Abstract
A skinner's macaroni for non-standard workover relates to drilling rod manufacturing technical field, specifically to a skinner's macaroni for small-diameter workover, and serves as a construction pipe string for workover in small-diameter bushing. The skinner's macaroni for non-standard workover comprises a bushing body, and a male joint and a female joint connected on both ends of the bushing body respectively, wherein external threads are arranged on the male joint, internal threads are arranged on the female joint, the tooth section of the external threads is of a trapezoid shape, the lower base of the trapezoid is connected to the male joint, one leg of the trapezoid is at a 95 degree angle to the upper base of the trapezoid, the other leg of the trapezoid is at a 115 degree angle to the upper base of the trapezoid, the tooth section of the internal threads is of a trapezoid shape, the upper base of the trapezoid is connected to the female joint, one leg of the trapezoid is at a 95 degree angle to the lower base of the trapezoid, and the other leg of the trapezoid is at a 115 degree angle to the lower base of the trapezoid. The skinner's macaroni for non-standard workover is strong in tension and anti-torsion strength, and can prevent occurrence of underground disasters.
Description
Technical field
The utility model relates to a kind of manufacturing technology field of drilling rod, and particularly a kind of minor diameter Drilling rod for well-drilling should be as the operating tool string of workover treatment in the minor diameter sleeve pipe.
Background technology
At present in the oil well repairing operation, Drilling rod for well-drilling mainly adopts the geologic drilling rod of Φ 50mm in the following minor diameter sleeve pipe of Φ 85mm, joint is Φ 68mm, adopt 2 " the geology button-type, tension, the torsional strength of this tool joint are less, in daily workover treatment process; the drill rod breaking phenomenon often occurs; cause overhaul construction failure, seriously may cause down-hole accident, oil well is scrapped; And the method that improves drilling rod intensity is exactly the external diameter that increases body, adopt the standard Φ 60mm drilling rod of big one-level, but it is also infeasible directly to use the big drilling rod of conventional Φ 60mm, this mainly is because Φ 60mm tool joint external diameter is Φ 86mm, does not go down in internal diameter is Φ 82mm, Φ 76mm minor diameter sleeve pipe commonly used.
The utility model content
In order to solve existing minor diameter Drilling rod for well-drilling tension, the less shortcoming of torsional strength, the utility model provides a kind of nonstandard well workover macaroni.
The utility model comprises body, at described body two ends male joint and female joint are set respectively, in described male joint, external screw thread is set, in described female joint, internal thread is set, described externally threaded profile of tooth section is trapezoidal, described trapezoidal going to the bottom is connected in the male joint, angle between a described trapezoidal waist and the upper base is 95 °, described another trapezoidal waist and the angle between the upper base are 115 °, the profile of tooth section of described internal thread is trapezoidal, described trapezoidal upper base is connected in the female joint, a described trapezoidal waist and go to the bottom between angle be 95 °, described trapezoidal another waist and go to the bottom between angle be 115 °.
The utility model is arranged to thread trapezoidal, angle between a trapezoidal waist and the upper base is 95 °, another waist and go to the bottom between angle be 115 °, this non-standard button-type becomes the D33 button-type, this button-type tension, torsional strength are big, have avoided the generation of down-hole accident.
The external diameter of male joint of the present utility model is 71mm, and internal diameter is 32mm, and the thick section external diameter is 61mm; The external diameter of female joint is 71mm, and internal diameter is 32mm, and the thick section external diameter is 61mm.This set has been avoided the phenomenon of not going down in internal diameter is the sleeve pipe commonly used of Φ 82mm, Φ 76mm.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is the A portion enlarged drawing of Fig. 1;
Fig. 3 is the B portion enlarged drawing of Fig. 1.
Among the figure, 1, body, 2, male joint, 3, female joint, 4, external screw thread, 5, internal thread, 6, trapezoidal, 7, trapezoidal, 8, the thick section.
The specific embodiment
As Fig. 1,2, shown in 3, comprise body 1, at body 1 two ends male joint 2 and female joint 3 are set respectively, external screw thread 4 is set in male joint 2, internal thread 5 is set in female joint 3, the profile of tooth section of external screw thread 4 is trapezoidal 6, trapezoidal 6 go to the bottom is connected in the male joint 2, trapezoidal 6 waist and the angle between the upper base are 95 °, trapezoidal 6 another waist and the angle between the upper base are 115 °, and the profile of tooth section of internal thread 5 is trapezoidal 7, and trapezoidal 7 upper base is connected in the female joint 3, a waist of trapezoidal 7 and go to the bottom between angle be 95 °, another waist of trapezoidal 7 and go to the bottom between angle be 115 °; The external diameter of male joint 2 is 71mm, and internal diameter is 32mm, and thick section 8 external diameters are 61mm; The external diameter of female joint 3 is 71mm, and internal diameter is 32mm, and thick section 8 external diameters are 61mm.
Claims (3)
1. nonstandard well workover macaroni, comprise body, at described body two ends male joint and female joint are set respectively, in described male joint, external screw thread is set, in described female joint, internal thread is set, it is characterized in that described externally threaded profile of tooth section is trapezoidal, described trapezoidal going to the bottom is connected in the male joint, angle between a described trapezoidal waist and the upper base is 95 °, described another trapezoidal waist and the angle between the upper base are 115 °, the profile of tooth section of described internal thread is trapezoidal, described trapezoidal upper base is connected in the female joint, a described trapezoidal waist and go to the bottom between angle be 95 °, described trapezoidal another waist and go to the bottom between angle be 115 °.
