Abstract
The utility model relates to a three-segment spiral extra-heavy drill rod, which consists of a male connector, wear-resisting belts, diameter mutation segments, pipe bodies, a thickening and overstriking middle segment and a female connector, wherein the thickening and overstriking middle segment is arranged at the interval of the pipe bodies; the upper parts and the lower parts of the pipe bodies at the upper end and the lower end are respectively provided with the diameter mutation segments; the upper parts and the lower parts of the upper and the lower diameter mutation segments are respectively provided with the wear-resisting belts; and the upper parts and the lower parts of the upper and the lower wear-resisting belts are respectively provided with the male connector and the female connector. The drill rod has reasonable design, novel structure and reliable working, and has the advantages of easy manufacturing and processing, long service life, good effect and the like; and with the adoption of the drill rod, the high-efficient normal drilling constructions of a highly-deviated well and a horizontal well can be ensured.
Description
Technical field:
The utility model relates to a kind of instrument that is used for petroleum drilling engineering.Belong to petroleum drilling technology and instrument class.
Background technology:
Heavy weight drill pipe is one of important tool in the Process of Oil Well Drilling, length is generally at 9.1-9.6 rice, wall thickness is between drill collar and drilling rod, generally about one inch, in drilling assembly between drill collar and drilling rod, its flexibility also between drill collar and drilling rod, is utilized it can avoid because the vibration of drill collar is directly conducted to drilling rod and causes the drilling rod frequent failure, and then is caused drilling failure.At present, overstriking section in the middle of the on-the-spot heavy weight drill pipe that uses has only a section by standard code, this overstriking section belongs to the section of setting upright of heavy weight drill pipe, and is better for the straight well effect that gradient is less.Yet then can not adapt to for high angle hole and horizontal well.Because in drilling process, heavy weight drill pipe is more crisp hard, under extruding, high speed rotation, circulation moment of torsion and the flexural stress of shaft bottom crag, the diameter mutable site ruptures easily, and normally causing of wellbore construction had a strong impact on.
The utility model content:
The purpose of this utility model is to provide a kind of guarantee the effectively three-section type spiral heavy weight drill pipe of work thereby can reduce its diameter sudden change section degree of crook in high angle hole or horizontal well drilling process, improve the shaft bottom force-bearing situation.
The utility model purpose is to realize like this, this kind three-section type spiral heavy weight drill pipe is made up of male joint, wear-resisting band, diameter sudden change section, body, thickening overstriking interlude and female joint, its structure assembled relation is as follows: be interval with thickening overstriking interlude between each section body, body upper and lower in two ends is respectively equipped with diameter sudden change section up and down, upper and lower diameter sudden change section upper and lower is respectively equipped with wear-resisting band, and upper and lower wear-resisting band upper and lower is respectively equipped with male joint and female joint.The making process of common heavy weight drill pipe is: raw material alignment-boring-turning-ultrasonic testing/ ultrasonic examination-heat treatment-ultrasonic testing/ ultrasonic examination-turn taper-cutting thread-Che increases the weight of cylindrical-weld wear-resisting band-screw thread magnetic powder inspection-mark.Making process of the present utility model is consistent with above-mentioned basic process, but processes three sections thickening overstriking interludes on the turning operation, and each thickening overstriking interlude and body are rounding off, and mill out three road helicla flutes on the thickening overstriking section.
The utility model is reasonable in design, novel structure, and reliable operation has and is easy to make processing, long service life, advantage such as effective, utilizes it can guarantee efficiently normally carrying out of high angle hole and horizontal well drilling construction.
Description of drawings:
Fig. 1 is a general structure schematic diagram of the present utility model.
This kind of Fig. 2 heavy weight drill pipe underground work view.
The specific embodiment:
Below in conjunction with accompanying drawing enforcement of the present utility model is illustrated.
As shown in the figure, this kind three-section type spiral heavy weight drill pipe by male joint 1, wear-resistingly be with 2,12, diameter sudden change section 3,11, body 4,6,8,10, thickening overstriking interlude 5,7,9 and female joint 13 form. wherein, process three sections overstriking thickening interludes 5,7,9 between the body 4,6,8,10, mill out three sections right hand helix grooves respectively on every section thickening overstriking interlude, it between each thick section and the body rounding off, be beneficial to mud and pass through, and the power that upwards returns out well head is provided in rotary course, for mud and entrained landwaste thereof.
