Movable downhole vibroseis device and its control system

Abstract

The invention discloses a movable underground vibrator device and its control system. The device includes a mobile crawler car body, a power storage device, a vibration mechanism and an adjustment device. The vibration mechanism is movably arranged on the movable crawler through a pivot On the car body, the adjustment device is arranged on the mobile crawler car body, and can push the vibration mechanism to turn over; The vibration mechanism makes a tamping action; the structure design of the present invention is ingenious and reasonable, the working stability is good, the mobility is strong, and it is convenient for transportation and movement in the underground environment, and the tamping effect is excellent, and at the same time, different vibrations can be changed through the adjustment device. The ramming position meets the ramming requirements of different positions and has a wide range of applications. In addition, the control system provided by the invention is simple, easy to implement, simple to operate, saves time and effort, greatly improves work efficiency, and is conducive to wide application.

Description

technical field [0001] The invention relates to the technical field of geological exploration, in particular to a movable downhole vibroseis device and a system thereof. Background technique [0002] Seismic exploration is an important means of geological exploration. Seismic exploration needs to artificially stimulate seismic waves, collect and analyze the reflected waves during the transmission of seismic waves in the formation, and use various parameters of the excited seismic waves to jointly analyze and deduce the structure and properties of the formation. At present, explosives are mainly used as the excitation source in coalfield geological exploration, but due to the destructiveness of the explosion source and the non-repeatability of the signal, people began to use the vibroseis with precise control of the excitation waveform and high efficiency as the main source of geological exploration. Activate the device. [0003] The invention patent with the application nu...

Problems solved by technology

[0003] The invention patent with the application number 201310491942.X discloses a vibrator vibrator and system, which is mainly used in ground oil detection. The tonnage of the vibrator is relatively large, and it can only be excited vertically downwards, which is not suitable for small underground spaces. However, some other equipment that use pneumatic cylinders or hydraulic cylinders for tamping, although simple in structure, have very little tamping energy because they do not have too much counterweight, and downhole hydraulic or pneumatic energy is not available everywhere. application
