为进一步提高钻井速度,基于现有双驱动加PDC钻头钻井技术之上,配以含砂钻井液可实现冲击钻井技术与切削钻井技术的一种完美结合。既可充分利用现有钻井技术的高泵压、低转速,又可兼顾现有钻井液配方的针对性。无需添置过多钻井设备,节约场地,使用简单,增加钻速。如能合理利用将是一项能大大节约建井周期的钻井技术,同时降低了钻井成本,提高了钻井收益。
In order to further improve the drilling speed, based on the existing double-drive plus PDC bit drilling technology, sand drilling fluid can be used to achieve a perfect combination of percussion drilling technology and cutting drilling technology. Can make full use of existing drilling technology, high pump pressure, low speed, but also take into account the existing drilling fluid formulations. No need to purchase too much drilling equipment, save space, easy to use, increase drilling speed. If it can be reasonably utilized, it will be a drilling technology that can greatly save the drilling period and reduce the drilling cost and increase the drilling benefit.
