掌握流體在多孔介質(zhì)中得流動規(guī)律是油藏工程領域得一個基本問題。對油藏中壓力分布以及流量隨時間的變化進行仔細分析和模擬能夠幫我工程人員了解流體在多孔介質(zhì)中得輸運動態(tài)。單相滲流模型是描述多孔介質(zhì)滲流過程最簡單的模型,雖然理論上較為簡單,該類模型常用于油氣田開發(fā)早期的流動模擬計算或簡化的流動分析場合。本文介紹了課題組內(nèi)的2維單相滲流數(shù)值模擬器的基本原理并編程實現(xiàn)了計算過程。滲流方程組采用有限差分法離散,并采用Stone提出的強隱式解法求解滲流方程。數(shù)值模擬器采用MATLAB編程實現(xiàn),其計算可應用與可壓縮流和微可壓縮流。為了驗證計算結果的正確性,分別驗證了時間步長內(nèi)的物料守恒和累計物料守恒,顯示了計算結果的正確性。
