调优或革新方法使人工升举技术获得了独特的进展。要扩大一种无可辨驳的升举装置的优点，需有革命性的设计理论来获得理想特性，这是研制超长冲程抽油装置的构思（ULSPS）
Tuning or innovating methods have made unique advances in artificial lift technology. The need to expand the merits of a non-discernable lifting device requires revolutionary design theory to achieve the desired properties, which is the concept of developing an ultra-long stroke pumping unit (ULSPS)
