通过ZJD油藏注CO2驱替提高采收率实例,使用室内实验的方法对开发初期注CO2驱替中没有达到混相驱的油藏,经过注气提压达到CO2混相的过程,对比不同时期注CO2气采收效果,验证油藏是否还有增产潜力,并评价其效果,为ZJD油藏合理开采方式的选择提供依据,所得实验结果也为同类油藏开发提供技术借鉴。 Through the ZJD reservoir injection of carbon dioxide displacement for enhanced oil recovery example, the use of laboratory experiments in the early development of CO2 flooding did not reach the miscible flooding reservoirs, after gas injection to achieve CO2 mixed phase process, compared to different periods of injection CO2 gas recovery results to verify whether the reservoir potential increase yield and evaluate the effect of ZJD reservoirs to provide a reasonable choice of mining methods to provide the basis for the results obtained for the development of similar reservoirs to provide technical reference.
