Work drilling machine is pumping reverse circulation type. It works are: the role of atmospheric pressure, the circulating fluid from the settling tank through the return ditch along the annular gap flow to the wellbore bottom, because the turntable drive 70 meters drill drilling machine how much money, Rotate the drill drive drilling mud pump suction by the negative pressure in the debris to establish the drill mud suction lumen, then rose to the faucet, the mud pump into the sedimentation tank, circulating fluid continues to flow after precipitation wellbore, so Again and again, the formation of a reverse circulation drilling work. Mud or water 70 meters from the drill pipe into the drilling machine production line, the outflow from the wellhead. Positive circulation drilling machine. Mud or water from the drill pipe sucked out from the wellhead inflows. For the reverse circulation drilling machine. Refers to reverse circulation drilling fluid (mud or water) in the drilling machine cycle ways to say, the drilling machine drill drilling time will have to produce sediment, slag stone, by reverse circulation can take the mud these scum to the ground, and then through the mud after the settler back to drilling. Thus, the continuous cycle, and finally into the hole. Reverse circulation can bring a larger diameter slag. We are here to introduce the use of drilling rigs drilling a prerequisite. First 70 meters drilling machine manufacturer, choose a good location 70 meters hit the wellhead drilling machine, according to the requirements, dug with the same drill diameter, depth and drill roughly the level of Marui, into which the drill bit, the hoist wheel centering round hole dug wells center, place of drilling machines, drilling team when Jackie wells according to geological conditions, determined by water when soil with water or mud fight, must meet when mud mixed with sand and sediment layer, in order to avoid stasis bar. 70 m drilling machine production line _ _ Guangdong 70 m drilling machine provided by Luoyang Prius Prius Drilling Equipment Co., Ltd.
