摘要:
CO2驱被认为是提高采收率最有效的方法之一。制约其应用的主要因素就是气源问题,以及腐蚀、安全和环境影响等。层内自生气吞吐技术是近年来发展起来的一种新技术,该技术是在地层条件下发生化学反应产生大量气体并伴随释放出的大量热量,可以增加油层能量,降低原油粘度和解除近井地带堵塞的作用,从而提高单井产能。研制了一种新型的自生气体系,NS-1。实验结果表明:该体系具有生气量大、放热量大的特点; 吞吐效果随着岩心剩余油饱和度的增加而越好。该技术在W5稠油油藏应用3口井,均取得了较好的增油降水效果,证明该技术是一项较好的提高采收率技术。
Abstract:
Carbon dioxide flooding is considered one of the most effective technology for improving oil recovery.One of the main factors restraining wide application of this technology is its dependence on natural CO2 sources,which introduces complicating factors such as the corrosion of well and field equipment,safety and environmental problems.The in-situ gas generation technology is based on an exothermic chemical reaction,which releases high heat and large volume gas,to remove the organic and inorganic deposition from around the wellbore and reduce oil viscosity.In the lab,we developed a new in-situ gas generation formula,NS-1.Lab results indicate that the new formula has characters of large gas volume and high heat,and high enhanced oil recoveries were associated with high initial waterflood residual oil saturations.The technology was applied in three wells of W5 heavy oil reservoir.The field results suggest that because of promising results obtained from the three wells,the technology is a better EOR technology.
