The invention relates to a seismic data parallel storage system for storing seismic acquisition data, which is formed by two kinds of components, wherein one kind is processing components, the other kind is storage components, the processing components comprise a first-level storage engine, a second-level storage engine, a third-level storage engine and a storage scheduler; the storage componentscomprise a first-level storage component, a second-level storage component and third-level storage component; the first-level storage engine provides a memory interface to be connected with a seismicdata acquisition thread so as to wait for the arrival of seismic data; the second-level storage engine waits for the notice sent by the first-level engine; the third-level storage engine waits for the notice sent by the second-level storage engine; and the storage scheduler schedules the parallel storage process of the seismic data. The invention is produced aiming at the required characteristic of real-timely storing the seismic data, adopts multi-level buffer process and parallel storage data, and improves the data storage efficiency during the seismic data acquisition process on the basis of ensuring the reliability.
