| Abstract: | Yulin gas field from 2003 to and downhole choking applications technology,by the end of June,2012,has been applied for downhole choking 47 well,there are 12 tones well downhole throttling device failure.Based on the downhole throttling technology in Yulin gas field based on the analysis of current situation,through a thorough search of downhole choke running and throwing process problems,from two aspects of process and structure optimization for production allocation,downhole throttle technology provides effective means,and from structure to improve the working life of the downhole throttle. |
