Description

Cleaner for female drill pipe buckles

Technical Field

The utility model relates to a drilling rod box clearance ware.

Background

In oil drilling operations, a large number of drilling tools, including drill pipes, drill collars, subs, etc., are used, the primary function of which is to transmit bit pressure and rotational torque to the drill bit and to deliver mud downhole during the drilling of rock formations. The connection and the sealing between the drilling tools are realized by the connection of the screw threads of the drilling tools, and the screw thread parts generally have mud and detritus attached due to the severe working environment of the drilling tools, so that the drilling tools have the risks of screw thread puncture, thread release, breaking and the like under the conditions of high-pressure mud washing and high-torque rotation in the drilling process if the screw threads of the drilling tools are not thoroughly cleaned before the connection. Drilling tool downhole accidents can seriously affect project progress, increase operation cost, even result in whole well scrapping and the like. It is therefore necessary to thoroughly clean the threaded end faces before the drill is connected.

At present, two common cleaning modes of the screw thread of the drilling tool are provided, one mode is to directly clean the screw thread by using a high-pressure water gun, and the other mode is to manually clean the screw thread by using a rag and a steel wire brush. The former needs to use a high-pressure water gun, belongs to dangerous operation with pressure, electrification and water, and has certain danger, meanwhile, the water drops adhered to the screw thread and the screw thread oil are mixed to accelerate the deterioration of the screw thread oil and destroy the sealing and lubricating effects of the screw thread oil, so that the phenomenon of thread gluing of the screw thread is easily caused when the drilling tool is lifted out of a drill floor after the drilling tool works at high temperature and high pressure for a long time in the well, the torque is difficult to be removed, and further the operation time effectiveness and the drilling tool performance are influenced; the latter uses manual wiping, can't guarantee to clean stubborn impurity, if use the wire brush again the easy fish tail of fish tail damage screw thread terminal surface, make the screw thread sealing inefficacy. In view of the various drawbacks of the above two cleaning methods, there is an urgent need to develop a novel cleaning device for the thread of the drilling tool.

SUMMERY OF THE UTILITY MODEL

To the above-mentioned defect, the utility model aims at providing a clean effectual drilling rod box clearance ware.

The utility model provides a drill stem box cleaner, which comprises an insertion part arranged inside a box, wherein the insertion part is a conical body, a pipeline extending along the self axial direction is arranged inside the insertion part, one end of the pipeline is communicated with a cleaning medium source, and the other end of the pipeline is sealed; the insert comprises an insertion part and is characterized in that a plurality of rows of through holes are formed in the insertion part at intervals along the circumferential direction of the insertion part, each row of through holes are parallel to the axial direction of the insertion part, a sewage draining groove is formed between every two adjacent rows of through holes, the sewage draining groove is formed in the outer wall of the insertion part, one end of each through hole is communicated with a pipeline, and the other end of each through hole is communicated with the corresponding sewage draining groove.

Preferably, the cleaning medium source is a compressed gas line and/or a fresh water line.

Preferably, one end of the pipeline is communicated with a cleaning medium source sequentially through a connecting pipe and a ball valve.

Preferably, the insertion part is provided with three rows of through holes, and an included angle between two adjacent rows of through holes is 120 degrees.

Preferably, the number of the soil discharge grooves is three.

Preferably, the depth and the width of the sewage draining groove are both 20 mm.

The utility model discloses an useful part lies in:

1. the mixture of compressed air and water is adopted, the flushing force is appropriate, the effect is good, and the requirement of on-site screw thread cleaning is met; compared with the original washing mode, the washing device does not use high voltage and is uncharged, and the operation is safe and convenient; the inner wall of the female buckle cannot be damaged by hydraulic impact; after the hydraulic flushing is finished, the hydraulic flushing can be switched to air drying, so that the screw thread is cleaner, water drops adhered to the screw thread can be removed, subsequently applied screw thread oil is not polluted, and the sealing and lubricating performance of the screw thread oil is guaranteed;

2. the inserting part with a cone structure is adopted, so that the inserting part is convenient to insert into the female buckle, and sufficient clearance is provided for the flowing of impurities;

3. the whole device has simple structure and low manufacturing cost.

Detailed Description

The following describes the present invention in further detail with reference to the accompanying drawings. These embodiments are provided only for illustrating the present invention and are not intended to limit the present invention.

In the description of the present invention, it should be noted that the terms "inside", "outside", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, which are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In addition, in the description of the present invention, "a plurality" means two or more unless otherwise specified.

As shown in figure 1, the utility model provides a drilling rod box clearance ware, this clearance ware mainly including arrange the portion of inserting 4 that adopts the nylon plastics material to make in, the portion of inserting 4 is for matching and leaving the conical body in certain clearance with drilling rod box inner wall, and inside is equipped with along self axial extension's pipeline 43, pipeline 43 one end and cleaning medium source intercommunication, and the other end is sealed.
