Abstract
The utility model relates to a well drilling matching tool for a highly-deviated well, a horizontal well and an extended reach well, and particularly relates to a spiral redressing and expanding tool. An upper connector, an upper spiral centralizer, a lower spiral centralizer, and a lower connector which are arranged on the tool are integrally formed and a water hole is formed in the center of the tool. A stress groove is formed between the upper spiral centralizer and the lower spiral centralizer. Spiral working belts are arranged on the outer surface of the upper spiral centralizer and the outer surface of the lower spiral centralizer. Polycrystalline diamond compacts (PDC) clad sheets are inlaid at the upper ends and the lower ends of the spiral working belts, and wearable alloy columns are inlaid evenly on working faces of the spiral working belts. According to the spiral redressing and expanding tool, effective well wall finishing, rock debris wall and micro step removing, well hole shrinkage preventing, and well hole smoothness maintaining are achieved, and the shortcomings that good redressing and well wall finishing functions are incapable of being achieved through the prior centralizer are overcome.
Description
Technical field:
The utility model relates to a kind of high angle hole, horizontal well, extended reach well drilling well kit, particularly a kind of spiral reaming hole enlargement tool.
Background technology:
At present, in the construction of the exceptional well types such as high angle hole, horizontal well, extended reach well, when being drilled into hole instability or the stratum of undergauge easily occuring, such as untimely reaming, the finishing borehole wall, hole shrinkage very easily occuring, gently then be hampered, then causes the complex accident such as bit freezing, well filling, bury drills tool when serious.And existing centralizer can only carry out simple drifting, can't realize the effect of good reaming and the finishing borehole wall.
The utility model content:
The technical problems to be solved in the utility model provides a kind of spiral reaming hole enlargement tool, and this instrument has realized effectively repairing the borehole wall, and Cutting Disposal and little step are avoided hole shrinkage, keeps well smooth.Overcome existing centralizer and can't realize the deficiency of good reaming and the effect of the finishing borehole wall.
Technical solution adopted in the utility model is: a kind of spiral reaming hole enlargement tool comprises top connection and lower contact; Top connection, upper spiral centering device, lower spiral centering device, the machine-shaping of lower contact one and therein the heart have hydrophthalmia, be processed with the stress groove between upper spiral centering device and the lower spiral centering device, be processed with spiral work band on upper spiral centering device and the lower spiral centering device external surface, spiral work band upper/lower terminal is inlaid with the PDC composite sheet, is inlaid with equably the antifriction alloy post on the work plane of spiral work band.
The beneficial effects of the utility model are: the utility model is inlayed the mode of PDC composite sheet and antifriction alloy post owing to having adopted at spiral work band, thereby has the finishing borehole wall, and the function of Cutting Disposal and little step is avoided hole shrinkage, keeps well smooth.
Description of drawings:
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of spiral work band.
The specific embodiment:
As shown in Figure 1 and Figure 2, a kind of spiral reaming hole enlargement tool comprises top connection 1 and lower contact 8; Top connection 1, upper spiral centering device 2, lower spiral centering device 3, lower contact 8 one machine-shapings and therein the heart have hydrophthalmia 7, there is not screwed connection in the middle of this instrument, ensured the intensity of instrument, be processed with the stress groove between upper spiral centering device 2 and the lower spiral centering device 3, avoided stress to concentrate the instrument that causes to damage.Be processed with spiral work band 4 on upper spiral centering device 2 and lower spiral centering device 3 external surfaces, spiral work band 4 upper/lower terminals are inlaid with PDC composite sheet 6, are inlaid with equably antifriction alloy post 5 on the work plane of spiral work band 4.Lower spiral centering device 3 has played the effect of the cutting borehole wall in drilling process, upper spiral centering device 2 has played the effect of eliminating little step, the finishing borehole wall, and the runner of spiral centering device is wide, can be well with the landwaste migration of down-hole and leave the shaft bottom, effectively purified well, reduce the generation of down hole problem, reduced the risk of drilling well.
Be understandable that, more than about specific descriptions of the present utility model, only for the utility model being described and being not to be subject to the described technical scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can make amendment or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as satisfy, all within protection domain of the present utility model.
