Embodiment Construction

[0010] The specific implementation of the present invention will be further described below in conjunction with the examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0011] The technical scheme of concrete implementation of the present invention is:

[0012] A concentric helical drilling tool, comprising a drilling tool main body, the drilling tool main body is coated with a protective layer, and the protective layer is produced through the following steps:

[0013] 1) Take 5.7 parts of modified polybutadiene resin, 2.3 parts of ethylene bis stearamide, 0.5 parts of titanium dioxide, 1.1 parts of alumina, 1.3 parts of benzyl alcohol, 1.3 parts of 3-chloro-2-carboxypropyl tris Methyl ammonium chloride is fully stirred evenly to obtain the bottom protective coating;

[0014] 2) Take 6.7 parts of polyurethane resin, 1.6 parts of methyl metha...

Abstract

The invention discloses a concentric pipe-following drilling tool. The concentric pipe-following drilling tool comprises a drilling tool body. The drilling tool body is coated with a protective layer. A preparing method of the protective layer includes the following steps that 1, 5.7 parts of modified polybutadiene resin, 2.3 parts of ethylene distearamide. 0.5 part of titanium dioxide, 1.1 parts of aluminum oxide, 1.3 parts of phenylcarbinol, 1.3 parts of 3-chloro-2-hydroxypropyltrimethylammonium chloride are taken and sufficiently stirred to be even, and a bottom-layer protective coating is obtained; 2, 6.7 parts of polyamino resin, 1.6 parts of methyl methacrylate, 1.2 parts of vinyl trimethoxy silane, 0.9 part of castor oil, 0.4 part of silicon dioxide and 1.2 parts of lime powder are taken and sufficiently stirred to be even, and a face-layer protective coating is obtained; 3, the bottom-layer protective coating is sprayed to the surface of the drilling tool body, cured and dried; 4, then the face-layer protective coating is sprayed, cured and dried. According to the concentric pipe-following drilling tool, the drilling tool body is coated with the protective layer, and the service life of the concentric pipe-following drilling tool can be prolonged.

Description

technical field [0001] The invention relates to a concentric follower pipe drilling tool. Background technique [0002] The working environment of the existing concentric tubular drilling tools is generally harsh and needs to work for a long time, so it needs to be effectively protected. Contents of the invention [0003] The object of the present invention is to provide a concentric heel pipe drilling tool, the main body of the drilling tool is coated with a protective layer, so that the main body of the drilling tool has the performance of wear resistance, corrosion resistance and heat insulation, and can improve the service life of the concentric heel pipe drilling tool . [0004] In order to achieve the above object, the technical solution of the present invention is to design a concentric helical drilling tool, including a drilling tool body, the drilling tool body is coated with a protective layer, and the protective layer is obtained through the following steps: ...
