摘要
以喷射钻井为例,对不同入口形状的喷嘴的射流水力参数进行对比,在同一喷砂介质和同一气流压力下进行喷射实验,对比4种喷嘴的使用寿命,得出碳化硼喷嘴是最理想的井下喷射材料,同一种材料的喷嘴入口形状为流线性和等变速的喷射效果最佳。
Taking the nozzles to apply for drilling field as an example, the different shapes of nozzles used in the same field were compared. Realnt showed that boron carbide is the ideal material for the nozzles used in the drilling field. Even though the same material nozzles, the different entrances with llne or speed has more perfect than the normal shape.
