摘要
通过对CO2吞吐采油机理的分析,认为稠油井进行CO2吞吐有利于降低地层渗流阻力,增加驱动能量,从而提高稠油井产量。特别是底水稠油油藏,CO2吞吐开采是一种较合适的方法。QK-18井CO2吞吐采油获得了成功,取得了明显的经济效益。
On the basis of analyzing the mechanism of CO2 huffpuff,the paper deemed it could reduce the resistance force of seepage flow in formation,increase driving pressure and therefore improve the production rate using CO2 huffpuff,especially when used in heavy crude fields by bottom water. CO2 huffpuff technique has been successfully used in QK18 well and gained economic benefits obviously.
