摘　　要：在石油钻井工程中,钻头喷嘴组合方式的选择对钻进速度有着重要的影响。目前,喷嘴组合的选取都是基于经验得到,因此,对喷嘴组合的优选就显得特别重要。针对不同的地层特性,得到喷嘴的最优组合方式,然后利用计算机编程软件直接得到钻头喷嘴直径的计算结果。试验验证表明,文中的设计方法可满足钻井工程的需要,对指导现场钻井有重要的意义。In the petroleum drilling engineering, the combination mode of bit nozzle has been playing an important role in the drilling speed. At present, the bit nozzle selection is mainly based on experience. So, the optimization of nozzle combination seems especially important. This paper obtains it according to different formation characteristic. Then, the calculation results of bit nozzle diameter can be directly obtained by the computer programming software. The experiment shows the design method in this study satisfies drilling engineering needs and has a important meaning for field of drilling.
