靖边气田延长稳产期的地面集输工艺技术

靖边气田经过十多年的开发建设,气藏资源和地层能量迅速衰竭,部分气井井口流动压力已不能满足气田正常生产需求。为了保证靖边气田55亿m3/a的生产规模,实现气田长期稳定、高效开发,在原有常温地面集输工艺的基础上,又研究试验了上、下古气藏合采地面集输工艺及整体增压地面集输工艺。文章介绍了这三种延长稳产期的地面集输工艺技术。

Surface Gathering Technology for Prolonging Period of Stabilized Production in Jingbian Gas Field

After more than a decade of exploitation and construction in Jingbian Gas Field, the gas reservoir resource and formation energy have exhausted rapidly, and the flowing pressures at partial gas wellheads have not been able to meet the requirement for normal production.To ensure Jingbian Gas Field to realize long-term stable and high effective production with the capability of 55×108 m3/a, the surface gathering and transportation technology including the commingled production of Upper and Lower Palaeozoic gas reservoir and the integral supercharging was studied and experimented on the basis of the original surface gathering and transportation technology at normal temperature.These three surface gathering and transportation processes for prolonging period of stable production are introduced in this paper.
