摘要
岩石渗透率作为岩石固有的物性参数,对于研究流体在岩石中的渗流过程具有重要意义;然而传统的研究方法只是在数值方面的计算,并未结合流体的实际流线。通过结合传统计算方法与数字岩心技术,使用Avizo三维重建软件对渗透率的计算结果与流线结合可视化结合处理,可清晰观察到流体流动流线及流体渗透压力分布;并得到渗透率张量的计算结果。可从流线观察得到岩石渗透率的各向异向。通过与实验室岩心所测量结果相对比,发现二者误差极小,说明重建结果可信,可用于工程实际计算。通过对数字岩心进行三维模拟,可以使研究者得到更为直观的结果,有利于进行更加客观的分析,为油藏工作者分析岩石物性参数时提供了一种新的方法。
As an inherent physical parameters,the rock permeability is important for the study of fluids in the rock seepage process. By combing the traditional calculation method and digital core technology,the Avizo software is used to visualize the results of permeability. The flow line and permeability pressure can be clearly observed. By comparing with the results of laboratory,the error of the two is very small which means the simulation is reliable and that can be used for engineering calculation. Through the study of three-dimensional simulation of digital core,researchers can make more intuitive results and it's conducive to a more objective analysis. This provides a new method for reservoir workers to analyze the rock physical property parameters.
