Description
Technical field
The utility model relates to thread cleaning engineering device technique fields, and in particular to a kind of casing internal screw thread cleaning device.
Background technique
Casing is the important component of oil/gas well.Single casing is a length of 10 meters general, and hundreds of casings are connected by screw thread
It is connected together, from ground, the subterranean oil gas-bearing formation that goes directly to form the migration pathway of oil gas provides possibility for the production of oil gas.Set
Pipe screw thread is a kind of special cone seal screw thread, its integrality and spatter property are directly related to the success or failure for being drilled well operations.
Since Jing Qianduo deposits in outdoor place to casing from dispatching from the factory to entering, and the resting period is longer, during this period of time casing by
The factors such as wind, rain beat, solarization influence, and casing threads surface is easily stained with the foreign matters such as booty, hard particles object, if in connection spiral shell
These foreign matters are not cleaned up when line, influence the performances such as leakproofness and the bonding strength of screw thread, cause security risk to underground.Institute
With in the drilling well preparation stage, cleaning screw thread is one of most important preparation, but the cleaning method of casing threads also compares at present
It is more original, it is mainly wiped by hand with wire brush and cotton, time-consuming and laborious not say, effect also cannot be guaranteed.
Summary of the invention
It is clear to solve existing casing threads the purpose of this utility model is to provide a kind of casing internal screw thread cleaning device
Wash problem time-consuming, laborious, that effect is poor.
To achieve the above object, the utility model provides a kind of casing internal screw thread cleaning device comprising shaft, righting
Device and cleaning assembly, the front end of the shaft are equipped with mechanical connection hole, and the centralizer is rotatably affixed to the shaft
Middle section, the cleaning assembly includes adjusting rod and cleaning brush, is equipped with the perforation of adjusting in the back segment of the shaft, described
Adjusting rod is moveably secured to the perforation, and one end of the adjusting rod is fixed with nut, the other end of the adjusting rod
It is fixed with the cleaning brush, the bristle of the cleaning brush is arranged outwardly, in the cleaning brush to the tune between the shaft
Pole is equipped with spring.
Wherein, the cleaning assembly is equipped with multiple, and multiple cleaning assembly are circumferentially uniformly distributed along the shaft and along described
The setting of shaft axile displacement.
Wherein, there are two the cleaning assembly is set, two cleaning assembly are circumferentially symmetrical arranged along the shaft.
Wherein, the spring is compressed spring.
Wherein, the centralizer is detachably secured to the shaft.
The utility model has the advantages that
Casing internal screw thread cleaning device provided by the utility model, power source (pneumatic impact spanner) pass through mechanical connection Kong Yuzhuan
Axis is connected, and to provide machine power, cleaning operation is made to save manpower, centralizer guarantees steady when shaft and cleaning assembly rotate
Fixed, the spring in cleaning assembly makes the cleaning brush moment be close to screw thread, ensure that the active force between cleaning brush and screw thread, improves
The effect of cleaning, generally saves the time, achievees the purpose that time saving and energy saving effect is good.
Detailed description of the invention
Fig. 1 is the casing internal screw thread cleaning device structural schematic diagram that embodiment 1 provides.
Fig. 2 is the axonometric drawing of Fig. 1.
In figure: 1- shaft, 2- centralizer, 3- adjusting rod, 4- nut, 5- cleaning brush, 6- spring, 7- are mechanically connected hole.
Specific embodiment
The following examples illustrate the utility model, but is not intended to limit the scope of the present invention.
Embodiment 1
Embodiment 1 provides a kind of casing internal screw thread cleaning device, as illustrated in fig. 1 and 2 comprising shaft 1, centralizer 2
And cleaning assembly, the front end of shaft 1 are equipped with mechanical connection hole 7, centralizer 2 is rotatably affixed to the middle section of shaft 1, righting
The maximum outer circle of device 2 is fitted closely with the seam allowance inner wall of casing internal screw thread, and cleaning assembly includes adjusting rod 3 and cleaning brush 5,
The back segment of shaft 1 is equipped with the perforation of adjusting, and adjusting rod 3 is moveably secured to perforate, and one end of adjusting rod 3 is fixed with spiral shell
Mother 4, the other end of adjusting rod 3 is fixed with cleaning brush 5, and the bristle of cleaning brush 5 is arranged outwardly, in cleaning brush 5 between shaft 1
Adjusting rod 3 is equipped with spring 6.
In use, pneumatic impact spanner (drilling team is spare) is connect by being mechanically connected hole 7 with shaft 1, centralizer 2 is inserted into casing
Internal screw thread starting point seam allowance, centralizer 2 and seam allowance inner wall be fitted close, and guaranteeing will not when shaft 1 and cleaning assembly rotate
Bias drives shaft 1 to rotate, to make cleaning assembly around sleeve rotating, using cleaning brush 5 to cannula tip by pneumatic impact spanner
Internal screw thread complete cleaning, operate it is time saving and energy saving, cleaning speed is fast, under the action of spring 6, cleaning brush 5 be close to casing threads,
Cleaning dynamics are strong, and cleaning effect is good.Since casing threads is taper thread, it is in the starting point of screw thread and the nominal diameter of trailing end
Different, need to adjust the position of cleaning brush 5 constantly, in the process of cleaning to guarantee that 5 moment of cleaning brush is close to screw thread, this implementation
The casing internal screw thread cleaning device of example, the design of spring 6 is so that whether in cleaning screw initial thread end or the ending of screw thread
End, cleaning brush 5 can be close to thread surface always, and cleaning effect is good, and does not need the position for adjusting cleaning brush 5 at any time, side
Just it operates.
In the present embodiment, cleaning assembly is equipped with multiple, and multiple cleaning assembly are circumferential uniformly distributed along shaft 1 and along 1 axis of shaft
To shifting to install.
Embodiment 2
Embodiment 2 provides another casing internal screw thread cleaning device, and structure is essentially identical with embodiment 1, below
Only difference is pointed out to be described.
In the present embodiment, there are two cleaning assembly is set, two cleaning assembly are circumferential arranged symmetrically along shaft 1, centralizer 2
It is detachably secured to shaft 1, since cleaning assembly is inherently dismountable, so casing internal screw thread provided in this embodiment
Cleaning device each section is to be detachably connected, and any a part is damaged, such as corrosion damage, by replacing the part zero
Part, so that it may realize the reparation to the tool, save the economic expenditure of use side.
Although above having made detailed description to the utility model with generality explanation and specific embodiment,
On the basis of the utility model, it can be made some modifications or improvements, this is apparent to those skilled in the art
's.Therefore, these modifications or improvements on the basis of without departing from the spirit of the present invention, belong to the utility model and want
Seek the range of protection.
