Summary of the invention
The purpose of this utility model is to provide the nonstandard drilling tool of a kind of numeric type bindiny mechanism, it mainly solves in the existing API standard, the product size that numeral rotation shoulder connects is the 5.0417 inches blank of leaping to 5.616 inches in middle footpath in footpath therefrom, it has well improved the hydraulic performance of tool joint, and making drilling tool connect has good use value in practice.
The utility model solves the problems of the technologies described above the technical scheme that is adopted.
The nonstandard drilling tool of a kind of numeric type bindiny mechanism, it is made up of male connection and female adapter, it is characterized in that: the pitch diameter of thread of this internal and external screw thread joint at the reference plane place is 5.39 inches, it is 1:6 that tooth form adopts tapering, the API V-0.038R numeric type connecting thread tooth form of 4 tooth/inches.
The nonstandard drilling tool of described numeric type bindiny mechanism, it is characterized in that: this internal and external screw thread joint external diameter OD is 7.25 inches, inner diameter, ID is 3 inches, the connection length L pc of male connection is 4.5 inches, the cylinder root diameter (RD) Dlf of male connection is 5.485 inches, it is 4.625 inches that the minimum of female adapter connects length L bt, and bore diameter Qc is 5.66 inches, and the shoulder bevel diameter Df of internal and external screw thread joint is 6.928 inches.
The nonstandard drilling tool of described numeric type bindiny mechanism, it is characterized in that: this internal and external screw thread joint external diameter OD is 6.625 inches, inner diameter, ID is 3.75 inches, the connection length L pc of male connection is 4.5 inches, and the cylinder root diameter (RD) Dlf of male connection is 5.485 inches, it is 4.625 inches that the minimum of female adapter connects length L bt, and bore diameter Qc is 5.66 inches, and the shoulder bevel diameter Df of internal and external screw thread joint is 6.45 inches.
The beneficial effects of the utility model are: all adopting tapering on the internal and external screw thread joint of the present utility model is 1:6, the API V-0.038R form of thread of 4 tooth/inches, the pitch diameter of thread at the reference plane place is 5.39 inches, it has remedied in the API standard, the product size that numeral rotation shoulder connects is the 5.0417 inches blank of leaping to 5.616 inches in middle footpath in footpath therefrom, well improved the hydraulic performance of tool joint, making the utility model drilling tool connect has good use value in practice.
Description of drawings
Fig. 1 is a structure chart of the present utility model.
The specific embodiment
Below please in conjunction with the accompanying drawings 1 and specific embodiment further introduce the utility model.
Embodiment 1.
The specific embodiment 1 of the nonstandard drilling tool of the utility model numeric type bindiny mechanism is, at external diameter OD is 7.25 inches, inner diameter, ID is (comprising female adapter and male connection) on 3 inches the tool joint, male connection, the female adapter of processing the nonstandard drilling tool of numeric type described in the utility model.The form of thread of joint is API V-0.038R, and the tapering of connection is 1:6, and pitch is 4 tooth/inches.The pitch diameter of thread of male connection at the reference plane place is 5.39 inches, and the connection length L pc of male connection is 4.5 inches, and the cylinder root diameter (RD) Dlf of male connection is 5.485 inches.The pitch diameter of thread of female adapter at the reference plane place is 5.39 inches, and it is 4.625 inches that the minimum of female adapter connects length L bt, and bore diameter Qc is 5.66 inches, and the shoulder bevel diameter Df of internal and external screw thread joint is 6.928 inches.
In identical under the situation of external diameter, external diameter is 7.25 inches, and internal diameter is 3 inches, and the torsional strength of the nonstandard tool joint of present embodiment numeric type is 83000ft*lb, the torsional strength of 5 1/2FH tool joints is 78700ft*lb, and the present embodiment joint is higher by 6% than 5 1/2FH joint torsional strengths.Under identical torsional strength, adopt the external diameter of the utility model structure can be reduced to 7 inches, the pressure consumption of mud in annular space when helping reducing drilling well like this, this is of practical significance concerning drilling very much.In addition, adopt numeric type to connect, than adopting the FH full hole to connect, the stress of drilling tool is concentrated obviously and is reduced, and has prolonged the application life of drilling tool.
Embodiment 2.
The specific embodiment 2 of the nonstandard drilling tool of the utility model numeric type bindiny mechanism is, at external diameter OD is 6.625 inches, inner diameter, ID is on 3.75 inches the tool joint (comprising female adapter and male connection), external thread structure, the female adapter of processing the nonstandard drilling tool of numeric type described in the utility model.The form of thread of joint is API V-0.038R, and the tapering of connection is 1:6, and pitch is 4 tooth/inches.The pitch diameter of thread of male connection at the reference plane place is 5.39 inches, and the connection length L pc of male connection is 4.5 inches, and the cylinder root diameter (RD) Dlf of male connection is 5.485 inches.The pitch diameter of thread of female adapter at the reference plane place is 5.39 inches, and it is 4.625 inches that the minimum of female adapter connects length L bt, and bore diameter Qc is 5.66 inches, and the shoulder bevel diameter Df of internal and external screw thread joint is 6.45 inches.
