The device for processing the inner blind hole of the perforating gun for the oil-gas well comprises a drilling tool assembly mounted on a cutting tool connecting rod, a supporting device and a vertical milling machine, wherein the drilling tool assembly is mainly composed of a sliding sleeve, a return spring and a drill bit mounted in the sliding sleeve; and the sliding sleeve is mounted in a sliding hole of the cutting tool connecting rod and supported on the return spring. During processing, a body of the perforating gun is clamped on a worktable of the vertical milling machine, and the body of the perforating gun can be moved by means of the worktable of the vertical milling machine, so that the drilling tool assembly and the supporting device extend into the body of the perforating gun, and then fixed supporting is formed through the supporting device; and a power transmission rod of the vertical milling machine penetrates through a pressure relief hole formed on the body of the perforating gun, and the power transmission rod of the vertical milling machine drives the drill bit of the drilling tool assembly to rotate to realize drilling feed until the processing of the inner blind hole is finished.
Description
Technical field
The utility model belongs to field of machining, relates in particular to the processing unit (plant) of oil gas well with blind hole in the perforating gun.
Background technology
At present; The oil gas well extensively adopts the body of a gun outer wall outer blind hole of processing with perforating gun or does not have the mode of blind hole; This just makes the height of burst of deep penetrating charge in the body of a gun low excessively, and much smaller than the desirable height of burst, the energy-gathering jetting that causes producing after the perforating bullet detonation meets with obstruction prematurely; Perforating bullet cumulative effect and energy performance are insufficient, thereby have reduced the penetration depth of perforator.According to the perforating bullet detonation theory, when the perforating bullet height of burst during less than the desirable height of burst, increasing the height of burst can significantly increase perforation and wear deeply.With outer blind hole or do not have the blind hole perforating gun and compare, be employed in that blind hole can increase the height of burst in the perforating bullet rifle, corresponding raising penetration depth in the processing of body of a gun inwall.Existing known in the processing of the body of a gun inwall blind hole mainly adopt two kinds of ways: (one) is through hole on body of a gun outer wall rig floor rank, selects identical materials to process sheet or gland then, and the process shutoff stepped hole part with welding or being pressed into causes interior blind hole.(2) designed a kind of overlength bar, utilized gear train or chain wheel set will cut power and be transmitted on the cutter that is fixed on the overlength bar other end, subsequently the feed motion through blind hole cutting in the motion realization of the body of a gun from an end of overlength bar; Tripartite planar defect below this method exists: no matter (1) takes gear train or chain wheel set to realize overlength bar transferring power, all inevitably has more serious power loss, causes power cost to increase; (2) chain gear transmission can't realize continuous transmission truly, and it is unstable, discontinuous to cause cutter to rotate, the quality of blind hole processing in the influence; Because gear train that the transmission instability causes or chain wheel set assembly frequent breakage are changed, cause the device service efficiency to reduce simultaneously; (3) receive the restriction of perforating gun internal diameter; The diameter of overlength bar is compared too small with length, when overlength bar and drilling tool were realized feed motion simultaneously, rigidity was not enough; Cause the predefined feeding depth and the degree of depth of actual processing bigger difference to occur, the quality of blind hole processing in having a strong impact on.
Summary of the invention
The utility model problem to be solved is: the processing unit (plant) of a kind of oil gas well with blind hole in the perforating gun is provided, and it need not directly to process interior blind hole at perforating gun body of a gun inwall through long apart from power transmission, and can guarantee the dimensional accuracy of interior blind hole.
