Mud Gun Vibration Source Gun Drill Integrated Drilling Type Gun Lowering Mechanism

Abstract

The invention discloses a mud gun vibrating source gun drill integrated drilling type gun lowering mechanism, which includes a lower drill rod, and a mud gun is sleeved in the inner cavity of the lower drill rod, and the mud gun and the lower drill rod form an integrated structure. A mud gun nozzle is provided on the side wall of the lower part of the mud gun, and a high-pressure air nozzle is provided on the bottom side wall of the lower drill pipe. The upper drill rod is also included. The upper drill pipe and the lower drill pipe are provided with a spiral air gun cable, and the upper end of the air gun cable extends out of the upper drill pipe and is connected with an electrical slip ring. The inner wall of the lower drill pipe is provided with a wear-resistant and anti-collision lining, and the mud gun is closely fitted inside the wear-resistant and anti-collision lining. The upper drill rod and the lower drill rod are quickly connected with lock pins. The invention is applicable to the lowering mechanism of the mud gun under the medium conditions of mud, hard sand board and sandstone hard surface, covers all the surface structures of the mud gun operation, has an integrated gun drill, and has high operating efficiency.

Description

Technical field [0001] The invention relates to an excitation technology for beach and shallow sea petroleum geophysical exploration, in particular to a mud gun seismic source gun drill integrated drilling down gun mechanism used in the excitation link of beach and shallow sea seismic exploration. Background technique [0002] Mud gun seismic source is a kind of acoustic energy source used for shoal and shallow sea oil geophysical exploration. The lower gun mechanism of traditional mud gun seismic source adopts the downward pressure type, which is only suitable for mud surface, simple process and narrow application range. For hard sand board and Sandstone hard surface media cannot be used. Summary of the invention [0003] The purpose of the present invention is to provide a mud gun seismic source gun drill integrated drilling type lower gun mechanism, which is suitable for mud, hard sand and sandstone hard surface medium conditions, and covers all surface structures for mud gun o...
