Abstract

The invention relates to an intra-tube release type pneumatic controllable-source vibrator and belongs to the field of oil and gas exploration. The intra-tube release-type pneumatic controllable-source vibrator comprises a bottom anvil part, an impact hammerhead, a base table, a rectangular bearing plate, an intra-tube release, a cylinder, a supporting hydraulic cylinder, a pillar, an upper mounting plate, a hanging part, a guide post and a lifting hydraulic cylinder; a piston rod of the lifting hydraulic cylinder is provided with a central through hole; the part, close to the lower surface of a piston, of the piston rod is provided with at least one radial through hole; the central through hole is communicated with the radial through holes; one the side, close to the upper surface of the piston, of the piston rod, the central through hole is closed by means of a plug or by means of welding; the intra-tube release is in threaded connection with the tail end of a piston rod of the lifting hydraulic cylinder and is disposed within the cylinder; the part, fitting a fishing head at the end of the piston rod of the cylinder, of a clamping head of the intra-tube release is provided with a slope; the intra-tube release clamps the piston rod of the cylinder through oil supply by the central through hole of the piston rod of the lifting hydraulic cylinder. The intra-tube release type pneumatic controllable-source vibrator has the advantages that rated output is high, system pressure is low, locking synchronism is high, and each connection is in a locking structure, ensuring good locking performance.

Description

technical field [0001] The invention belongs to the field of seismic exploration, in particular to an in-pipe hands-off pneumatic vibrator for simulating seismic waves. [0002] Background technique: [0003] Seismic exploration is to transmit an excitation signal to the formation through artificial excitation, then observe and analyze the received formation reflection signal, and then infer the structure and properties of the formation, and explain the possibility of the existence of mineral deposits. Since Bill Doty, a geophysicist from the American Petroleum Corporation, and his mentor John Crawford proposed the theory of vibrator based on radar and sonar echo ranging technology in 1952, vibrator technology has continued to develop. Because of its safety, environmental protection, and economical features, vibrators are more and more widely used in land and ocean seismic exploration. [0004] Although the application range of vibrator technology is becoming more and more e...
