Application of the gas lift valve in liquid discharge technology and its prospects in daqing oilfield
Well Testing(2013)
Abstract
The application of gas lift drainage technology by gas lift valve can achieve well depth on the drainage operation needs within 4500 m, not limited by the well condition, only needing a group of nitrogen, can't only adapt to different liquid production wells and low yield of non self flow well, but also adapted to the liquid in the corrosive medium and sand well, especially suitable for high gas oil ratio well, and inclined well, directional well and complex well conditions, which has simple operation and management, changes the working system of the flexible and other advantages. Combined with gas lift valve discharge technology basic principle and field application to summarize and do the research, a set of technical solution is formed.
