| Abstract: | Screw drill is a mature technology which is widely used in oil and coalfield geological drilling due to its high ROP and obvious economic benefit, but it is still at the experimental stage in the geothermal well drilling construction.The paper elaborates a series of issues of the equipment, drilling technology and the benefit comparison, affirms the drilling efficiency and economic benefits of screw drill in the geothermal drilling and puts forward some problems to be solved in future prac-tice. |
