Abstract
The utility model relates to a drill collar, in particular to a wear-resistant spiral drill collar with a middle-thickened tube, which is mainly used for exploration of petroleum, natural gases, water sources and mineral resources and belongs to the technical of drilling machines. The wear-resistant spiral drill collar is characterized by comprising the tube (1), a male joint (2), a female joint (3), a tube thickened section (4) and wear-resistant welded strips (5). As the tube middle section of the wear-resistant spiral drill collar is thickened, strength of the drill collar is enhanced, vibration to the tube is reduced during drilling of the dill collar is reduced, service life of the drill collar is prolonged, further, as spiral grooves are arranged on the tube, sludge in a drilling well can be conveyed upwardly through the grooves, resistance to the drill collar is reduced, and the wear-resistant welded strips welded to the joints of the drill collar can function in wear resistance and corrosion resistance.
Description
(1) technical field
The utility model relates to a kind of drill collar, relates in particular to the wear-resisting grooved drill collar of thickening in the middle of a kind of body, is mainly used in the probing of oil, natural gas, water source, mineral reserve, belongs to the drilling rig technique field.
(2) background technology
In the drilling process of oil, natural gas, water source and mineral reserve, all need to use drill collar.Though the structure of drill collar is simple, its quality requirement that will reach is but than higher.Common drill collar is in the process of probing, and the impact that is subjected to is bigger, and the drill collar junction is given a shock damage easily.May also can cause drill collar work undesired for a long time in the past, even cause security incident; Drill collar is in the process of probing, and the mud in the soil can be extruded up, and drill collar is produced resistance, makes drill collar stressed bigger in work progress, is difficult for probing, and drill collar also very easily damages; Mud in the drilling well often contains and is corrosive, and can exert an influence to the drill collar joint place, can cause drill collar work undesired for a long time in the past.
(3) summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of can carry mud, can reduce the suffered resistance of drill collar effectively, and intensity is higher, the wear-resisting grooved drill collar that thicken in the middle of the longer pipe body application life.
The purpose of this utility model is achieved in that
The wear-resisting grooved drill collar of thickening in the middle of a kind of body, it is characterized in that: it comprises body, male joint, female joint, body thick section and wear resistance electrode, be provided with the body thick section in the middle of the described body, the top of described body is provided with male joint, end is provided with female joint, be provided with helical groove between described male joint and the body thick section, be provided with helical groove between described female joint and the body thick section, described male joint, female joint and body thick section are provided with wear resistance electrode.
The beneficial effect that the wear-resisting grooved drill collar of thickening has in the middle of the utility model body is:
The wear-resisting grooved drill collar of thickening has increased the intensity of drill collar to the thickening of body interlude in the middle of this body, has reduced the vibrations that body was subjected to when drill collar was drilled, and has prolonged the application life of drill collar; Body is provided with helical groove, can allow the mud in the drilling well up carry by groove, has reduced the resistance that drill collar is subjected to; The joint of drill collar is welded with wear resistance electrode, can play wear-resisting, erosion-resisting effect.
(4) description of drawings
Fig. 1 is the structural representation of the wear-resisting grooved drill collar of thickening in the middle of the utility model body.
Wherein: body 1, helical groove 1.1, male joint 2, female joint 3, body thick section 4, wear resistance electrode 5.
(5) specific embodiment
As Fig. 1, the utility model relates to the wear-resisting grooved drill collar of thickening in the middle of a kind of body, mainly form by body 1, male joint 2, female joint 3, body thick section 4 and wear resistance electrode 5, be provided with body thick section 4 in the middle of the described body 1, increased the intensity of drill collar, reduce the vibrations that have been subjected to when drill collar is drilled, prolonged the application life of drill collar.The top of described body 1 is provided with male joint 2, end is provided with female joint 3, be provided with helical groove 1.1 between described male joint 2 and the body thick section 4, be provided with helical groove 1.1 between described female joint 3 and the body thick section 4, can allow the mud in the drilling well up carry by groove, reduced the resistance that drill collar is subjected to, described male joint 2, female joint 3 and body thick section 4 are provided with wear resistance electrode 5, can play wear-resisting, erosion-resisting effect.
Claims (1)
1. the wear-resisting grooved drill collar of thickening in the middle of the body, it is characterized in that: it comprises body (1), male joint (2), female joint (3), body thick section (4) and wear resistance electrode (5), be provided with body thick section (4) in the middle of the described body (1), the top of described body (1) is provided with male joint (2), end is provided with female joint (3), be provided with helical groove (1.1) between described male joint (2) and body thick section (4), be provided with helical groove (1.1) between described female joint (3) and body thick section (4), described male joint (2), female joint (3) and body thick section (4) are provided with wear resistance electrode (5).
