Description
Technical field
The utility model relates to a kind of edge carbide button drift size gauge tool, for the drifting operation of Oil/gas Well formation testing (gas).
Background technology
In completion work progress, drifting operation is quite important, and it is the guarantee that big orifice completion tool is lowered into position smoothly.Situation about being hampered due to sleeve pipe problem during drifting mainly contains 3 clocks: the borehole wall exists cement sheath, sleeve pipe tie-back sleeve step, the interior burr existed of sleeve pipe of remnants when sweeping plug.
To be hampered situation for drifting, current processing mode mainly contains two kinds, but shortcoming is all comparatively obvious: one, adopt milling cone to carry out milling to sleeve pipe, its shortcoming is that this instrument is tapered, and the effective length of milling is inadequate; Two, adopt milling bucket process sleeve pipe, its shortcoming is for can not process sleeve pipe when drifting is hampered at once, and construction period is longer.
Summary of the invention
The purpose of this utility model is: provide a kind of edge carbide button drift size gauge tool, can either guarantee the effective length to wellbore treatments, can ensure again the ageing of well of constructing.
In order to achieve the above object, the utility model adopts following technical scheme:
Edge carbide button drift size gauge tool, comprise set gradually top connection, drift size gauge tool body and lower contact, described top connection, drift size gauge tool body and lower contact internal run-through, be provided with through hole vertically, the outer peripheral face of drift size gauge tool body is provided with the rhone of helical-type line; On the outer peripheral face of described drift size gauge tool body along its length, be provided with some strip carbide buttons.
Described strip carbide button is welded on the outer peripheral face of drift size gauge tool body.
The radial height of described strip carbide button exceeds drift size gauge tool body peripheral face 1 ~ 2mm.
The length direction that described strip carbide button runs through drift size gauge tool body is arranged.
The utility model compared with prior art, has following beneficial effect:
(1) the utility model is by the strip carbide button on body surface, the burr existed in the cement sheath in the borehole wall, sleeve pipe tie-back sleeve step, sleeve pipe can be processed, effective milling length of instrument can be ensure that, can process drifting to be immediately hampered complex situations again, guarantee to enter under later stage major diameter completion tool smoothly, ensure that the ageing of construction well.
(2) the utility model structure is simple, makes easily, with low cost, easy and simple to handle, and can repeatedly Reusability when ensureing to meet construction reference, saves production cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
Number in the figure represents: 1-top connection, 2-rhone, 3-carbide button, 4-body, 5-lower contact.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described in detail:
As shown in Figure 1, the utility model is a kind of edge carbide button drift size gauge tool, comprise set gradually top connection 1, drift size gauge tool body 4 and lower contact 5.The external diameter of top connection 1 be less than drift size gauge tool body 4 external diameter, for connecting sand clean out pipe string.Top connection 1, drift size gauge tool body 4 and lower contact 5, be provided with through hole vertically, flows out, carry out sand washing operation by the water in the sand clean out pipe string that top connection 1 connects from lower contact 5.The outer peripheral face of drift size gauge tool body 4 is provided with the rhone 2 of helical-type line, carries out water conservancy diversion by rhone 2 pairs of sand cleaning fluids, down-hole sand setting is fully stirred, improves the scouring effect to sand bridge, casting bed, guarantee successfully to take sand grains out of pit shaft.
Innovation of the present utility model is: on the outer peripheral face of drift size gauge tool body 4 along its length, be provided with some strip carbide buttons 3.This strip carbide button 3 run through drift size gauge tool body 4 length direction arrange, and strip carbide button 3 be adopt welding mode, be mounted on the outer peripheral face of drift size gauge tool body 4, strip carbide button 3 is connected as a whole with drift size gauge tool body 4.Except the mode of welding, strip carbide button 3 also can adopt other modes to be arranged in body 4 on the surface.The radial height of strip carbide button 3 exceeds drift size gauge tool body 4 outer peripheral face 1 ~ 2mm, and in this detailed description of the invention, the radial height of strip carbide button 3 exceeds drift size gauge tool body 4 outer peripheral face 1mm.
In this detailed description of the invention, process edge carbide button drift size gauge tool of the present utility model by code requirement, drift size gauge tool body about 4 external diameter is consistent, and its external diameter is less than casing inner diameter 6 ~ 8mm, and its drift size gauge tool body 4 length is not less than 1.5m, guarantees drifting effect.Edge carbide button drift size gauge tool body 4 is provided with the rhone 2 of 3 circle helical-type lines, be inlaid with 3 road carbide buttons 3, and 3 road carbide buttons 3 is symmetricly set on the outer peripheral face of drift size gauge tool body 4 simultaneously in 120 °.
Drift size gauge tool body 4 is mainly used in drifting, guarantees to enter under later stage completion tool smoothly; Carbide button 3 is strip, runs through whole drift size gauge tool body 4, and carbide button 3 plays the effect of milling footpath when being hampered.During drifting, any position of this edge carbide button drift size gauge tool is hampered, and can both be polished, then pass through smoothly by carbide button 3 to it.Carbide button 3 and drift size gauge tool body 4 are made into integration, its stable performance, there is not carbide button 3 and to fall the possibility of well, with drift size gauge tool body 4 being designed with 3 road rhones 2, the problem of whitewashing when solving lower major diameter instrument especially.
Using method of the present utility model is as follows:
Use top connection 1 jointed rod or oil pipe, transfer edge carbide button drift size gauge tool of the present utility model to assigned address, if be hampered, then rotate edge carbide button drift size gauge tool in the position that is hampered, by the carbide button 3 that drift size gauge tool body 4 is inlayed, process the burr etc. existed in the cement sheath in the borehole wall, sleeve pipe tie-back sleeve step, sleeve pipe, reach within regulation is hampered tonnage, transfer the object of jack rabbit smoothly.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above; above-mentioned embodiment just schematically; instead of restriction the utility model; in the ken that those of ordinary skill in the art possess; make various improvement under can not also departing from the prerequisite of the utility model aim, all belong to protection domain of the present utility model.
