Innovative integration of the 60000-channel acquisition technique for 3D data acquisition in Well Ma-131 Block

Abstract

Abstract: Areas around Mahu in the Junggar Basin contain abundant hydrocarbons, suggesting great potentials for exploration. However, low SNRs and resolutions of available seismic data for these areas negatively affect discovery of high-quality reservoirs, verification of lithologic traps and detection of hydrocarbons. In order to address these deficiencies, integration of various sophisticated acquisition techniques was considered for 3D seismic data acquisition in Well Ma-131 Block. By way of simultaneous tests and practical operations, the integration of techniques helped to address the technical problems in remote data transmission, widening of data frequencies, enhancement of data acquisition efficiency, real-time quality control and others. Eventually, the integration solution is successfully promoted and applied in Well Ma-131 Block and other areas, with quality of seismic data improved significantly.

Key words: 60000-channel acquisition, controllable seismic sources, real-time quality control, synchronous slip scanning, Junggar Basin, Well Ma-131 Block
