Drilling for oil and gas is a costly activity (around £1M/day). The drills are complex robotic machines, capable of autonomously controlling their steering using attitude sensors while working in some of the most extreme and challenging environments (up to 3000psi - 200 atmospheres - and 120C, and operating in drilling "mud" - heavy liquid designed to prevent well blowouts). Any enhancement to the performance of the drill has potentially large economic benefits, and that is the objective of this project. Magna Parva will investigate the feasibility of enhancing the performance of these drills (especially in hard rock such as granite or marble) by applying high frequency vibrations ahead of the cutting teeth. Such vibrations have two potential effects: (a) generating microcracks in the rock and (b) reducing friction. This latter is particularly interesting, because it may assist the autonomous steering of the robotic drill, so we will make "wet" tribometer measurements under drilling mud.

钻探石油和天然气是一项昂贵的活动（每天约100万英镑）。这些钻机是复杂的机器人机器，能够在一些最极端和最具挑战性的环境下（高达3000psi - 200大气压- 120摄氏度，并在钻井“泥浆”中操作-旨在防止井喷的重液体）工作时，使用姿态传感器自主控制其转向。钻头性能的任何提高都可能带来巨大的经济效益，这也是本项目的目标。麦格纳帕尔瓦将研究通过在切削齿前施加高频振动来提高这些钻头（特别是在花岗岩或大理石等坚硬岩石中）性能的可行性。这种振动有两个潜在的影响：(a)在岩石中产生微裂缝(b)减少摩擦。后者特别有趣，因为它可能有助于机器人钻机的自主转向，因此我们将在钻井泥浆下进行“湿”摩擦计测量。
