摘　　要：针对准噶尔盆地排66块火成岩非均质性严重、原油黏度大造成的开发方式不确定的问题,运用数值模型方法,结合油藏实际动态特征,通过参数敏感性分析,确定了原油黏度和储层渗透性对此类油藏采收率影响较大,并提出以地层原油流度作为区块冷采和热采两种不同开发方式的界限,得出了排66块原油流度和热采净增油提高值的关系曲线,当原油流度大于0.163 m D/m Pa·s时,采用冷采开发,否则采用热采开发。根据研究,在排66块东部部署5口评价井,均采用冷采开发,并取得较好开发效果。Because of serious heterogeneity and high crude oil viscosity, development mode of Junggar Basin＇s Pai66 igneous reservoir is uncertain. Using numerical simulation method and combining with the actual dynamic characteristics of the reservoir, the crude oil viscosity and reservoir permeability are the main factors which affect recovery after the parameter sensitivity analysis. Formation oil mobility is proposed as a screening criteria of cold recovery or heat recovery. At the same time, the relation chart of the formation oil mobility and net oil increased value by thermal recovery is sketched. When the oil mobility is greater than 0.163mD/mPa·s, cold recovery is the better choice, otherwise heat recovery is more suitable. At last, according to the research results, 5 evaluation wells are deployed in the eastern part of the Pai66, which are developed by cold recovery and have achieved good results.
