基于耦合马尔科夫链的砂岩型铀矿岩性模拟
Lithology Simulation of Sandstone-type Uranium Deposit Based on Coupled Markov Chain
摘要
Abstract
In recent years,methods of revealing the hidden geological conditions has been searched to better serve the prospecting and mining of sandstone type uranium deposits,so more and more scholars pay attention to lithology simulation.In lithology simulation,how to make the lithology simulation results closer to the formation authenticity has been an urgent challenge for scholars at home and abroad.In the continuous research of lithology simulation methods,coupled Markov chain model has been gradually applied to lithology simulation because of its advantages of more accurate simulation results and more real simulated rock direction.Based on the previous studies,this paper introduced an improved coupling Markov chain model lithology simulation method by coupling strength coefficient,and verified that this method can be used for lithology simulation in sandstone type uranium deposits with a case study of Tarangol area.The results showed that this method can not only accurately simulate the authenticity of formation lithology,but also solve the problem of over-dependence on the number of boreholes in the previous methods to a certain extent.关键词
