Abstract

The invention discloses a split type mud gun vibrating source drilling tool, and belongs to the technical field of drilling. A main shell is cylindrical, a half of one end of the main shell is cut, a check ring is welded to a notch of an inner cavity of the main shell, a transition sleeve is fixedly welded to the upper end of the main shell, and an upper flange is fixedly welded to the upper end of the transition sleeve so that the upper end of the transition sleeve can be connected with a drill rod. A drill bit flange is fixedly welded to the outer circle of the lowest end of the main shell, the lower end face of the drill bit flange is flush with the lower end face of the main shell, and angle ribs are welded between the drill bit flange and the main shell. A screw blade with a half lead is fixedly welded to the lower side of a square hole of the outer circle of the main shell, the lead of the screw blade is 800 mm, and the external diameter phi of the screw blade is 600 mm. A semi-circular-ring-shaped upper connecting tile is fixedly welded to the lower side of the check ring of the inner cavity of the main shell, a bolt connecting hole is machined in the upper connecting tile, a semi-circular-ring-shaped filling body is fixedly welded to the lower side of the upper connecting tile, and square holes are machined in the positions, corresponding to air vents of a mud gun, of the filling body and the main shell. A lower connecting tile is welded to the inner cavity of the lowest side of the main shell.

Description

technical field [0001] The invention relates to a split-type mud gun seismic source drilling tool, which belongs to the technical field of drilling. Background technique [0002] At present, oil exploration equipment mainly includes vibrators (used for relatively flat land), explosives, and air gun sources (used in areas with a water depth greater than 3m), but in land-water interactive zones and swampy areas, ships cannot travel due to vibrators and air gun sources. , only explosives can be used, which has poor environmental protection, high construction costs, and potential safety hazards. In some areas, local governments or oil companies do not allow the use of explosives. Foreign air gun manufacturers have developed mud guns that can be excited in mud, but they have not been successfully applied. There are domestic and foreign related companies conducting research on the application of air guns and mud guns, but they mainly use mechanical pressing, which limits the exci...
