Analytical research on design of diamond drill bits with the system theory approach

摘要:

地质钻探工程是个复杂的系统工程，金刚石钻头设计是个复杂的系统。俄罗斯技术科学博士Скоромных В. В.教授等使用系统论方法设计表镶金刚石钻头，以机械钻速为目标函数，以钻头切入岩石深度为切入点，建立了相关的数学模型，编制了程序，进行了计算机模拟，可以比较直观地看到金刚石在孔底的工作情况和钻头破碎岩石的过程，对于深入研究孔底岩石破碎过程机理和判断金刚石钻头设计的合理性及其对钻探技术经济指标的作用，具有一定的实际意义。

Abstract:

Geological drilling engineering is a complicated system engineering and design of diamond bits is a complicated system. Russian Doctor of technical sciences and Professor Skoromnyh V.V. and others have designed surface set diamond drill bits using the system theory approach, where the mechanical penetration rate is taken as the objective function with the cutting depth of the drill bit as a cut-in point to build the mathematical model, and develop the program to perform computer modeling. The modeling results allow the working situation of the diamonds in the bottom hole and rock fragmentation process to be seen more directly, which have some practical significance for in-depth research on the mechanism of rock fragmentation process and assessment of the rationality of the diamond bit design, and their influence on the technical and economical index of drilling.
