Field arrangement management base station and method of wired telemetry seismograph

Abstract

The invention discloses a field arrangement management base station and method of a wired telemetry seismograph, and belongs to the technical field of seismic data acquisition of exploration and development of the petroleum resource, the natural gas resource and the coal resource. A seismograph mainframe system is connected with a third field arrangement management base station through a second cable and connected with a fourth field arrangement management base station through a third optical cable, the third field arrangement management base station is connected with a second field management base station through a first cable, the second field arrangement management base station is connected with a first field arrangement management base station, the fourth field arrangement management base station is connected with a fifth field arrangement management base station, and the fifth field arrangement management base station is connected with a sixth field arrangement management base station, and one end of the first field arrangement management base station is connected with a sixth acquisition station and a first acquisition station. A data relating and overlapping function, a quality control analysis function and other data processing functions of a central recording unit of a current mainstream wired telemetry seismograph are distributed into the field arrangement management base stations, and the data processing burdens of the central recording unit are greatly relieved.

Description

technical field [0001] The invention relates to a field arrangement management base station and a method of a wired telemetry seismograph, and belongs to the technical field of seismic data acquisition for exploration and development of oil, natural gas and coal resources. Background technique [0002] At present, all mainstream wired telemetry seismometers, whether it is the 400 series of the French SERCEL company, the Uniq system of the American WesternGeco company, or the G3i instrument of the INOVA company of Dongfang Geophysical Prospecting Holdings, all send the data collected in the field to the central recording unit. (located in the instrument cabin) to centrally perform various processes such as calibration, arrangement, denoising, correlation, superposition, quality control analysis, etc., which makes the performance of the instrument host always appear to be stretched, and it always appears that it cannot meet the massive data. High-speed, real-time processing ne...

Problems solved by technology

The number of receiving channels in the field has expanded from the current thousands to tens of thousands, hundreds of thousands, and millions of channels in the future, and the data volume of a single shot has also increased from the current tens of megabytes to hundreds of megabytes, gigabytes, The development of 10-gigabit bytes has made it impossible to break through the bottleneck of expanding the channel capacity of the acquisition system simply by improving the hardware performance and data processing capabilities of the central recording unit. This is mainly due to the overall development of electronic manufacturing technology at the current stage. The level is not enough to launch a small computer system that can perform real-time complex calculation processing on such a large amount of data and is easy to move in the field
