摘要
葡北油田葡萄花油层储层物性在平面上的变化,主要是受沉积微相控制。常见的分层位以及不分沉积微相建立的解释模型都不理想,针对该特点在关键井"四性"关系研究的基础上,建立了不同沉积微相约束下的孔隙度、渗透率解释模型。应用解释模型对研究区的267口井进行了二次解释,结果表明,分沉积微相建立的解释模型具有更高的精度,为地质建模和剩余油挖潜研究提供了可靠的储层参数。
In PUTAOHUA formation oil set at Pubei oil field,the change of reservoir physical property on plane was controlled by sedimentary microfacies.The effect of common layering and log interpretation model without classifying sedimentary microfacies was not ideal.In view of this characteristics,this paper established interpretation models for porosity and permeability which were constrained by different sedimentary microfacies,which are built on the basis of the correlation of four reservoir parameters.By using the interpretation models,267 wells in this area are reinterpreted,the result shows that the interpretation models based on different sedimentary microfacies have higher accuracy,and reliable parameters are provided for geologic modeling and remaining oil tapping.
