数值方法在钻进模拟试验中的应用

Application of Numerical Value Method in Drilling Analogue Test

摘要:

用不同规格的硬质合金取心钻头在同一种岩石中进行钻进模拟试验，通过对试验数据的整理，利用数值分析方法，建立在最优钻进规程下的钻头直径与机械钻速之间的相关方程。

Abstract:

Carbide core bits of different sizes are used to perform drilling analogue test in the some rocks,bysorting of test data and using of numerical valule analysis method,the correlatioln equqtion between bit diameterand penetration rate under teh iptimized drilling is set up.
