工业界越来越重视钻井难度、速度和持续时间，由此也带来了钻头过早失效的挑战，尤其是在钻穿强度变化不定的岩层过渡带时。为了解决这个问题，一些新的策略应运而生，例如使用以恒定钻速（ROP）运行的自动钻机。本研究开发了一种方法，用于分析钻穿岩层过渡带对钻头切削结构的影响，并利用详细的钻井模型构建理想的钻井策略，以减轻切削刃的过载力。
本文采用基于物理的钻井模拟环境，研究了钻穿地层过渡带对多晶金刚石复合片（PDC）切削结构的影响。该环境既可用于模拟单个钻头，也可用于模拟钻头与钻具组件的组合。
该环境允许使用给定的PDC钻头设计钻探各种岩层或岩性，并生成一系列表征钻头性能的输出结果。首先，必须设置岩性、钻井路径以及相应的深度。
The industry is placing increased importance on drilling harder, faster, and longer, giving rise to the challenge of premature bit failure caused by drilling through transitions of varying rock strength. To address this issue, new strategies have emerged, such as using automatic drillers operating with a constant rate of penetration (ROP). In this study, a method was developed to analyze the effects of drilling through transitions on bit-cutting structures and construct an ideal drilling strategy to mitigate the forces overloading cutters using a detailed drilling model.
A physics-based drilling-simulation environment was used to study the effects of drilling through formation transitions on polycrystalline diamond compact (PDC) cutting structures. The environment can be used to model only a drill bit or a drill bit attached to a drilling assembly.
The environment allows a given PDC drill-bit design to be run through various rock formations or lithologies and can generate a set of outputs that characterize bit performance. First, rock lithologies and a drilling path must be set along with corresponding depths.
