摘要
CO2驱油,作为三次采油、提高原油采收率的一种新工艺技术,已取得了一定的进展。其中,CO2注入管柱是确保CO2驱油成功关键因素。为此,开展了CO2注入配套工艺管柱调研和室内研究。并在草舍油田进行了现场CO2注入试验。试验表明,该管柱可以满足深井注入CO2的要求,施工取得了成功。
CO2 flooding,as a new technology for tertiary oil recovery and EOR,has made some progress.CO2 injection string is a key factor in successful CO2flooding.Therefore,surveys and indoor researches were carried out on the matching technical string of CO2injection,and field test of CO2injection was carried out in Caoshe oilfield.The test made success and the results indicated that the string could meet the requirement of CO2injection for deep wells.
