Equipment for correlated processing of vibroseis data in GPU/CPU coordinated mode and method thereof

Abstract

The invention relates to equipment for correlated processing of vibroseis data in a graphics processing unit (GPU) / central processing unit (CPU) coordinated mode and a method thereof, so that problems of a complicated structure and poor reliability in the prior art can be solved. The equipment is composed of six major units: a memory or an internal memory, a memory device, a GPU, a CPU, a terminal and a field data collection interface. The field data collection interface that is connected with a field component by a gigabit optical cable so as to collect seismic field data; connection between the field data collection interface and the CPU is provided by two bound gigabit network cables; the GPU, the memory and the memory device are connected by a high speed interface on a mainboard of the CPU; and the terminal equipment is also connected on the CPU mainboard. According to the invention, processing like correlation can be carried out rapidly on an original vibroseis record; besides the equipment has advantages of simple structures of correlated technical components of vibroseis, improved reliability, substantial reduction of cost, significant improvement on data processing capability, corresponding improvement of the system upgrade capability as well as substantial enhancement of real-time tape track capability and collection efficiency of a seismic apparatus.

Description

Technical field [0001] The invention relates to a seismic exploration data preprocessing method, in particular to a GPU / CPU coordination mode controllable seismic source data related processing equipment and method. technical background [0002] 1. The development status of controllable seismic source acquisition technology and related requirements for seismic exploration instruments [0003] With the development of seismic exploration technology and the increasing requirements for environmental protection, controllable seismic sources are used more and more widely in seismic exploration. However, compared with impulse resources, the use of controllable seismic sources often means a great increase in the time of field operations. In order to meet the requirements of sampling as high as possible and reduce the exploration cost at the same time, it is necessary to increase the collection efficiency of the controllable seismic source as much as possible and shorten the field operation...

[0004] 2. Current status of correlative processing of vibrator data of commonly used seismographs

The longer the acquisition time, the more channels, and the denser the sampling points, the more data needs to be processed. In the case that the processing and recording speed cannot be solved better, the only way to continue to extend the interval between two vibrations is to slow down construction efficiency
