井筒压力控制地层隔离阀完井工艺技术应用

南海东部某深水油田采用天然能量衰竭式开发，为了最大限度地保护储层，延长油井寿命，提高采收率，针对其油藏特点、基本井况及作业需求，提出了一种使用井筒压力控制地层隔离阀进行完井的完井工艺，并在现场成功应用，取得了良好的储层保护效果。该工艺技术的成功应用对于深水油田开发具有积极意义。

A deep-water oilfield in the eastern South China Sea is developed by natural energy depletion. In order to protect the reservoir to the maximum extent, extend the life of the oil well and increase the recovery rate, according to the characteristics of the reservoir, the basic well conditions and the operation requirements, a well completion technology using the wellbore pressure control formation isolation valve is proposed. This technology has been successfully applied on site and achieved good reservoir protection effects, which has a positive significance for the development of deepwater oil fields.
