摘要
报道油田井口装置中的最新专利产品的技术特点、结构原理、应用效果及经济效益。抽油井口随动对中光杆密封器的独特之处是：在抽油机运行过程中能与光杆随动调偏对中，从根本上解决光杆密封器被偏磨而引起的一系列严重问题，并且具有停抽头并及防盗等功能。
Servo-aligning sealer for polished rod at wellhead is a new patented product. This paper emphat- ically describes the technical features and structural principle of this product, as well as the effective- ness and benefits brought by this product. The unique feature of this preduct is that, in the operation of jack, it can align with polished rod, which eradicate the problems caused by offset-wearing of pol- ished rod sealer. It also has the function of shutting down the well and theft proofing.
