靖安油田注气试验地面工艺技术

Surface Technological Process for Pilot Gas Injection in Jing’an Oilfield

靖安油田是长庆石油勘探局近年重点开发的低渗透油田，为有效利用气井资源，提高油田采收率，提高油田开发经济效益，长庆油田在对靖安油田实际情况进行分析的基础上，吸取长庆低渗透油田和长庆气田的设计经验，利用该地区油气藏上下迭合的特点，提出一种新的注气地面工艺，并在多方论证的基础上在试验站内采用了热载体加热系统，经实际应用，取得了较好的效果。

Jing’an oilfield of low permeability is the key project of Changqing Petroleum Exploration Bureau in recent years. Based on the experience for low permeability oil zone and gas reservoir development, a new type of surface technologies for gas injection is put forward in light of the interbeding reservoir characteristics of the field as a way to increase recovery, improve economics and utilize oil resource in a more efficient way. Thermal carrier heating system is used in pilot stations and has generated good results.
