摘　　要：为满足独山子炼油厂的原油需求,克拉玛依至独山子管道(克独管道)拟将输量从 300×104t／a(原设计输量)提高到340×104t／a。提出了启用克独三管提高输量的设想。为解决不等管径双管并联交替输送工艺产生混油的问题,从理论上进行了分析和计算,并对克独三管输送管道进行了工艺和设备的改造,最终实现了不等管径双管并联交替输油。Kelamayi-Dushanzi Oil Pipeline,with the transportation capacity of 300×104 t/yr,is consisted of three pipelines laid parallelly that the diameter of main pipeline is DN 150,the reduced pipe in DN 250/200/150 (build in 1962) and the pipe in DN 350 (build in 1991), the later pipe at present transport alternately Kelamayi blended oil and Lushi blended oil and the other two pipelines are in shutdown condition. To meet the needs of 300×104 t/yr oil to Dushanzi Oil Refinery,the reduced pipe and DN 350 pipe are decided to put into operation to transport oil with combinational transportation process,that is alternated transportation technology. To avoid the oil blending, the theoretical analysis and hydraulic calculation are made. By means of technical reform in process flow and pumping equipments, the combinational transportation process is realized.
