熵作为随机过程中一种不确定性程度的量度,广泛应用在地质学领域。本文应用马尔柯夫链的熵分析方法,分析了邓1-邓5井不同层位地层的系统熵及其各种岩性的前熵、后熵,并推测了各层位可能的沉积相。
Entropy is a non-definability measurement in a random process and it is applied to the role of geology,In this paper,Entropy analysis in Markov chains was applied to analysis the systerm entropy and lithic pre-entropy、 post-entropy in every stratohorizon in Deng 1 to Deng 5 well,and then guessed every stratohorizon probability sedimentray facies.
