Abstract：Taking the project of vibroseis' high-resolution seismic acquisition in Mozambique in 2005 as a case,the paper introduced the construction approaches and quality assurance measures.The construction approaches included several links such as environment noise tests,and determination of basic parameters and source parameters among which the determination of source parameters was key link.In view of the difference of geologic conditions on the surface in the western,northern and eastern parts of working zone,the paper implemented detailed experiments at points and on segments,determining such source parameters as sweep frequency, length,number of times, drive amplitude, slope value of sweep signal and preamplifier gain of seismograph.The quality assurance measures included two links: indoor and field, the field link was important one among the two,including actual some aspects such as measurement point by point for receiver and shot points,guaranteeing the receiving quality of geophone,reducing coherent interference of source and enforcing on-site QC of seismograph.The approaches in the paper can provide some references to vibroseis' high-resolution exploration at home.
