Single Controllable Vibrator High-Density Acquisition Technology and Its Application

Abstract

Abstract: The acquired seismic data are required to have high signal-to-noise ratio and resolution because the domestic exploration areas have large surface fluctuations, small deployment area, large buried depth of target layer, and thin layer. Based on the characteristics that the signal excited from the controllable vibrator is controllable, the research and test is conducted on single onshore controllable vibrator high-density acquisition. Meanwhile, it is also the first block for field test of low frequency multi-channel onshore seismic acquisition system. Based on the test results, this technology can effectively solve the problem that the channel capacity of present instruments and peripheral equipment are inadequate. Industrialized production by means of single controllable vibrator high-density acquisition is carried out for the first time at home. Meanwhile, this technology helps complete 3D seismic acquisition work in a number of blocks, achieving good geological results.

Key words: controllable vibrator, single excitation, high-density, acquisition technology, results
