Prevention of Bit-Balling by Electro-Osmosis

将研究使用电渗来减少钻头 成球钻井 钻头成球是一个主要问题， 在软岩中钻孔，由于软岩或粘土是粘性的， 堵塞钻头，降低机械钻速。 现在意味着 通过使用油基泥浆或其他泥浆来减少钻头泥包， 环境越来越不令人满意。 电- 渗透作用，即在钻头上施加电流， 粘土界面，释放水，并降低了 钻屑粘在钻头上。

The use of electro-osmosis will be investigated to reduce bit balling oil well drilling. Bit balling is a major problem when drilling in soft rocks, since the soft rocks or clay are sticky, clog the bit, and reduce the rate of penetration. Present means of reducing bit balling, by the use of oil-based or other muds, are becoming increasingly environmental unsatisfactory. Electro- osmosis, the application of an electrical current across the bit- clay interface, liberates water and reduces the tendency of the drilled cuttings to stick to the bit.
