摘要

如何有效开采疏松砂岩气藏一直是世界性的难题。针对涩北气田第四系疏松砂岩气藏开发中存在出砂严重、治砂难度大,管外封窜不严、治水难度大等难题,青海油田公司经过多年的探索试验和攻关研究,在多项工艺技术上得到突破,形成了适合涩北气田疏松砂岩气藏的出砂监测技术、防砂工艺技术、冲砂工艺技术、分层开采技术和排水采气工艺技术等特色开发技术。通过采气工艺技术的现场试验和推广应用,表明这些工艺技术是进行疏松砂岩气藏开发的有效方法,并为涩北气田的产能建设做出了重要贡献。

Abstract

How to raise the exploiting efficiency for loose sand reservoirs has been an emphasis for natural gas enterprises world\|wide. In course of the exploitation in Sebei gas field comprising Quaternary loose sand reservoirs, there existed problems such as severe sanding, hard sand\|controlling, bypass channeling, and hard water-controlling. New techniques have been developed to adapt the exploitation of loose sand reservoirs in Sebei gas field, including sand-flux monitoring, sand controlling, sand flushing, zonal withdrawal, and production while water pumping. Applications of these new techniques for several years in Sebei gas field suggest the efficiency in exploitation of loose sand reservoirs.
