摘　　要：目前,海上油气田开发通常采用自喷生产管柱或电潜泵生产管柱,已探明的部分特殊油气田具有地层压力高、气油比高以及压力衰竭快的特点,后期需采用电潜泵人工举升开采,常规生产管柱无法满足此类油气田安全经济高效开发要求。该文提出一种兼备自喷生产和电潜泵人工举升两种生产方式的新型复合生产管柱,并应用于南海西部涠洲X油田,实现了该油田安全经济高效开发,为海上类似特殊油气田开发提供参考。At present,the development of offshore oil and gas fields usually adopts the flowing production tubing string or electric submersible pump production tubing string.Some of proved special oil and gas fields have the characteristics of high formation pressure,high gas-oil ratio and rapid pressure depletion,so they need to be explored by manual electric submersible pump lifting in the later stage,and the conventional production tubing string cannot meet the requirements of the safe,economic and efficient development of such oil and gas fields.This paper puts forward a new composite production tubing string with the two production modes of flowing production and manual electric submersible pump lifting,and applies it to the Weizhou X oilfield in the western South China Sea,which realizes the safe,economic and efficient development of the oilfield,and provides a reference for the development of similar special offshore oil and gas fields.
