Abstract
The invention relates to the field of drilling equipment, in particular to a jamming-prevention drill pipe structure. The jamming-prevention drill pipe structure aims at achieving the technical purpose of effectively preventing drilling cuttings from jamming a drill bit. The jamming-prevention drill pipe structure comprises a drill pipe, a sealing gas bag is connected to the periphery of the drill pipe in a sleeving mode, a high-pressure inflating pipe is arranged on the drill pipe, the sealing gas bag is used for sealing a drill hole into a sealed cavity, and the sealed cavity is filled with high-pressure gas through the high-pressure inflating pipe. When the high-pressure gas in the sealed cavity reaches certain pressure, a pressure relief seam is made to appear in the sealed cavity by releasing the gas in the sealed gas cavity, and a large quantity of drilling cuttings can be discharged out of the drill hole along with the flowing-out high pressure gas when the high-pressure gas is rapidly discharged out of the seam. Certainly, if one-time cutting discharging is not sufficient, a second time and even more times of cutting discharging operation can be further conducted immediately, high convenience and effectiveness are achieved, and good market popularization prospects are also achieved. The jamming-prevention drill pipe structure is especially suitable for being applied to working places where efficient drilling is needed.
Description
Technical field
The present invention relates to rig field, especially a kind of preventing sticking jackrod structure.
Background technology
In the process of boring, along with drilling depth increases, the windage of drilling rod and hole wall increases, deficiency in draught in causing hole, thus drilling cuttings is got rid of not thorough, the drilling cuttings produced in hole is piled up gradually in hole, further increase deslagging resistance again, until block in hole, block drilling cuttings passing away completely, bit freezing occurs.
The wider way of current domestic use uses pressure wind or water by drilling cuttings in aperture progressively cleaning eye, but when using drilling cuttings in the method cleaning eye, consuming time longer, particularly during deep hole bit freezing, the time high several times that the time processing a lock of tool drilling holes than normal construction one.How fast drilling cuttings and the efficiency improving Treating Jammed Bit Accident in evacuation aperture, become urgent problem in the gun drilling construction of colliery.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of preventing sticking jackrod structure effectively preventing drilling cuttings from blocking drill bit.
The technical solution adopted for the present invention to solve the technical problems is: preventing sticking jackrod structure, comprise drilling rod, the periphery of described drilling rod is socketed with pressure bladder, described drilling rod is provided with high-pressure aerated pipe, borehole sealing is closed chamber by described pressure bladder, and high-pressure aerated pipe is full of gases at high pressure by described closed chamber.
Further, described high-pressure aerated pipe is arranged in drilling rod, and the gases at high pressure in high-pressure aerated pipe are discharged by the exhaust opening be arranged on drilling rod.
Further, described exhaust opening is arranged at the drill bit one end near drilling rod.
Further, described pressure bladder is rubber seal air bag.
Further, described rubber seal air bag is provided with charging valve.
The invention has the beneficial effects as follows: when reality uses, first drill bit is extend in boring normally, carry out normal bore operation.When needing to clear up the drilling cuttings in boring, by being closed chamber to pressure bladder inflation by borehole sealing, be then full of gases at high pressure by high-pressure aerated pipe by described closed chamber.After the gases at high pressure of closed chamber reach certain pressure, by the gas in releasing pressure bladder to the gap allowing above-mentioned closed chamber occur pressure release, and during along with gases at high pressure discharging from gap rapidly, a large amount of drilling cuttings can in company with the gases at high pressure flowed out from discharge in boring.Certainly, if a chip removal is abundant not, the even more chip removal operation of second time can also be carried out immediately, very easily and effectively, also have marketing prospect.The present invention is particularly useful for the workplace application needing high efficiency to hole.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention when applying.
Be labeled as in figure: hole wall 1, boring 11, drilling rod 2, pressure bladder 21, drilling rod link 22, drilling rod rod end 23, drill bit 24, high-pressure aerated pipe 3, drilling cuttings 4.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described.
Preventing sticking jackrod structure as shown in Figure 1, comprise drilling rod 2, the periphery of described drilling rod 2 is socketed with pressure bladder 21, and described drilling rod 2 is provided with high-pressure aerated pipe 3, boring 11 is sealed into closed chamber by described pressure bladder 21, and high-pressure aerated pipe 3 is full of gases at high pressure by described closed chamber.
The way of the removing drilling cuttings 4 that domestic use is wider be use pressure wind or water by hole 11 aperture progressively clear up drilling cuttings 4 in boring 11, but when using drilling cuttings 4 in the method cleaning eye, consuming time longer, particularly during deep hole bit freezing, the time high several times that the time processing a lock of tool drilling holes than normal construction one.The present invention run into the drilling rod rod end 23 of drilling cuttings 4 by drilling rod 2 embrace namely there is bit freezing situation time, first only need pressure bladder 21 be set in the boring 11 of hole wall 1, adjust the position of drilling rod link 22, allow pressure bladder 21 be positioned at boring 11 as far as possible, then pressure bladder 21 is inflated, then boring 11 blocked completely thus in boring 11, form the closed chamber closed; Ensuing, gases at high pressure are full of by described closed chamber by high-pressure aerated pipe 3, after the gases at high pressure in closed chamber acquire a certain degree, pressure bladder 21 is exitted, now, there is the gap of pressure release in just now also completely airtight closed chamber, along with gases at high pressure are by the outflow in gap, the drilling cuttings 4 of a large amount of especially powderies is also taken out of boring 11 thereupon, thus achieve conveniently, efficiently drilling cuttings 4 clear up.Certainly, even if once clear up insufficient, also can clear up by the drilling cuttings 4 that carries out that comes again of the method for the then first step.
Certainly, generally in order to allow more compact structure of the present invention and durable, described high-pressure aerated pipe 3 can be selected to be arranged in drilling rod 2, and the gases at high pressure in high-pressure aerated pipe 3 are discharged by the exhaust opening 31 be arranged on drilling rod 2.As shown in Figure 1, the gases at high pressure be filled with can be realized by high-pressure aerated pipe 3 and exhaust opening 31, so also allow drilling rod rod end 23 that high-pressure aerated pipe 3 can well be protected to be blocked by drilling cuttings 4.Certainly, in order to allow, described gases at high pressure are as much as possible to be distributed in boring 11, thus can take more drilling cuttings 4 out of, as shown in Figure 1, can select described exhaust opening 31 to be arranged at drill bit 24 one end near drilling rod 2.
General, under well sealing up the prerequisite of boring 11 at guarantee pressure bladder 21, reduce the cost of pressure bladder 21, preferred described pressure bladder 21 is rubber seal air bag.For described rubber seal air bag, charging valve 211 can be set on rubber seal air bag, be convenient to inflation and exhaust.
