一、前言人工升举是石油工业中的一个重要领域,因为在该领域中大量使用了配有机械和电动设备的装置。而且,涉及改进人工升举方法的新概念和新设想不断涌现。甚至在当前工业不景气的情况下,人工升举技术仍有可能继续发展。这是因为力求改善经济效益的经营者将仍然对降低生产成本以及能帮助降低生产成本的设备有兴趣。但是,当人们还没有认识到来自其它货源的具有相似技术性能的竞争产品时,就很难显
I. INTRODUCTION Artificial ascent is an important area in the oil industry because of the extensive use of devices equipped with mechanical and electrical equipment in this area. Moreover, new concepts and new ideas concerning ways to improve artificial ascent continue to emerge. Even in the current industrial downturn, artificial lift technology is still likely to continue to develop. This is because operators seeking to improve their economics will still be interested in equipment that reduces production costs and helps reduce production costs. However, when people do not recognize competing products of similar technical performance from other sources, they are hard to pronounce
