Abstract：With the advance in both field equipment and seismic technology,significant progress of HD(high density) seismic acquisition has been made in recent years.In 2008,Shengli Oil Field of Sinopec has conducted a land HD seismic acquisition in Luojia area.This was the first HD acquisition with over 10,000 live channels of 3C digital sensors in China.We adopted single-receiving technique that means that a single 3C sensor was planted at each receiver point.Based on noise characteristics analysis in the working area,a centralized swath orthogonal symmetric geometry was used.This geometry improves continuity and uniformity of seismic events.Many methods were used to investigate near surface structures.Some minor near surface structure models were built.In field acquisition,receiver coupling was improved and data quality control was monitored by on-site processing.So high quality 3C data were acquired.At the same time,an efficient field operation procedure for large-live-channel-count survey was developed.
