摘要
针对稀井网区不能采用地质统计学的方法进行高精度储层建模的问题,本文提出了基于地震资料为约束条件的储层建模思路。其主要依据三维地震解释资料和测井重构约束地震反演的预测结果,对储层砂体井间分布和储层物性变化规律进行预测,在预测成果的约束下,采用随机建模的方法,建立了储层三维地质模型。经过现场生产的检验,采用这种建模思路建立的模型能够达到油气田开发阶段的精度要求,同时也为稀井网工区开展储层精细评价提供较好的借鉴。
Because geographical statistics cannot be used in the sparse well net area for reservoir modeling of high accuracy,it is proposed in the paper to simulate the reservoir based on seismic data.The modeling,depending mainly on the three dimensional seismic explanation information and the prediction result of seismic inversion restricted by logging reconstruction,predicts the distribution of reservoir sand across the wells and variation law of the physical properties to build the 3D model of the reservoir under constraint condition with random modeling.This model can help to reach the required accruacy in oilfield development through onsite verification and provide a good reference for precise evaluation of the reservoir in the sparse well net area.
