综合应用地震、地质和测井资料预测储层分布
|
摘要
提出了在开发设计阶段预测储层分布的新方法。新方法利用地质统计学技术将地震孔隙度反演数据、测井孔隙度初始模型与地质综合研究成果相结合 ,最终形成储层孔隙度模型 ,从而预测储层的分布。该方法综合应用了地震、地质和测井等各种基础资料 ,克服了常规储层预测只注重地震资料的缺陷 ,它对于构造较复杂、储层非均质性较强的油田的储层预测比较有效。应用该方法对渤海南堡 35 - 2油田的储层进行了预测 ,预测结果与地质认识基本相符
This paper presents a new method to predict reservoir during development planning of oil and gas fields.By geostatistic techniques,this method can integrate inversion data of seismic porosity,initial model of logging porosity and results of geological study into a reservoir porosity model,by which reservoir distribution may be predicted.It is an effective method for reservoir prediction in oil fields with complex structures and higher heterogeneity,owing to using various kinds of basic data (i.e.seismic,geological and log data) to avoid shortcomings from only using of seismic data in conventional reservoir prediction.In Nanpu 35 2 field,Bohai Sea,this method was applied,producing reasonable prediction results in accordance with geological knowledge.
