Abstract
A construction tube comprises a tube, and an upper connector and a lower connector which are respectively connected on both ends. The upper connector and the lower connector adopt screw thread with 5.08mm of screw pitch, 1:6 of conicity and 2.98mm of tooth height. The construction tube can replace a drill rod for minor repair; the price is only 2/7 of that of the drill rod with same length, the weight is only 60% of that of the drill rod with same length; the tube can be used by the equipment less than 40t, the tensile strength reaches 850KN; the tube has high safety factors and long longevity, wherein the service life is 10 times of that of heavy wall tubing of same grade steel; the working surface of the hydraulic tong moves to the upper and the lower connectors when making up and breaking out, the teeth of the big hydraulic tong will not hurt the oil conduit tube, which effectively protects the main body of the tube and prolongs the service life of the tube; and the tube can be repaired because the connector can execute screw thread repair after worn out, and the tube can be widely used in workover treatment of oil extraction.
Description
One, technical field
The utility model relates to the operation tubing that uses in the oil well repairing operation process, particularly a kind of job execution pipe
Two, background technology
At present, often use oil pipe to carry out operation operations such as some simple back-off salvagings in the light maintenance operation process, the general employing is that 27/8 left-hand thread heavy wall tubing carries out more, but this oil pipe exists following shortcoming or deficiency:
(1), easily thread gluing.Frequently go up shackle, the easy thread gluing of the screw buckle of oil pipe and box cupling.
(2), can not repair.The external upset tubing thread thread gluing generally can not be repaired after damaging.
(3), application life is short.On the one hand, use shackle on the hydraulic tongs for a long time, be subjected to clamping the tooth injury on the oil pipe body, the body lost of life; On the other hand, thread gluing phenomenon also causes the tubing string lost of life.
(4), antitorque, tensile strength is low.The box cupling screw thread is a tubing round thread, and bonding strength is lower.
(5), kit and joint are universal poor.General workover tool is the drill rod thread button, if will use them, necessary processing transformation joint brings unnecessary trouble to construction.
Three, summary of the invention:
The purpose of this utility model provides a kind of improved shortcoming or deficiency that exists in the above-mentioned prior art that both overcome effectively, the job execution pipe that carries out well workover again effectively smoothly.
Job execution pipe described in the utility model comprises top connection and lower contact that body and two ends thereof connect respectively.It is 5.08mm that pitch is adopted in described top connection and lower contact, tapering 1: 6, the screw thread of tooth depth 2.98mm.
Wherein, described top connection is a box, and lower contact is a pin thread.
The utility model has following advantage or beneficial effect compared with prior art:
1, can substitute drilling rod and carry out the light maintenance job execution;
2, low price, only, in light weight for waiting 2/7 of long drill pipe price, be to wait about 60% of long drill pipe weight;
3, can use with interior equipment for 40 tons, the intensity height destroys tensile strength and reaches 850Kn;
4, safety factor height, the life-span is long, is with more than 10 times of grade of steel heavy wall tubing application life;
The hydraulic tongs work plane moves to joint area up and down when 5, going up shackle, and hydraulic tongs pincers tooth does not injure the oil pipe body, has effectively protected the oil pipe body, prolongs body application life;
6, can repair, can carry out the screw thread reparation after the joints wear.
Four, description of drawings
Accompanying drawing is a kind of example structure schematic diagram of the present utility model
Five, the specific embodiment
Consult accompanying drawing, a kind of job execution pipe comprises top connection 1 and lower contact 3 that body 2 and two ends thereof connect respectively.It is 5.08mm that top connection 1 is adopted pitch with lower contact 3, tapering 1: 6, the screw thread 4 of tooth depth 2.98mm.
Claims (2)
1. a job execution pipe comprises top connection and lower contact that body and two ends thereof connect respectively, it is characterized in that it is 5.08mm that pitch is adopted in described top connection and lower contact, tapering 1: 6, the screw thread of tooth depth 2.98mm.
2. job execution pipe according to claim 1 is characterized in that described top connection is a box, and lower contact is a pin thread.
