EFFICIENT SEISMIC FILE TRANSMISSION

摘要

Methods, systems, and devices for conducting a seismic survey. The system includes a seismic sensor supplying a seismic signal; sampling circuitry configured to convert the signal to a sequence of samples, each sample represented by a bit string; a data communication device configured to transmit compressed seismic data; a recording computer configured to receive compressed seismic data; at least one processor with a computer memory accessible thereto, the at least one processor configured to: create a sample block by storing at least a portion of the sequence of samples in memory units in the computer memory, wherein each sample is stored in a corresponding memory unit; and compress data contained in the sample block by encoding all bits of a particular bit number from the memory units of the sample block in sequence to produce compressed seismic data.

1. A system for conducting a seismic survey, comprising:
at least one seismic sensor configured to supply a signal responsive to reflections of acoustic energy from an earth surface; sampling circuitry in electrical communication with the at least one seismic sensor and configured to convert the signal to a sequence of samples, wherein each sample is represented by a bit string; and at least one processor and a computer memory accessible to the at least one processor, the at least one processor configured to:
create a sample block by storing at least a portion of the sequence of samples in memory units in the computer memory, wherein each sample is stored in a corresponding memory unit; andcompress data contained in the sample block by encoding all bits of a particular bit number from the memory units of the sample block in sequence to produce compressed seismic data; a data communication device configured to transmit the compressed seismic data; and a recording computer configured to receive the compressed seismic data.
