2、降分布及油藏模型。同時(shí)研究水平井垂直段井筒流動(dòng)規(guī)律，介紹氣液兩相流模型、流型的劃分及轉(zhuǎn)換；寫物性參數(shù)計(jì)算、垂直井筒流動(dòng)模型計(jì)算和壓降模型計(jì)算。通過對(duì)比，分析，計(jì)算，總結(jié)，最終得結(jié)論。關(guān)鍵詞：水平井；井筒；流動(dòng)型態(tài)；三相流....頁(yè)腳.....頁(yè)眉西安石油大學(xué)高職畢業(yè)設(shè)計(jì)（論文）HorizontalwellchambermobileruleAbstract:Theadvantagesofhorizontalwellshasbecomeanindisputablefactthattoday,actuallytheworld
