摘要: 文介绍了采用不等径喷嘴组合时,喷射钻头水力侧向力的试验研究方法和主要认识。研究表明,当采用不等径三喷嘴、组合双喷嘴和单侧喷嘴时,钻头上水力侧向力的大小主要与排量、泥浆比重和喷嘴的当量直径有关。

Abstract: This paper presents a method for the hydraulic force experiment of a jet bit. The result obtained shows that with three unequal-diameter nozzles, two nozzles or single nozzle being used, the value of the hydraulic side force on the bit is mainly dependent on the flow rate, the mud weight and the equivalent diameter of nozzles.
