Abstract
The utility model relates to a non -rotating stabilizer belongs to the oil drilling instrument, including the dabber body (1), the dabber body (1) surface cover has spacer (4), and it is right to set up the setting element on the dabber body (1) axial positioning is carried out in spacer (4), spacer (4) surface cover has the cover of support (3), supports cover (3) and both can also can rotate relatively by the coaxial line by axial displacement for spacer (4), the dabber body (1) one end is equipped with the auto -lock that is connected with the drilling rod and connects (5). Support the cover during well drilling and do not rotate along with the drilling string, support the effect that the cover only plays the support wall of a well to avoid the wearing and tearing of blade and the damage of the wall of a well, and can make the drill bit increase the heavy burden, improved well drilling speed, reduce the moment of torsion, reduce the drill collar wearing and tearing. It can quick replacement to support the cover to the support cover of different well sizes can be installed to same dabber.
Description
Technical field
The utility model belongs to oil drilling tool field, is specially a kind of non-ly to revolve stabilizer, can improve bit speed, reduce drilling cost.
Background technology
Drilling tool stabilizer (centralizer) is the important tool of inclining prevention change in oil drilling, requires relatively stricter, just lose due effect, more must renew stabilizer after outside dimension mill is little in drilling engineering to the work outside dimension of stabilizer.But traditional monolithic stability device wear-resistant strip wearing and tearing are than very fast, repair more difficult after wear-resistant strip wearing and tearing, application life is lower, and often bung down and need a lot of stabilizers, drilling cost is higher.Directly to contact with the borehole wall due to the blade of traditional monolithic stability device and rotate with drill string, so rotational resistance is larger in drilling process, and mud circulation also unimpeded not easy mud drum, easily cause the accidents such as difficulty or bit freezing that pull out of hole.Need in this case to develop a kind of novel drilling tool stabilizer, overcome the shortcoming of traditional integral stabilizer, reach the object reducing drilling cost.
Summary of the invention
The purpose of this utility model is to provide a kind of novel stabilizer, can reduce the wearing and tearing of conventional stabilizer, improve service efficiency, reduce drilling cost.The purpose of this utility model is achieved through the following technical solutions.
A kind of non-rotating stabilizer, comprise mandrel body, described mandrel body appearance surface cover has spacer, mandrel body is arranged keeper and carries out axial location to described spacer; Described spacer appearance surface cover has support set, and described support set both can move axially relative to spacer and also can relatively rotate by coaxial line; Described mandrel body one end is provided with the self-locking joint be connected with drilling rod.
Further, described mandrel body external surface and described spacer overlap side by side and have quoit, and end face and the endoporus of described quoit all have oil-way, and described keeper and described spacer are to quoit axial location.
Further, described quoit, spacer can coaxial rotation relative to mandrel body.
Further, described self-locking joint is the keeper of described quoit and spacer one end.
Further, described quoit material is copper.
Further, described support set comprises the cast steel lining of internal layer and the wear-resisting copper sheathing of inside surfacing and outer field rubber face.
Further, described self-locking joint has groove, support set has the tooth of protrusion, self-locking joint (5) coordinates with support set is castellated.
Further, the material of described spacer is carburizing steel.
Operating principle:
To be deducted points by drilling rod by mandrel body and self-locking joint in drilling process and do not form drilling assembly with boring very not to be connected, rotate with drill string when drill string rotating is crept into; And support set is altered in mandrel body by spacer, this kind connects support set and belongs to incomplete location, can rotate and slide up and down relative to mandrel body.When drill string rotating is crept into, the external diameter of support set contacts with the borehole wall, there is larger frictional force; Have oil lubrication between its internal diameter and mandrel body, frictional force is very little, so support set is do not rotate with drill string in drilling process.This kind of design makes drilling well resistance greatly reduce, and improves drilling efficiency, and support set again can quick-replaceable, greatly reduces drilling cost.
When support set chance card can not creep into, can carry drill string above, and reversely rotate drill string, at this moment the tooth of support set enters in the groove of self-locking joint, and clutch is closed, and support set can rotate unfreezing with drill string.
The beneficial effects of the utility model are:
(1) the utility model has structure advanced person compared with original one-piece auger stabilizer, and safe and reliable, righting is effective.
(2) the utility model long service life compared with original one-piece auger stabilizer, is convenient to installing/dismounting, is beneficial to maintaining.
Below in conjunction with the drawings and the specific embodiments, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
A kind of non-rotating stabilizer, comprise mandrel body 1, mandrel body 1 appearance surface cover has spacer 4, mandrel body 1 is arranged keeper and carries out axial location to described spacer 4; Spacer 4 appearance surface cover has support set 3, and support set 3 both can move axially relative to spacer 4 and also can relatively rotate by coaxial line; Mandrel body 1 one end is provided with the self-locking joint 5 be connected with drilling rod.
Mandrel body 1 external surface and spacer 4 overlap side by side quoit 2, and end face and the endoporus of quoit 2 all have oil-way, keeper and spacer 4 pairs of quoit 2 axial location.Quoit 2, spacer 4 can coaxial rotation relative to mandrel body 1, but can not move axially.Self-locking joint 5 is the keeper of quoit 2 and spacer 4 one end.Quoit 2 material is copper.
Support set 3 comprises the cast steel lining of internal layer and outer field rubber face.Support set 3 hangs abrasive rubber endoporus build-up wear-resistant copper sheathing by cast steel sleeve outer surface to process.
Self-locking joint 5 has groove, support set 3 has the tooth of protrusion, self-locking joint 5 coordinates with support set 3 is castellated.The tooth that support set 3 protrudes is arranged on cast steel lining, and in fact self-locking joint 5 and support set 3 are formed one " jaw clutch ".
The material of spacer 4 is carburizing steel.
Quoit 2 and spacer 4 are altered respectively in mandrel body 1, and support set 3 is altered on spacer 4, and self-locking joint 5 is connected with mandrel body 1 and links closely with assembling and disassembling stand.Inject lubrication oil by the upper oil hole of quoit 2, make spacer 4 and support set 3 sufficient lubrication, ensure that rubber sleeve is flexibly movable.Again by whole instrument access drilling assembly, implement drilling well work together with drilling assembly.
When support set 3 meet card can not creep into time, drill string can be carried above, and make drill string reversely rotate unfreezing.
