solid foundation for reservoir parameter model building and hydrocarbon reservoir identification.
