摘　　要：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。Based on the example of improving recovery ratio by C02 injection displacement in ZJD reservoir, we adopted indoor experimental methods in reservoir, which didn＇ t achieve miscible flooding effects at the initial stage of development. After pressure improvement by gas injection, the reservoir had C02 miscible flooding effects. Comparing with gas recovery effects of C02 injection in different period, whether the reservoir has yield increasing potential can be approved, and its effects can be evaluated. The resuits can provide reasonable production methods for ZJD oilfield and technical references for similar reservoir as well.
