Abstract
The invention relates to the technical field of petroleum pipeline thread repairing, in particular to a novel API petroleum pipeline thread repairing and buckling method, which is implemented by the following steps: (1), taking a good first steel pipe, and performing API petroleum pipeline thread processing on the pipe end by a numerically-controlled machine tool according to the conventional method; (2), cutting off the length of L1 from the thread end face of the first steel pipe by an end face tool, and guaranteeing that the distance from a new thread end face to the end face of a chuck is L2. According to the novel API petroleum pipeline thread repairing and buckling method, abut-buckling is performed in a manner of rotating the chuck, thus the petroleum pipeline thread repairing operation is realized, the method is simple, the speed is high, the labor intensity of workers is effectively reduced, and the efficiency of repairing and buckling is greatly improved. In addition, the repairing and buckling method is applicable to all numerically-controlled systems, comprising commonly-used numerically-controlled systems of Fanuc and Simens in various types on the market currently.
Description
Technical field
The present invention relates to petroleum drilling rod screw-thread recovery technique field, be specifically related to new A PI oil pipe thread and repair button method.
Background technology
Nowadays, in oil, gas drilling process, drill string working condition very severe, drill string connecting joint is its weakest link.In drilling process, the connection screw thread of drill string joint is the most easily damaged, and drilling rod was lost efficacy.For the repairing of traditional API standard tool joint, the domestic engine lathe that generally adopts is manually repaired.Along with the development of drilling technology, deep-well, ultradeep well and strengthening drilling well are had higher requirement to the performance of tool joint.
Summary of the invention
The object of this invention is to provide a kind of method by rotary chuck and carry out make-up, thereby complete oil pipe thread repair, simple, the fireballing new A PI oil pipe thread of method is repaiied button method.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: new A PI oil pipe thread is repaiied button method, and described concrete steps are as follows:
(1), get a first good steel pipe, with Digit Control Machine Tool, according to conventional method, pipe end is carried out to the processing of API oil pipe thread;
(2), the screw thread end face L1 length of excising described the first steel pipe with end face cutter, guarantee that new screw thread end face is L2 length to the distance of chuck end face;
(3) under the prerequisite of, not unclamping at described chuck, on screw thread end face, find screw thread starting point, with marking pen, at the outer surface of described the first steel pipe, carry out the first steel pipe mark, on described chuck end face, on corresponding position, with marking pen, carry out chuck mark simultaneously;
(4), unload described the first steel pipe, load onto the second steel pipe that need to repair button;
(5), adopt chuck to clamp described the second steel pipe, with end face cutter, excise described the second steel tube screw thread end face L3 length, require to guarantee that new screw thread end face is L2 length to the distance of chuck end face, after end face processing, the screw thread starting point on the second Steel pipe end surface is carried out to the second steel pipe mark with marking pen;
(6), unclamp chuck, and rotary chuck, guarantees that the screw thread starting point of described the second steel tube screw thread end face overlaps with the gauge point orientation completing on chuck in above-mentioned steps (three), expansion chuck then, thereby complete the tool setting process that screw thread is repaiied button;
(7), adopt the screw thread procedure in above-mentioned steps (), the Z axis cutter of screwer is mended to chuck direction and is mended 2～3 integer pitch, starts numerical control program and repaiies button processing, thereby complete the button work of repairing.
The present invention has following beneficial effect: new A PI oil pipe thread of the present invention is repaiied button method, method by rotary chuck is carried out make-up, thereby completed oil pipe thread repair, and method is simple, speed is fast, effectively alleviated workman's labour intensity, greatly improved and repaiied button efficiency.In addition, this is repaiied button method and is applicable to all digital control systems, comprises the digital control system of conventional in the market FANUC and each model of SIMENS.
Accompanying drawing explanation
Fig. 1 is the first Steel tube standard screw thread end face excision L1 length rear thread starting point orientation diagram in the present invention.
Fig. 2 is the second steel pipe screw thread end face excision to be repaired L1 length rear thread starting point orientation diagram in the present invention.
Fig. 3 is after in the present invention, chuck rotates, the second steel pipe screw thread end face excision to be repaired L1 length rear thread starting point orientation diagram.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention will be further described in detail.
As shown in Figure 1, Figure 2, Figure 3 shows, new A PI oil pipe thread is repaiied button method, and described concrete steps are as follows:
(1), get a first good steel pipe 1, with Digit Control Machine Tool, according to conventional method, pipe end is carried out to the processing of API oil pipe thread; In process, to guarantee parameters, such as: the parameters such as tooth depth, pitch, accurate distance, tapering meet relevant criterion requirement;
(2), the screw thread end face L1 length of excising described the first steel pipe 1 with end face cutter, in the ordinary course of things, L1 length is that 5～10mm just can meet and repair button requirement, guarantees that new screw thread end face is L2 length to the distance of chuck 5 end faces;
(3), as shown in Figure 1, under the prerequisite of not unclamping at described chuck 5, on screw thread end face, find screw thread starting point, with marking pen, at the outer surface of described the first steel pipe 1, carry out the first steel pipe mark 3, on described chuck end face, on corresponding position, with marking pen, carry out chuck mark 4 simultaneously;
(4), unload described the first steel pipe 1, load onto the second steel pipe 2 that need to repair button;
(5), adopt chuck 5 to clamp described the second steel pipe 2, with end face cutter, excise described the second steel pipe 2 screw thread end face L3 length, here L3 length and above-mentioned L1 are equal in length, require like this to guarantee that new screw thread end face is L2 length to the distance of chuck 5 end faces, after end face processing, screw thread starting point on the second steel pipe 2 end faces is carried out to the second steel pipe mark 6 with marking pen, and now the screw thread starting point on the second steel pipe 2 end faces and the gauge point orientation on chuck 5 are as shown in Figure 2;
(6), unclamp chuck 5, and rotary chuck 5, guarantees that the screw thread starting point of described the second steel pipe 2 screw thread end faces overlaps with the gauge point orientation completing on chuck 5 in above-mentioned steps (three), then expansion chuck 5, thereby complete the tool setting process that screw thread is repaiied button; After completing tool setting process, the screw thread starting point of the second steel pipe 2 screw thread end faces and the gauge point orientation on chuck 5 are as shown in Figure 3;
(7), adopting the screw thread procedure in above-mentioned steps (), the Z axis cutter of screwer to mend to chuck 5 directions mends 2～3 integer pitch, starts numerical control program and repair button processing, thereby complete the button work of repairing.
Finally explanation is, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, other modifications that those of ordinary skills make technical scheme of the present invention or be equal to replacement, only otherwise depart from the spirit and scope of technical solution of the present invention, all should be encompassed in the middle of claim scope of the present invention.
