Mud gun source gun drill integrated drilling mechanism

Abstract

The present invention provides a mud gun source gun drill integrated drilling mechanism. The mud gun source gun drill integrated drilling mechanism comprises a lower drilling rod, a mud gun sleeves on an inner cavity of the lower drilling rod, and the mud gun and the lower drilling rod form an integrated structure. The side wall at the lower part of the mud gun is equipped with a mud gun nozzle, the bottom side wall of the lower drilling rod is equipped with a high pressure air nozzle, the mud gun nozzle and the high pressure air nozzle correspond to and are overlapped with each other, and the bottom end of the lower drilling rod is connected with a drill. The mud gun source gun drill integrated drilling mechanism also comprises an upper drilling rod, the upper and lower drilling rods are equipped with spiral gas gun cables, and the upper ends of the gas gun cable are extended out of the upper drilling rods to be connected with electrical slip rings. The inner wall of the lower drilling rod is equipped with a wear resistant anti-collision liner, the mud gun matches the wear resistant anti-collision liner tightly, and the upper and lower drilling rods are in locking pin type rapid connection. The mud gun source gun drill integrated drilling mechanism of the present invention is suitable for the mud gun drilling mechanism on the mud, hard sand plate and sandstone hard surface medium conditions, covers the all surface structures of the mud gun works, is gun drill integrated, and is high in working efficiency.

Description

technical field [0001] The invention relates to an excitation technology for shallow sea petroleum geophysical exploration, in particular to a mud gun source gun drill integrated drilling type gun lowering mechanism used for the excitation link of shallow sea seismic exploration. Background technique [0002] The mud gun source is an acoustic energy source used for shallow sea petroleum geophysical exploration. The gun lowering mechanism of the traditional mud gun source adopts a downward pressure type, which is only suitable for muddy surfaces. The process is simple and the application range is narrow. It is suitable for hard sand boards and Sandstone hard surface media cannot be used. Contents of the invention [0003] The object of the present invention is to provide a mud gun vibrating source gun drill integrated drilling type gun lowering mechanism, which is suitable for the mud gun lowering mechanism under the conditions of mud, hard sand board and sandstone hard sur...
