Description
Technical Field
The invention belongs to the technical field of drilling, and particularly relates to a spiral self-righting type drill pipe fisher.
Background
At present, geological drilling refers to a geological engineering which utilizes certain drilling mechanical equipment and processes to obtain rock cores below the earth surface and makes reliable evaluation on geological and mineral resource parameters. In-hole accidents occur in the drill hole due to natural reasons or improper design, management, construction and operation, and the phenomena of normal drilling interruption caused by falling objects, drill rod breakage, drill tool tripping, drill tool clamping and burying, drill bit burning and the like occur in the drill hole. Particularly, the breaking treatment of the drill rod is very difficult, and a large amount of manpower and material resources are consumed.
The existing method for processing the broken drill rod is to salvage the broken drill rod one by adopting a male cone, but the drill rod is very difficult to salvage under the condition that the condition in a hole is complex, the dropped or broken drill rod is tightly attached to the wall of the hole, particularly a horizontal hole and an inclined hole, and the dropped or broken drill rod is tightly contacted with the wall of the hole at the lower side.
In order to solve the problem that the drilling condition is complex, particularly the fishing problem that a horizontal hole and an inclined hole break a drill rod, the spiral self-righting type drill rod fisher is provided.
Through the above analysis, the problems and defects of the prior art are as follows:
the existing fishing mode of the broken drill rod is complex for the situation in the hole, the dropped or broken drill rod is tightly attached to the hole wall, particularly a horizontal hole and an inclined hole, and the dropped or broken drill rod is very difficult to fish under the situation that the dropped or broken drill rod is in close contact with the hole wall at the lower side.
The difficulty in solving the above problems and defects is: traditional salvage and directly adopt drilling rod lug connection male cone or female cone to get into drilling and salvage, because the drilling rod that drops or absolutely hugs closely and leans on the drilling pore wall, male cone or female cone can not be quick with the quick link together of drilling rod joint, under most of the circumstances, male cone can stagger with the drilling rod that drops, leads to the male cone at the continuous friction pore wall in the cracked position of drilling rod, makes the drilling diameter of here enlarge, and salvage work is more difficult. For horizontal holes and inclined holes, the probability of quickly connecting a salvaging male cone or female cone with a broken drill rod joint is very low, and the drill rod salvaging is very difficult. The possibility of a waste hole is very high.
The significance of solving the problems and the defects is as follows: the probability that the drilling rod accident that drops is handled to great increase reduces because of the drilling rod probability that the accident that drops is useless hole, the time of the accident is handled in effectual reduction to the going on of effectual assurance reconnaissance work provides effectual probing data in time, has avoided because of the drilling rod accident that drops and the loss that the useless hole caused.
Disclosure of Invention
Aiming at the problems in the prior art, the invention provides a spiral self-righting type drill pipe fisher.
The invention is realized in this way, a spiral self-centralizing drill pipe fisher comprises: the male cone, the spiral steel claw fixing device and the spiral steel claw are arranged on the outer wall of the steel pipe;
the bottom of the male cone is provided with a turnbuckle in the same direction as the male cone, and the spiral steel claw is sleeved on the outer side of the male cone;
spiral steel claw fixing device sets up in the public awl upper end outside, public awl and spiral steel claw link together through turnbuckle and spiral steel claw fixing device.
Further, the male cone upper end is provided with the screw thread mouth, screw thread mouth upper end is connected with the connector of salvaging the drilling rod.
Further, the spiral direction of the male cone is consistent with the direction of the spiral steel claw.
Furthermore, the inner side of the spiral steel claw is provided with an edge angle, and the bottommost part of the spiral steel claw is flat and is provided with an outer edge angle.
Further, the diameter of the upper end of the spiral steel claw is the same as that of the fishing drill rod, the diameter of the lower end of the spiral steel claw is larger than that of the upper end of the spiral steel claw, and the diameter of the lower end of the spiral steel claw is the same as that of a drilled hole.
Another object of the present invention is to provide a method for controlling a spiral self-righting type drill pipe fisher, which includes:
connecting a threaded port at the upper end of the male cone with a fishing drill rod, and transmitting power generated by a drilling machine to the male cone through the fishing drill rod;
the male cone and the spiral steel claw fixing device drive the spiral steel claw to rotate, and the drill rod which is poured to any direction of the hole wall can be grasped during rotation, and the dropped or broken drill rod is centered by utilizing the gradually reduced inner diameter;
after the spiral steel claw centralizes the drill rod, the male cone is aligned to the dropped or broken drill rod, the inner side of the spiral steel claw is provided with a cutting edge angle, the cutting edge angle has a cutting effect on the dropped slag occasionally appearing in the drill hole, the rising resistance is reduced, and the function of salvaging the drill rod is realized.
By combining all the technical schemes, the invention has the advantages and positive effects that: the drill rod falling or falling off in the drill hole and tightly attached to the hole wall is quickly and effectively salvaged, and particularly the drill rod falling or falling off in the horizontal hole or the inclined hole and tightly attached to the lower side hole wall is salvaged.
The screw tap and the spiral steel claw are connected together by the screw thread and the spiral steel claw fixing device, so that the risk that the spiral steel claw falls off in the process of salvaging the drill rod is effectively reduced.
The inner side of the spiral steel claw is provided with the cutting edge, so that the spiral steel claw can conveniently fall into a drill hole, the resistance when the drill rod is lifted is reduced, and the bottommost part of the spiral steel claw is flat and provided with the outer cutting edge, so that the spiral steel claw can efficiently grab and centralize the dropped or broken drill rod.
The invention is suitable for inclined holes and horizontal holes, and the situation that the drill rod falls or breaks down in the hole and is not centered in the hole.
The directions of the screw tap and the screw thread of the spiral steel claw can be selected according to requirements, and can be clockwise or anticlockwise.
