摘要
目前火山岩储层的夹层分布特征研究处于探索和初级定性描述阶段,几乎没有定量的区分技术手段,因而,在低渗透薄储层火山岩气藏有效开发过程中,夹层的识别成为一个新的热点和难点。在分析了克拉美丽气田滴西17井区火山岩气藏储层及其夹层特征的基础上,利用分频属性反演与模型正演相结合的方法能够有效识别出火山岩储层中夹层及其展布特征,而且大大提高了地震的纵横向分辨率。将该方法应用于火山岩储层的开发实践中,取得了很好的应用效果,且对于火山岩气藏夹层识别方法的推广及指导油气藏开发具有重要的意义。
The study of distribution characteristics of the interlayer in volcanic reservoir was at an exploratory and qualitative description stage,there was few means of quantitative distinguish,so in the process of effective development of low permeability thin volcanic gas reservoirs,interlayer identification was a new hotspot and difficulty.Based on analysis of volcanic reservoir and interlayer of Wellblock Dixi 17in Kelameili Gasfield,the method of frequency-divided attribute inversion combined with forward modeling method could effectively identify the interlayer of volcanic reservoir and its distribution characteristics,and it greatly improved the vertical and horizontal resolution of seismic inversion.The method is used for volcanic reservoir development,good application effect is obtained,it is of great significance for popularizing the interlayer identification in volcanic gas reservoirs and for guiding the gas reservoir development.
