Abstract
The utility model discloses a horizontal directional traversing guiding device, and aims to solve the problem that the original wellhole can not be broken through since the front end of a drill rod can easily plunge into the wall of the wellhole when the drill rod is required to be fed into the well without drill rods. The guiding device comprises a drill rod body, wherein a threaded port is arranged at the rear end part of the drill rod body, a float adopting a cylindrical closed structure is arranged at the front end part of the drill rod body, the front end of the drill rod body is positioned in and fixedly connected with the float, and conic heads are arranged at both ends of the float. After the float is arranged at the front end of the drill rod, when a drill rod is fed into the well, the front end of the drill rod is always kept in the middle of an aperture passage by virtue of the buoyant force applied to the float by sludge in the well, so as to prevent the front end of the drill rod from plunging into the wall of the wellhole. The conic heads at both ends of the float can take an excellent guiding effect on the advancement or withdrawal of the drill rod, so as to ensure that the original wellhole can be broken through.
Description
Technical field
The utility model relates to a kind of horizontal directional drilling pipeline crossing construction device, and particularly a kind of horizontal orientation passes through guiding device.
Background technology
In the prior art, the drilling rod middle part is provided with the mud duct of perforation along its length, and two ends of drill is respectively equipped with hickey, so that interconnect between the drilling rod.In horizontal orientation crossing construction process, particularly in the reaming construction of rock strata crossing and bad ground, tend to occur the down-hole accident of drilling tool fracture, cause no drilling rod in the well, need advance bar again, existing drilling rod is when advancing bar again, the drilling rod leading section is pricked easily on hole wall, and especially at the turning, duct, easier generation drilling rod leading section is pricked people's hole wall and caused and can not move on, thereby cause to connect former wellhole, cause former wellhole to scrap.
The utility model content
For solving in the prior art, drilling rod penetrates hole wall easily when advancing bar again causes connecting former wellhole, the problem that causes former wellhole to scrap, and the utility model provides a kind of horizontal orientation to pass through guiding device, can connect former wellhole easily.
For solving above technical problem, a kind of horizontal orientation provided by the utility model passes through guiding device, comprise the drilling rod body, the rearward end of drilling rod body is provided with hickey, the leading section of drilling rod body is provided with floating drum, described floating drum is the cylinder enclosed construction, and the front end of drilling rod body is arranged in floating drum and both are fixedly connected.
As improvement of the present utility model, the two ends of described floating drum are equipped with nose cone.
With respect to prior art, the utility model has been obtained following beneficial effect: after the drilling rod front end is provided with floating drum, when advancing bar again, because the buoyancy that the mud in the wellhole produces floating drum, make the drilling rod front end be positioned at the middle part in duct all the time, avoided the drilling rod front end to prick people's hole wall.Two ends at floating drum are provided with nose cone, advancing or retreating all and can play good guide effect drilling rod.
Description of drawings
Fig. 1 passes through the structural representation of guiding device for the utility model horizontal orientation.
Among the figure: nose cone behind 1 drilling rod body, 1a mud duct, 1b hickey, 2 floating drums, 2a front cone head, the 2b.
The specific embodiment
As shown in Figure 1, horizontal orientation of the present utility model passes through guiding device, comprise drilling rod body 1, the rearward end of drilling rod body 1 is provided with hickey 1b, the leading section of drilling rod body 1 is provided with floating drum 2, and floating drum 2 is the cylinder enclosed construction, and the front end of drilling rod body 1 is arranged in floating drum 2 and both are fixedly connected, the two ends of floating drum 2 are respectively equipped with front cone head 2a and back nose cone 2b, and front cone head 2a front end is provided with swivel.
In horizontal orientation crossing construction process, in well, there is not drilling rod, in the time of need advancing bar again, horizontal orientation of the present utility model is passed through guiding device be contained in the most last joint, because the leading section of drilling rod body 1 is equipped with floating drum 2, the buoyancy that mud in the wellhole produces floating drum 2 makes the front end of drilling rod body 1 be positioned at the middle part in duct all the time, has avoided the drilling rod front end to prick people's hole wall.The nose cone at floating drum 2 two ends to the advancing or retreat all and can play good guide effect of drilling rod, thereby can guarantee that drilling rod can connect former wellhole, can not cause former wellhole to scrap.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all fall into the protection domain of the utility model requirement.
Claims (2)
1. a horizontal orientation passes through guiding device, comprises the drilling rod body, and the rearward end of drilling rod body is provided with hickey, it is characterized in that, the leading section of drilling rod body is provided with floating drum, and described floating drum is the cylinder enclosed construction, and the front end of drilling rod body is arranged in floating drum and both are fixedly connected.
