Description
Technical field
The utility model relates to mechanical field, the particularly a kind of wear-resisting spiral drill pipe cladding of chip removal equipment that helps.
Background technology
The efficient drilling technology of deep hole is one of gordian technique of coal-mine gas extraction, and drilling depth is determining the scope and the efficient of gas pumping.Because the condition of coal seam occurrence difference of each department, the complexity difference of coal seam deep well drilling is very big.Weak seam and gas are projecting coal bed to occupy significant proportion in China's minable coal seam, hole in this class coal seam, and especially in the high zone of terrestrial stress, occur easily collapsing hole and bit freezing phenomenon cause the Completion of Drilling Hole rate low, and depth of pore forming is shallow.Weak seam and projecting coal bed in to carry out drilling construction be one of difficult problem of domestic and international drilling technique always.
The present domestic gas drainage mode of creeping into commonly used has light face rod boring, (the general drill bit of this drilling method is bigger than the diameter of drilling rod for wind-force or waterpower chip removal, rely on high pressure draft or current to discharge the space of drilling cuttings between drilling rod and drill hole wall) and the screw-blade rod boring, rely on the chip removal of screw machine power.Light face drilling rod wind-force or waterpower chip removal are not having gas outstanding, and the drilling speed degree is fast in the higher coal seam of the coefficient of hardness of coal, hole quality good, boring is also deep.But at weak seam with gas is projecting coal bed when creeping into, because factors such as terrestrial stress, gas pressure, drilling rod vibrations, the hole of collapsing, part in boring, often occurs and embrace the drilling rod phenomenon, this moment, wind-force or waterpower channel of chip removal stopped up, the lighter's bit freezing, lose brill, lead to serious accident because of frictional heating causes coal and gas combustion when serious.Use the screw-blade rod boring, the screw-blade chip removal needs powerful machinery to move power, occurs inhaling the bar drill phenomenon of boring, break when getting into certain degree of depth easily, and boring length is restricted.
For solving such difficult problem, expert, scholar and field technician are constantly making great efforts research.As license number is 200610111830.5 disclosed a kind of outburst coal seam hole temperature-reducing drilling tool and drilling methods, provide in this patent a kind of on light face drilling rod is got on the bus the novel drilling rod of spiral grooves.This kind drilling rod has played mediation in actual applications because of the blocked main channel of chip removal effect in the hole of collapsing, but because groove has caused the drilling rod basal area to reduce, adds factors such as stress concentration, wearing and tearing, and drilling rod is frangibility more.Patent publication No. is 200910064357.5 to disclose double-power low spiral auger and working method thereof.Provide two kinds of methods to make spiral drill pipe in this patent, a kind of is to become one or more straight line fin and then heating to be reversed into the spiral ridge drilling rod steel pipe rolling, and another kind is with special high rigidity mould ordinary light face drilling rod roller (squeezing) to be pressed into the spiral ridge drilling rod.The spiral drill pipe that these two kinds of methods are made can both rely on low spiral power to dredge main channel of chip removal, increase and creep into length, but its shortcoming is the tooling cost height, and drilling rod formed spiral ridge in surface and drilling rod main body are low with a kind of material hardness, will be worn very soon at drilling process.
In sum, design is a kind of can cladding become the specific equipment of wear-resisting spiral ridge imperative on ordinary light face drilling rod.
