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。
Abstract
On the basis of analyzing the mechanism of CO2 huff-puff,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 huff-puff,especially when used in heavy crude fields by bottom water. CO2 huff-puff technique has been successfully used in QK18 well and gained economic benefits obviously.
