钻井柴油机二级涡轮增压系统性能分析
Performance of Drilling Diesel Dual-stage Turbocharger

油气钻井工程中钻井柴油机燃油消耗占钻井成本30%以上，尾气是主要污染源。为了积极响应国家节能减排，降低钻井柴油机燃油成本，对钻井柴油机进行二级涡轮增压改造。以济柴190系列柴油机真实尺寸和实验数据为基准，建立了柴油机二级涡轮增压器整体模型，对比分析、确定二级涡轮增压器的布置方案。通过对柴油机整机性能进行模拟、分析结果表明：改进后的柴油钻机二级涡轮增压系统与原机型相比动力性能、加速性能、排放性能、燃油经济性、涡轮增压器运行效率均有显著改善。
The fuel consumption fee of drilling diesel is more than 30% of the cost in drilling engineering, diesel emission has been primary pollution source. In this paper, taking the real structure data and the experiment data of the 190 series diesel engine from Jinan diesel manufacturer to build a Dual-Stage turbocharger diesel model, the arrangement of two stage turbocharger was determined through the comparison and analysis. The results showed that the dynamic performance and acceleration performance, emission performance, fuel economy and efficiency of turbocharger were remarkably improved comparing with the origin engine
