一、泥浆钻进法所有需用冲洗介质从孔底排除切屑的钻进方法都属于冲洗钻进技术。冲洗介质可为清水和固体的混合物、气体、气体与液体的混合物或含气液体。岩石可用回转、冲击或冲击回转法来破碎,其驱动可以在井上,也可在井下进行。钻屑可通过钻杆和孔壁之间的环状间隙上返。或者通过钻杆内部上返。 First, the mud drilling method All need to flush the media from the bottom of the hole to exclude chips drilling methods belong to the flushing drilling technology. The flushing medium can be a mixture of clean water and solids, a gas, a mixture of gas and liquid, or a gas-containing liquid. The rock can be crushed using swivel, impact or impact-turning methods and can be driven either uphole or downhole. Cuttings can return through the annular gap between the drill pipe and the hole wall. Or go back up through the drill pipe.
