Abstract
An integral type double-shoulder sulfur resistant drill rod is applied in petroleum drilling. An external thread joint and an internal thread joint are rolled at two ends of a drill rod body respectively, and the external thread joint, the internal thread joint and the drill rod body are integrated; a conical surface transitional zone is arranged between the outer wall at one end of the drill rod body and the outer wall of the external thread joint, as well as between the outer wall of the other end of the drill rod body and the outer wall of the internal thread joint; an external thread shoulder surface, external threads and an external thread end surface are processed at the end part of the external thread joint; and an internal thread end surface, internal threads and an internal thread shoulder surface are processed at the end part of the internal thread joint. The double-shoulder sulfur resistant drill rod has the benefits that the internal thread joint and the external thread joint of the drill rod and the drill rod body are all made of the same H2S stress corrosion resistant material through rolling and conventional sulfur resistant drill rod welding processing technique is not adopted, so as to improve the integral H2S stress corrosion resistant capability of the sulfur resistant drill rod, remarkably shorten processing period, and guarantee superior torsional strength of the sulfur resistant drill rod due to the double-shoulder structure.
Description
Technical field
The utility model relates to the drilling rod that oil drilling is used, and relates in particular to the two shoulder sulfur resistant drill pipes of a kind of monolithic.
Background technology
At present, the sulfur resistant drill pipe of acid-soluble oil gas field exploitation usefulness is welded by male connection, the female adapter at drill pipe body and two ends.The internal and external screw thread joint at drill pipe body and two ends adopts the anti-H of different grade of steels respectively
2S stress corrosion materials processing forms, and by the friction flat welding process drill pipe body and nipple is fixed together then; Heat-treat the performance of improving the weld zone by the butt welded seam position then.Because the characteristics of welding procedure self make the anti-H at sulfur resistant drill pipe weld seam position
2S stress corrosion ability is starkly lower than body and joint area, becomes the weakest position of whole sulfur resistant drill pipe, also is the position of the easiest generation stress corrosion fracture.The low anti-H of weld seam
2The huge obstacle that S stress corrosion ability becomes the research and development of restriction sulfur resistant drill pipe and applies.
The utility model content
The purpose of this utility model is: provide a kind of monolithic two shoulder sulfur resistant drill pipes, the two shoulder sulfur resistant drill pipes of monolithic that adopt whole rolling method to process do not adopt conventional sulfur resistant drill pipe technique for welding, improve the whole anti-H of sulfur resistant drill pipe
2S stress corrosion ability guarantees that by two shoulder structures sulfur resistant drill pipe has higher torsional strength simultaneously.
The technical solution adopted in the utility model is: the two shoulder sulfur resistant drill pipes of monolithic, mainly form by drill pipe body, male connection and female adapter, drill pipe body, male connection and female adapter have centre bore, it is characterized in that: male connection and female adapter are rolling respectively at the two ends of drill pipe body, and male connection, female adapter and drill pipe body are one.Between the outer wall of drill pipe body one end outer wall and male connection the conical surface transition band is arranged; The conical surface transition band is arranged between the outer wall of drill pipe body other end outer wall and female adapter.Be processed with external screw thread circular bead surface, external screw thread and external screw thread end face in the male connection end; Be processed with internal thread end face, internal thread and internal thread circular bead surface in the female adapter end.
The tapering of the conical surface transition band of described male connection is 75 degree; The tapering of the conical surface transition band of female adapter is 36 degree.
Drill pipe body, male connection and female adapter adopt E-75 or X-95 material to be rolled into.
The two shoulder sulfur resistant drill pipes of monolithic adopt anti-H
2The material of S stress corrosion is by rational rolling mill practice global formation, and female adapter and male connection will have enough length to repair the space to guarantee sufficient tong grasping part and screw thread.
The beneficial effects of the utility model: the two shoulder sulfur resistant drill pipes of the utility model monolithic, drill pipe box, male connection and drill pipe body are by with a kind of anti-H
2The material of S stress corrosion is rolling to form, and does not adopt conventional sulfur resistant drill pipe technique for welding, improves the whole anti-H of sulfur resistant drill pipe
2S stress corrosion ability, and obviously reduced the process-cycle, guarantee that by two shoulder structures sulfur resistant drill pipe has higher torsional strength simultaneously.

Among the figure, 1. drill pipe body, 2. male connection, 3. female adapter, the 4. conical surface, 5. external screw thread circular bead surface, 6. external screw thread, 7. external screw thread end face, 8. internal thread end face, 9. internal thread, 10. internal thread circular bead surface.
The specific embodiment
Embodiment 1: with the two shoulder sulfur resistant drill pipes of a monolithic is example, and the utility model is described in further detail.
Consult Fig. 1.The two shoulder sulfur resistant drill pipes of the utility model monolithic mainly are made up of drill pipe body 1, male connection 2 and female adapter 3, and drill pipe body 1, male connection 2 and female adapter 3 have centre bore, and centre bore is the drilling mud passage.Rolling respectively the two ends of male connection 2 and female adapter 3 at drill pipe body 1.It is one that male connection 2, female adapter 3 and drill pipe body 1 adopt the X-95 material rolling.Between the outer wall of drill pipe body 1 one end outer walls and male connection 2 conical surface transition band 4 is arranged, conical surface transition band 4 taperings of male connection 2 are 75 degree.Between the outer wall of drill pipe body 1 other end outer wall and female adapter 3 conical surface transition band 4 is arranged, conical surface transition band 4 taperings of female adapter 3 are 36 degree.Be processed with external screw thread circular bead surface 5, external screw thread 6 and external screw thread end face 7 in male connection 2 ends; Be processed with internal thread end face 8, internal thread 9 and internal thread circular bead surface 10 in female adapter 3 ends.What male connection 2 and female adapter 3 were adopted is the API standard.
