【摘要】：我國遼河油田自采用SAGD(Steam Assisted Gravity Drainage,簡稱SAGD蒸汽輔助重力泄油)技術(shù)開采稠油以來,地面井口采出液的溫度大幅度提高,溫度高達(dá)170-180℃,較高的井口采出液溫度引起了較大的剩余熱能。如何有效地回收和利用剩余的熱能,降低生產(chǎn)運(yùn)行費(fèi)用,提高SAGD技術(shù)采油的整體經(jīng)濟(jì)效益,成為SAGD技術(shù)應(yīng)用中急待研究的課題。針對(duì)這一問題,本文研究了余熱綜合利用的技術(shù)方案,列舉了三個(gè)熱能利用方案進(jìn)行對(duì)比,優(yōu)選出最佳的換熱方案。對(duì)主要設(shè)備進(jìn)行了選型分析,結(jié)合兩種換熱介質(zhì)的物性特點(diǎn),推薦了最適合本方案的換熱器類型。對(duì)換熱面積進(jìn)行了計(jì)算,確定了換熱器的換熱面積和換熱器臺(tái)數(shù)。對(duì)全流程管線保溫方案進(jìn)行了優(yōu)化設(shè)計(jì),并通過計(jì)算,得出保溫層經(jīng)濟(jì)厚度。并對(duì)整個(gè)技術(shù)方案的經(jīng)濟(jì)性及環(huán)保性進(jìn)行了分析。
