摘要
介绍了CDG驱油机理、配方组成 ,并对影响CDG的性能因素进行了室内试验。根据濮城油田高温、高矿化度的特征 ,筛选了适合濮城油田的CDG驱油剂配方 ,根据筛选配方 ,对CDG的性能进行了室内评价和模拟驱油试验。试验证明 ,所选CDG可以明显提高波及系数和洗油效率 ,最终提高油藏采收率。
The papers introduce CDG oil displacement theory,CDG formulation,is tested acting on CDG funetion element,by Pucheng oilfield high temperture high salinity feature,elected suit for Pucheng Oilfield's CDG formulation,and evaluation CDG funetion,on the election formulation,tsted simulation in lab,by testiny prived that CDG can raise sweep efficiency,and can raise oil efficiency,can improve reservoirs recovery efficiency.
