柱塞气举天然气井用在线监测系统设计

根据气井的生产需求,结合柱塞气举工艺的特点和技术现状,提出一种可进行在线监测的柱塞排液采气系统的设计方案.该系统在柱塞运行期间处于封闭状态,井下监测、排液采气和数据传输之间互不影响,具有结构紧凑、作业效率高、安全性好、关井停产次数少等优点.该技术的应用可在一定程度上取代传统的电缆测井方式,为今后柱塞气举的自动化生产与管理提供了重要的技术保障.

Design of Plunger Lift System with On-line Monitoring for Gas Well Deliquification

In terms of current situation of plunger lift tech.and the field demand on the deliquification of gas wells,this paper put forward an improved solution to the system with on-line monitoring.During operation of system,downhole logging and data transmission have no side effect on the deliquification of gas wells.Instead of the traditional wire-line logging,the new system works in the closed environment with the advantages of compact mechanical structure,high service efficiency,good safety and less non-productive time.Via on-line monitoring tech.the new system pro-vide a significant basis for automated gas production and regulation of plunger lift in the future.
