掌握流體在多孔介質(zhì)中得流動(dòng)規(guī)律是油藏工程領(lǐng)域得一個(gè)基本問題。對(duì)油藏中壓力分布以及流量隨時(shí)間的變化進(jìn)行仔細(xì)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(yùn)動(dòng)態(tài)。單相滲流模型是描述多孔介質(zhì)滲流過程最簡(jiǎn)單的模型,雖然理論上較為簡(jiǎn)單,該類模型常用于油氣田開發(fā)早期的流動(dòng)模擬計(jì)算或簡(jiǎn)化的流動(dòng)分析場(chǎng)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(shí)現(xiàn)了計(jì)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(qiáng)隱式解法求解滲流方程。數(shù)值模擬器采用MATLAB編程實(shí)現(xiàn),其計(jì)算可應(yīng)用與可壓縮流和微可壓縮流。為了驗(yàn)證計(jì)算結(jié)果的正確性,分別驗(yàn)證了時(shí)間步長內(nèi)的物料守恒和累計(jì)物料守恒,顯示了計(jì)算結(jié)果的正確性。
