国内外现有的对火山岩储层的研究多数以酸性火山岩为主,对中基性火山岩储层研究比较少,本文作者用遗传算法确定了中基性火山岩储层参数。文中简要介绍了遗传算法的基本原理,具体描述了中基性火山岩体积模型与响应方程的建立以及用遗传算法确定中基性火山岩储层参数的方法原理、特点及程序。利用实际资料进行了模拟计算,效果较好,验证了方法的可行性,为中基性火山岩储层的进一步研究奠定了基础。
Most of the studies on volcanic reservoirs both at home and abroad are mainly acidic volcanics, and there are few studies on the medium-volcanic reservoirs. The authors used genetic algorithms to determine the parameters of the medium-basic volcanic reservoirs. In this paper, the basic principle of genetic algorithm is briefly introduced. The establishment of volume model and response equation of medium-volcanic volcanic rocks and the method principle, characteristic and procedure of genetic algorithm to determine medium-volcanic reservoir parameters are described briefly. The actual data are used to simulate the calculation, the effect is good, which verifies the feasibility of the method and lays the foundation for the further study of the medium-basic volcanic reservoir.
