摘　　要：埋地输油管道易发生腐蚀泄漏,同时伴随着巨大的能源损失,并且对管道周围环境造成污染。根据格子Boltzmann方法的并行运算能力强、算法简单、编程容易等特点,针对埋地输油管道两相泄漏过程中流体流动特征以及两相流体间的相互作用,建立埋地输油管道两相泄漏过程的格子Boltzmann模型,并进行格子Boltzmann算法数值计算前期准备工作,确定数值计算步骤及终止准则。Buried pipeline is very easy to be corroded and leaked, and accompanied with huge energy loss and will do pollution to the surrounding environment. Lattice Boltzmann has the advantages of strong parallel computing capability, simple algorithm, easy programming and so on. In allusion to the flow characteristics of fluid in the two- phase leakage process of buried oil pipelines and the interactions between the two-phase fluids, the Lattice Boltz- mann model of two-phase leakage process of buried oil pipelines is built, and the pre-preparation work for the nu- merical calculation of Lattice Boltzmann method is carried out, and the procedure and the termination criteria of the numerical calculation are determined.
