摘要： A drill rod assembly (100, 200, 400, 500) including inner (110, 210, 410, 510) and outer (120, 220, 420, 520) drill rods. The drill rod assembly further including flow passages (140, 240, 440, 540) that are in fluid communication with an annular fluid flow path (160, 260, 460, 560) defined between the inner and outer drill rods. The passages preventing blockage of a drill string fluid flow path when a number of drill rod assemblies are interconnected to form a drill string.
摘要翻译：包括内部（110,210,410,510）和外部（120,220,420,520）钻杆的钻杆组件（100,200,400,500）。所述钻杆组件还包括与限定在所述内钻杆和所述外钻杆之间的环形流体流路（160,260,460,560）流体连通的流动通道（140,240,440,540）。当多个钻杆组件互连以形成钻柱时，通道防止钻柱流体流动路径的堵塞。

摘要： The present disclosure provides a drill drive unit and drill string make up and break up method for use with a dual pipe drill string configuration. The drill drive unit includes telescoping outer and inner drive shafts that are configured to rotate independent of each other. The method involves connecting and disconnecting inner shafts and outer shafts of the dual pipe drill string.

摘要： A continuous flow slurry cleaning method, apparatus and system including a filter portio and a mud re-circulation manifold for receiving partially filtered slurry, containing the slurry and mixing the slurry with liquid ready for use and thereby enabling a continuous, re-circulating flow through the filter portion. The continuous flow slurry cleaning apparatus and system further include a tank for storing and delivering liquid ready to be used by a drilling machine. The continuous flow slurry cleaning method, apparatus and system further includes a mud circulation/agitation system keeping solids in suspension and for mixing additives along with the liquid ready for use and thereby modifying the make-up of the liquid ready for use.
摘要翻译：一种连续流浆清洗方法，装置和系统，包括用于接收部分过滤的浆料的过滤器口和泥浆再循环歧管，其含有浆料并将浆料与液体混合即可使用，从而使得能够连续，再循环流过过滤器部分。连续流浆清洁装置和系统还包括用于储存和输送准备由钻孔机使用的液体的罐。连续流浆清洗方法，装置和系统还包括泥浆循环/搅拌系统，其将固体保持在悬浮液中，并将添加剂与待准备使用的液体一起混合，从而修改准备使用的液体的组成。
