sucker rod pump（抽油杆泵）是一种机械采油设备，广泛应用于陆上和海上油田的原油开采。其核心功能是通过地面驱动装置带动井下泵体，将原油从油井底部提升至地面。以下从结构、原理及行业应用三方面详细解析：
系统构成
抽油杆泵系统包含四个关键组件：
工作原理
根据达西渗流定律（Darcy's Law），系统通过周期性的上下冲程实现原油提升： $$ Q = frac{2pi k h (P_e - P_w)}{mu ln(r_e/r_w)} $$ 上冲程时柱塞上行产生负压，固定阀开启吸入原油；下冲程时柱塞压缩液体，游动凡尔开启排油。美国机械工程师协会ASME PTC 30标准提供了完整的效率测试方法。
技术演进
现代智能抽油杆泵系统已集成物联网传感器和边缘计算模块，能够实时监测示功图（Dynagraph）变化。国际石油工程师协会SPE论文库收录的多项研究表明，数字化改造可使系统效率提升15%-20%，同时降低30%的维护成本。
行业应用
该设备特别适用于低渗透油田和成熟油田的二次采油。根据《世界石油》2024年采收率报告，全球在用抽油杆泵超过200万台，其中页岩油井应用占比从2015年的12%增长至目前的35%。中国石油大学（北京）的油田开发实验室持续开展柱塞表面纳米涂层研究，成功将泵效从65%提升至82%。
