Description
Technical field
Petroleum drilling engineering field is the utility model is related to, particularly a kind of drilling string stabilizer for slowing down jarring.
Background technology
, can be by setting in drill string to ensure that institute's bored borehole forms well according to engineering design requirements during wellbore construction
Meter requires to access appropriate drilling string stabilizer, but existing drilling string stabilizer does not possess anti-sticking and unfreezing function, drilling string stabilizer
Can with drill string tripping in bored borehole, when bore meet slim-hole when, can be in card column drill string and during sillar prominent in well
The drilling string stabilizer of access, due to be swept away by force in the case of not knowing on ground into, wait ground instrument reaction and operating personnel hair
Now, drill string has been stuck, and particularly in underground situation complexity, tripping in is more prone to the generation for the above situation occur, therefore,
It is imperative to design brand-new drilling string stabilizer.
The content of the invention
For the above situation, to solve the defect of prior art, the purpose of the utility model is just to provide one kind and slows down shake
The drilling string stabilizer hit, can effectively solve drilling string stabilizer and enter slim-hole with the drill string during making a trip in drilling process
With problem the occurrence of borehole wall projection.
The technical scheme that the utility model solves is, including upper body, spring, centralizer body and lower body, and upper body top sets to be interior
The cylinder of step, bottom are multiple edge body, are set with the first compression spring, centralizer body, the second compression spring, upper body successively thereon
The pin thread screw thread that bottom is provided with is together with the box screw thread spinning of lower body upper end, and centralizer body inwall is multiple edge body, with upper body
The multiple edge body of bottom matches, and prominent conveyor screw is evenly equipped with outer wall, and is respectively provided with the step surface of centralizer body upper and lower side two
One compression spring, the second compression spring, can make centralizer body be maintained at the middle part of upper body bottom multiple edge body.
The utility model structure novel and unique, advantages of simple, using effect is good, improves the security of instrument, extends
Service life, can effectively take rapidly to put to put drill string progress jarring and operate releases its drill string accident, meets scene reality
Demand, drilling safety environment and production work efficiency are effectively improved, is the innovation on drilling string stabilizer.
Brief description of the drawings
Fig. 1 is structural profile illustration of the present utility model.
Fig. 2 is structural representation of the present utility model.
Embodiment
Specific embodiment of the present utility model is described in further detail below in conjunction with accompanying drawing.
Provided by Fig. 1-2, the utility model includes upper body, spring, centralizer body and lower body, and upper body top sets step to be interior
Cylinder, bottom are multiple edge body, are set with the first compression spring 2a, centralizer body 3, the second compression spring 2b, upper body successively thereon
For the pin thread screw thread that bottom is provided with together with the upper end box screw thread spinning of lower body 6, the inwall of centralizer body 3 is multiple edge body, and upper
The multiple edge body of body bottom matches, and prominent conveyor screw 5 is evenly equipped with outer wall, is filled respectively in the step surface of 3 upper and lower side of centralizer body two
There are the first compression spring 2a, the second compression spring 2b, centralizer body 3 can be made to be maintained at the middle part of upper body bottom multiple edge body, work as drill string
Descending with drill string after stabilizer is connected on drill string, when meeting slim-hole, centralizer body 3 is obstructed, and compresses the first compression spring
2a, slow down the hard collision with slim-hole, when centralizer body 3 is stuck at slim-hole, body is put on drill string with the up upper pressure of drill string the
One compression spring 2a and on hit centralizer body 3 and unfreezing, when drill string above carries, on top, well section slim-hole is hampered, and centralizer body 3 compresses
Second compression spring 2b slows down the hard collision with slim-hole, and when centralizer body 3 is stuck at slim-hole, drill string transfers upper body with drill string
Push the second compression spring 2b and under hit centralizer body 3 and unfreezing, drill string is normally in drilling, because centralizer body 3 is to be sleeved on upper body
Bottom, the impact endurance test shock to the borehole wall from drill string can be reduced.
In order to ensure using effect, it is described it is upper have through hole in vivo, upper end is provided with the box thread for being easy to be connected with drill string
Button.
Described lower body 6 is the threaded hollow circular cylinder in both ends, and cylindrical upper end is in step-like, upper end box screw thread
It is connected with upper body bottom pin thread screw thread, the first compression of the centralizer body 3 and suit of suit outside box step limitation upper body
Spring 2a, the second compression spring 2b are dropped out, and ensure that they are set with the limits prescribed.
Described upper body bottom, the inwall of centralizer body 3 are 6-8 rib bodies.
Described conveyor screw 5 is 3-5.
The described surface of conveyor screw 5 is provided with the hole of insert carbide button 4, and carbide button 4 is cylinder, is fitted in by tight fit
In hole on conveyor screw 5, it is therefore an objective to for the wearability of increase conveyor screw 5.
Service condition of the present utility model is that the damping assembled is slowed down into jarring drilling string stabilizer is connected by design requirement
Enter onto drill string, descending with drill string when boring instantly, when meeting slim-hole, centralizer body 3, which is obstructed, then compresses upper spring 2a, slows down
With the hard collision of slim-hole, when centralizer body 3 is stuck at slim-hole, put on drill string body with spring 2a in the up pressure of drill string and on
Hit centralizer body 3 and unfreezing.When pulling out of hole, on top, well section slim-hole is hampered when above carrying drill string, and centralizer body 3 compresses lower spring 2b and subtracted
The slow hard collision with slim-hole, when centralizer body 3 is stuck at slim-hole, drill string transfer upper body with pressing spring 2b under drill string and under hit
Centralizer body 3 and unfreezing.When normal drilling, because centralizer body 3 is the bottom that is sleeved on upper body, can reduce to drill string to the borehole wall
Impact endurance test shock.Application of the jarring drilling string stabilizer on drill string is slowed down by damping, conventional damping is preferably resolved and slows down
The problem of jarring, the security of instrument is improved, extends service life.
The utility model structure novel and unique, advantages of simple, strengthen drilling string stabilizer damping in drilling process and slow down jarring
Ability, security is enhanced, and can timely and effectively reduce bit freezing probability, improved the problem of live operability, reduce
The generation of drilling well underground engineering accident, easy to use, effect is good, is the innovation on drilling well stabilizer, have good economy and
Social benefit.
