克拉玛依油田五八区二叠系储层控制因素及分类评价

KARAMAY FIVE EIGHT OIL FIELDS IN THE PERMIAN RESERVOIR'S CONTROLING FACTORS AND CLASSIFICATION EVALUATION

储层控制因素包括古构造背景、沉积相带、成岩作用类型及古地温场等因素,克拉玛依油田五八区二叠纪同沉积断裂发育,断裂对扇体的控制作用明显,从宏观上控制着储集体的发育与分布,其次,沉积微相控制着油气藏储集体的规模。基于研究区近30口的取心井岩心、录井及测井数据,运用显微镜、扫描电镜等手段,开展二叠系上(下)乌尔禾组、风城组、佳木河组等层组的储层物性特征、孔隙类型、压汞参数、成岩作用特征、孔隙结构研究及描述,建立了适合研究二叠系碎屑岩储层评价分类标准,并对储层进行了分类评价。

Controlling factors of reservoir include ancient tectonic background,sedimentary facies belt,the Cheng Yan effect factors and types of paleo geotemperature field.Karamay five eight oil fields in the Permian syndepositional faults development,controlling effect of faults on the fan body is obvious,which controls the development of reservoir and distribution of its time from the macro,and sedimentary microfacies control the hydrocarbon hidden reservoir scale.Core analysis,logging and logging data from the study area are based on nearly 30 wells,using microscope,SEM and other means,to carry out the study on the upper Permian(lower),Wuerhe Fengcheng group,such as group of Jiamuhe group layer of reservoir physical properties,pore types,mercury injection parameters,Cheng Yan function feature,pore structure and its description,then established the evaluation standard of classification for the study of Permian clastic rock reservoir,and conducted the reservoir classification and its evaluation.
