1、水平井井筒流動(dòng)規(guī)律研究水平井井筒流動(dòng)規(guī)律研究摘要:水平井的優(yōu)越性如今已成不爭(zhēng)的事實(shí),世界在短短幾年中竟相鉆成數(shù)千口水平井就是證明。在水平井實(shí)際生產(chǎn)時(shí),井筒流動(dòng)和油藏滲流是一個(gè)和互影響、相兀作用體,合理描述水平段的流體流動(dòng)規(guī)律和壓降關(guān)系及垂直段流體流動(dòng)規(guī)律,對(duì)確定水平段的長(zhǎng)度、準(zhǔn)確預(yù)測(cè)水平井產(chǎn)量等冇重要意義。合理準(zhǔn)確的掌握水平井井筒流體流動(dòng)規(guī)律,不僅對(duì)水平井的生產(chǎn)及生產(chǎn)過程中調(diào)整有著重要的指導(dǎo)意義,而11對(duì)汕藏整體的合理開發(fā)捉供著重要的依據(jù)。研究水平井井筒壓力分布、井筒流態(tài)及井筒壓降模型;介紹水平井壓降分布及油藏模型。同時(shí)研究水平井垂直段井筒流動(dòng)規(guī)律,介紹
