A seismic data processing method and device

Abstract

An embodiment of the invention discloses a method and a device for processing seismic data. The method comprises the following steps: collecting single-channel seismic data and generating shot gather record in the seismic data; determining a master node and a slave node from preset nodes and preprocessing the gather record seismic data on the master node; building output data index on the preprocessed gather record seismic data on the master node to generate a first file which comprises an accumulator for distributing data and counted number; sending the shot gather record information and the first file to the slave node; counting the number of target nodes via the master node for distributing task to the target nodes; acquiring target data by the target nodes according to the output data index after obtaining the task, processing the target data and storing the processed data according to the output data index. Through the method and the device for processing the seismic data, the seismic data processing efficiency can be improved.

Description

technical field [0001] The present application relates to the technical field of geophysical exploration, in particular to a seismic data processing method and device. Background technique [0002] With the continuous development of oil exploration technology, in geophysical seismic data processing technology, the demand for new geophysical prospecting methods and technologies is getting higher and higher. Such geophysical prospecting methods and technologies such as wave field continuation datum correction require efficient computer computing power support. [0003] For the field of geophysical exploration technology, the use of computer parallel technology is still a relatively cutting-edge technology. It is different from other fields that require parallel computing in many aspects. The most important point is that the seismic data processing has a huge amount of data. Different computers are faced with a large data and information exchange. Only by relying on the devel...

Problems solved by technology

[0005] The inventors found that there are at least the following problems in the prior art: the existing parallel method needs to read all the seismic data that needs to be extended, and send these data to each slave node, and the seismic data after each slave node completes the wave field continuation Send back to the master node, the master node writes the data to the disk after receiving the data, because the computing power of the slave node is often different, so the slave node often needs to wait, wait for the master node to complete the corresponding task before receiving the next earthquake sent back from the slave node data

Therefore, the existing seismic data processing methods will spend too much parallel computing time, seriously affecting the efficiency of parallel computing
