数字岩心技术现状及展望

The current situation and prospect on digital core technology

介绍了数字岩心技术的发展状况,指出了建立数字岩心的既有方法存在的不足,包括过程法无法对复杂的沉积体系进行模拟和随机法建立的数字岩心不具有大范围内的传导性。探讨了数字岩心技术在油田开发领域的应用前景,可用来研究微观渗流机理,模拟岩心驱替实验,预测岩心宏观传导性,评价驱油剂效果,模拟油藏生产动态和确定油气田开发技术政策界限。

The development history of digital core technology was presented. The shortcomings of the existing methods for building digital core were pointed out, which included that process method can't simulate complicated sedimentary system and that stochastic method can't construct digital core with large range conductivity. The application of digital core technology in oilfield development field were discussed, which consist of study on percolation mechanisms, simulation of core displacement experiment, prediction of macroscopic conductivities of the core, evaluation on effect of flooding agent, simulation of reservoir dynamic production and establishment of oilfield developmental technological strategies.
