Seismic exploration system for petroleum exploration

Abstract

The invention relates to a seismic exploration system for petroleum exploration. The seismic exploration system comprises a remote monitoring terminal, controllable vibroseis and a plurality of wave detectors; the controllable vibroseis comprises a mobile device, an air pump, a transmission shaft and a vibroseis generating mechanism, the air pump and the transmission shaft are arranged under the mobile device in a vertically-downward mode, and the air pump is in transmission connection with the vibroseis generating mechanism through the transmission shaft. According to the seismic exploration system for petroleum exploration, the vibroseis generating mechanism is controlled by the air pump to rise and fall, the weight of the mobile device is completely added to a plate, and therefore the pressure weight of the controllable vibroseis is increased; meanwhile, vibration isolation can be conducted on ground force borne by the plate through a vibration isolation air spring, therefore, the plate is prevented from being decoupled, and the seismic exploration reliability is improved; furthermore, a reaction counterweight is balanced through two balance springs when the reaction counterweight generates angular deflection, the reliability that the reaction counterweight acts on the plate is guaranteed, and the seismic exploration reliability is further improved.

Description

Technical field [0001] The invention relates to a seismic exploration system for petroleum exploration. Background technique [0002] The so-called oil exploration is to find and identify oil and gas resources, and use various exploration methods to understand the underground geological conditions, understand the conditions of oil generation, oil storage, oil and gas migration, accumulation, and preservation, comprehensively evaluate the oil and gas prospects, and determine oil and gas. The process of finding the traps for oil and gas storage in the favorable areas of accumulation, and the area of ​​oil and gas fields, the process of clarifying the condition of oil and gas reservoirs and production capacity, and increasing crude oil reserves and related oil and gas products for the country. [0003] Before oil exploration, it is necessary to conduct seismic exploration in the oil field area to ensure the safety of future exploitation. In the existing seismic exploration system, th...

Problems solved by technology

In the existing seismic exploration system, the vibration wave emitted by the vibrator is detected by the geophone, but because the vibrator is in the working process, the plate will be decoupled, which will easily reduce the reliability of seismic exploration; Not only that, during the working process of the reaction weight, the action will not be in place due to the deviation of the reaction weight, which further reduces the reliability of seismic exploration
