Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used to limit scope of the present utility model.
Embodiment one
As shown in Figure 1, the utility model provides blind hole perforating gun in a kind of two-layer compound tubing, comprising: inner layer pipe 2 and outer tube 1;
Outer tube 1 is enclosed within the external surface of inner layer pipe 2, and described outer tube 1 and inner layer pipe 2 are made up of steel; The steel strength of outer tube 1 equals the steel strength of described inner layer pipe 2;
Inner layer pipe 2 is provided with interior blind hole 3.
Wherein, outer tube 1 and inner layer pipe 2 adopt finish-rolling process to be shaped separately, and be combined into one by thermoforming process, described outer tube both ends jumping-up, encases the end of inner layer pipe.
Wherein, the steel strength of described outer tube equals the steel strength of described inner layer pipe, and described outer tube steel and inner layer pipe steel strength reach the 150-110 grade of steel of API standard.
The perforating gun that the utility model provides adopts the double-decker of inner layer pipe and outer tube, inner layer pipe Absorbable rod detonation wave, outer tube plays support and high voltage bearing effect, perforation rear lance is swollen less, reduces the possibility that card well accident occurs because the body of a gun swells; In addition, directly blind hole is set in inner layer pipe, greatly improves working (machining) efficiency, and product processing quality and dimensional accuracy are ensured.
Embodiment two
The utility model provides blind hole perforating gun in a kind of two-layer compound tubing, comprising: inner layer pipe 2 and outer tube 1;
Outer tube 1 is enclosed within the external surface of inner layer pipe 2, and described outer tube 1 and inner layer pipe 2 are made up of steel; The steel strength of outer tube 1 is greater than the steel strength of described inner layer pipe 2;
Inner layer pipe 2 is provided with interior blind hole 3.
Wherein, outer tube 1 and inner layer pipe 2 adopt finish-rolling process to be shaped separately, and be combined into one by thermoforming process, described outer tube both ends jumping-up, encases the end of inner layer pipe.
