长岭气田火山岩储层三维孔隙度建模方法

Three dimensional porosity modeling of volcanic reservoir in Changling gas field

  • 摘要: 建立准确可靠的三维孔隙度分布模型,对火山岩气藏有效储层的预测和建立合理的开发方案具有重要意义。针对长岭气田火山岩储层特点,利用神经网络技术建立单井孔隙度解释模型,并将目的层火山岩划分为三个火山体,提出用火山岩"体控+相控"的建模策略,采用基于象元的序贯高斯随机模拟方法和协同克立金法,建立三维孔隙度参数模型,其结果符合地质认识和生产实际,并为生产单位所采用。

     

    Abstract: To build the accurate and reliable three dimensional po-rosity distribution model accurately is very important to predict volcanic rock effective reservoir and built up reasonable development plan.According to the characteristic of the vol-canic reservoir of Changling gas field,the neural network method has been used to build the individual well porosity in-terpretation model,the volcanics were divided into three vol-canical bodies,and further more,the volcanics and lithology controlled modeling strategy has been put forward to build the porosity distribution model,by using sequential gauss simulation method and Co-kriging method.The three di-mensional porosity parameter modeling has been built up.In result,the porosity distribution model has proved to fit the geological precognition and production reality,which has been applied for production.
