摘　　要：实际取样的岩心,实验耗时长,且由于很多岩石实验对岩心有一定损害,必然给下一个实验带来困难和误差。由于数字岩心是对实际岩样的数值模拟,所以数字岩心模型可以替代实际岩心用于研究储层的微观因素。这不仅克服了实际取心困难、样本少的难题,更解决了同一岩心数据多样性的问题。随着计算机的发展,数字岩心技术也在不断进步完善,数字岩心模型的建立也有了更多的方法与应用。各种方法有其优缺点,在针对不同的问题需要选取合适的方法获取模型。综合国内外的发展提出今后数字岩心技术发展趋势。The experiments in objective core samples will take much time and some of it will damage the core,then make the next experiment more difficult and some errors.Digital core can numerically simulate the objective core,so it,substituting for objective core,would be used for researching the microcosmic elements of reservoirs.This overcome some problems,such as the difficult of gaining cores,absence of core data,and solve the difficult that was the various data to one core.With the computer technology developed,the digital core technology is gradually improved.So constructing digital core have many methods and applies.All kinds of methods has its merits and drawbacks so we need choose adequate method for getting core simulation.According to the development at home and abroad,the future development trend of digital core technology is put forward.
