【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)運行費用,提高SAGD技術采油的整體經(jīng)濟效益,成為SAGD技術應用中急待研究的課題。針對這一問題,本文研究了余熱綜合利用的技術方案,列舉了三個熱能利用方案進行對比,優(yōu)選出最佳的換熱方案。對主要設備進行了選型分析,結合兩種換熱介質的物性特點,推薦了最適合本方案的換熱器類型。對換熱面積進行了計算,確定了換熱器的換熱面積和換熱器臺數(shù)。對全流程管線保溫方案進行了優(yōu)化設計,并通過計算,得出保溫層經(jīng)濟厚度。并對整個技術方案的經(jīng)濟性及環(huán)保性進行了分析。
