sucker rod pump（抽油杆泵）是一種機械采油設備，廣泛應用于陸上和海上油田的原油開采。其核心功能是通過地面驅動裝置帶動井下泵體，将原油從油井底部提升至地面。以下從結構、原理及行業應用三方面詳細解析：
系統構成
抽油杆泵系統包含四個關鍵組件：
工作原理
根據達西滲流定律（Darcy's Law），系統通過周期性的上下沖程實現原油提升： $$ Q = frac{2pi k h (P_e - P_w)}{mu ln(r_e/r_w)} $$ 上沖程時柱塞上行産生負壓，固定閥開啟吸入原油；下沖程時柱塞壓縮液體，遊動凡爾開啟排油。美國機械工程師協會ASME PTC 30标準提供了完整的效率測試方法。
技術演進
現代智能抽油杆泵系統已集成物聯網傳感器和邊緣計算模塊，能夠實時監測示功圖（Dynagraph）變化。國際石油工程師協會SPE論文庫收錄的多項研究表明，數字化改造可使系統效率提升15%-20%，同時降低30%的維護成本。
行業應用
該設備特别適用于低滲透油田和成熟油田的二次采油。根據《世界石油》2024年采收率報告，全球在用抽油杆泵超過200萬台，其中頁岩油井應用占比從2015年的12%增長至目前的35%。中國石油大學（北京）的油田開發實驗室持續開展柱塞表面納米塗層研究，成功将泵效從65%提升至82%。
