Abstract

The utility model relates to drill collar and in particular to a spiral drill collar with thickened middle of pipe body in drilling of petroleum, natural gas, water source, and mineral reserve in drilling technology. The utility model discloses a spiral drill collar with thickened middle of pipe body comprising a pipe body (1), a male joint (2), a female joint (3), and a thickening section of the pipe body (4), wherein the middle of the pipe body (1) is provided with the thickening section of the pipe body (4), the top end of the pipe body (1) being provided with a male joint (2), the terminal end being provided with a female joint (3), the male joint (2) and the thickening section of the pipe body (4) being provided with a spiral groove (1.1) therebetween, the female joint (3) and the thickening section of the pipe body (4) being provided with a spiral groove (1.1). The spiral drill collar with thickened middle of pipe body increases intensity of drill collar, prolongs service time of drill collar, and reduces resistance imposed on drill collar.

Description

The grooved drill collar of thickening in the middle of the body
(1) technical field
The utility model relates to a kind of drill collar, relates in particular to the 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.
(3) summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of can reduce the suffered resistance of drill collar effectively, and intensity is higher, and application life is longer, can protect the grooved drill collar of thickening in the middle of the body of male joint with imitating;
The purpose of this utility model is achieved in that
The grooved drill collar of thickening in the middle of a kind of body, it comprises: body, male joint, female joint and body thick section, 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.
The beneficial effect that the grooved drill collar of thickening has in the middle of the utility model body is:
The 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.
(4) description of drawings
Fig. 1 is the structural representation of the 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.
(5) specific embodiment
As Fig. 1, the utility model relates to the grooved drill collar of thickening in the middle of a kind of body, mainly form by body 1, male joint 2, female joint 3 and body thick section 4, 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, reduce the resistance that drill collar is subjected to by groove.

Claims (1)

1. the 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) and body thick section (4), 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).
