摘　　要：河南油田进入开发后期的高含水阶段后,主力油层水淹严重,挖潜增产对象逐渐向物性差、能量低、难开采的非主力油层转移。CO2高压气溶胶酸压技术正是一项融合酸化、压裂于一体,通过CO2汽化膨胀、强力压裂造逢、酸蚀裂缝岩壁,达到增加地层能量,改善储层物性及流体性质的增产技术。文中介绍了CO2高压气溶胶的作用机理和所选区块典型井原油室内试验的适应性。室内试验及现场应用结果均表明,该技术能提高地层原油的渗流能力,增产效果显著,具有广阔的推广应用前景。In later-period of Henan oilfield development, water-cut is high, major reservoirs have been watered-out seriously, production zone shift gradually to non-main layer of poor physical property, low energy and recovery difficulty. CO2 high-pressure aerosol acid fracturing technology is an effective stimulation. It can increase formation energy, improve reservoir physical property and fluid property by CO2 vaporizing expansion, making fracture with strength fracturing and acid etching fracture. The paper introduced the principle of high-pressure aerosol and the adaptability of the typical well crude oil in laboratory testing. The results of laboratory experiment and field application indicate that the technology can increase the filtration ability of the crude oil and have notable stimulation effect and wide application prospects.
