Abstract
The utility model relates to the technical field of stabilizers, in particular to an ultra-short stabilizer. The ultra-short stabilizer comprises a body and abrasion-resistant layers; through holes are formed in the body, the outer side of the body is provided with at least two spiral lug bosses distributed on the circumference, mounting holes are distributed in the spiral lug bosses, hard alloy teeth are fixedly arranged in the mounting holes, and the abrasion-resistant layers are formed in the mounting holes; the lower end of the body is provided with a lower joint, and the lower joint is provided with a conical external thread; and the distance between the bottom of each spiral lug boss and the top of the conical external thread of the lower joint is between 20 and 150 millimeters. The ultra-short stabilizer is reasonable and compact in structure and convenient to use; and by shortening the distance between each spiral lug boss and the conical external thread, the distance between the abrasion-resistant layer outside each spiral lug boss and a drilling tool is shortened, so that the stabilizer plays a role in protecting a vertical drilling tool body in rotary drilling, and the anti-deviation drilling capability of the vertical drilling tool is enhanced.
Description
Technical field
the utility model relates to the stabilizer technical field, is a kind of ultrashort type stabilizer.
Background technology
The vertical drilling tool of
domestic independent research has been broken external monopolization to this technology, lets domestic drilling well field in this technical international most advanced level that is in; This instrument can initiatively be prevented oblique well straightening, and liberation the pressure of the drill improves drilling speed, has brought great economic benefit; In order better to bring into play the function of the drill tools deviation prevention and fast that hangs down, reduce the wearing and tearing of vertical drilling tool body, must connect stabilizer in the vertical drilling tool upper end, as the part of BHA; Use its wearing layer of prior standard stabilizer longer to the distance of lower contact; Even its wearing layer of stabilizer of nearly drill bit is still longer to the distance of lower contact; And wearing layer is long more apart from the vertical drilling tool distance; Be unfavorable for bringing into play the deviation prevention and fast effect of vertical drilling more, and the wearing and tearing that can not reduce the vertical drilling tool body.
Summary of the invention
the utility model provides a kind of ultrashort type stabilizer; Overcome the deficiency of above-mentioned prior art; It can effectively solve the deviation prevention and fast effect that the standard stabilizer is unfavorable for bringing into play vertical drilling, and the problem that can not reduce the vertical drilling tool body wear.
The technical scheme of
the utility model realizes through following measure: a kind of ultrashort type stabilizer comprises body and wearing layer; There is through hole inside at body, and there is the spiral boss of at least two circle distribution in the outside of body, on spiral boss, is distributed with installing hole, in installing hole, is installed with hard-metal insert and forms wearing layer; There is lower contact lower end at body, and conical external screw thread is arranged in the lower contact; Distance between the conical external screw thread top of the bottom of spiral boss and lower contact is between 20 millimeters to 150 millimeters.
Be to the further optimization of above-mentioned utility model technical scheme below or/and improve:
The lead angle angle of
above-mentioned spiral boss can be 30 °.
Can there be conical internal thread or external screw thread in the upper end of
above-mentioned body.
the utility model reasonable and compact in structure, easy to use; Through shortening the distance of spiral boss and conical external screw thread, the wearing layer in the spiral boss outside and drilling tool are shortened, thereby in rotary drilling, play the effect of protection vertical drilling tool body, strengthen the ability of the deviation prevention and fast of vertical drilling tool simultaneously.
Description of drawings
accompanying drawing 1 is looked the half section structural representation for the master of the utility model most preferred embodiment.
Coding in
accompanying drawing is respectively: 1 is body, and 2 is through hole, and 3 is spiral boss, and 4 is wearing layer, and 5 are lower contact, and 6 is conical external screw thread.
The specific embodiment
the utility model does not receive the restriction of following embodiment, can confirm concrete embodiment according to the technical scheme and the actual conditions of the utility model.
are in the utility model; For the ease of describing; The description of the relative position relation of each parts all is to describe according to the Butut mode of Figure of description 1, as: the position relation of upper and lower, left and right etc. is what to confirm according to the Butut direction of Figure of description.
Below in conjunction with embodiment and accompanying drawing the utility model is further described:
shown in accompanying drawing 1, this ultrashort type stabilizer comprises body 1 and wearing layer 4; In the inside of body 1 through hole 2 is arranged, there is the spiral boss 3 of at least two circle distribution in the outside of body 1, on spiral boss 3, is distributed with installing hole, in installing hole, is installed with hard-metal insert and forms wearing layer 4; In the lower end of body 1 lower contact 5 is arranged, conical external screw thread 6 is arranged in the lower contact 5; Distance between conical external screw thread 6 tops of the bottom of spiral boss 3 and lower contact 5 is between 20 millimeters to 150 millimeters.Lower contact 5 is connected with drilling tool through screw thread; Because the distance between the bottom of spiral boss 3 and conical external screw thread 6 tops of lower contact 5 is between 20 millimeters to 120 millimeters; Make the wearing layer 4 in spiral boss 3 outsides very near apart from drilling tool; When rotary drilling, can play the effect of protection vertical drilling tool body 1, strengthen the ability of the deviation prevention and fast of vertical drilling tool simultaneously.
Can according to actual needs above-mentioned ultrashort type stabilizer be done further to optimize or/and improve:
shown in accompanying drawing 1, the lead angle angle of spiral boss 3 is 30 °.
shown in accompanying drawing 1, have conical internal thread or external screw thread in the upper end of body 1.Being convenient to body 1 like this is connected with other devices.
above technical characterictic has constituted the most preferred embodiment of the utility model, and it has stronger compliance and best implementation result, can increase and decrease non-essential technical characterictic according to actual needs, satisfies the demand of different situations.
The use of
the utility model most preferred embodiment: because wearing layer 4 is very little to the distance of conical external screw thread 6; When connecting, use the tong of situ of drilling well to operate with vertical drilling tool; Therefore this stabilizer and vertical drilling tool be connected need factory building through on deduction accomplish; And then transport situ of drilling well to, as BHA G.I.H together, because wearing layer 4 is very near apart from vertical drilling tool; When rotary drilling, can play the effect of protection vertical drilling tool body, strengthen the deviation control with drilling straight well effect of vertical drilling tool simultaneously.
