With the continuous advancement of seismic exploration and an expansion in the range of human activities,areas of exploration and associated surfaces have become increasingly complex to negotiate when acquiring seismic data.In addition,areas of exploration have now been expanded to urban areas,oil areas,pipelines,and other places where there are a variety of obstacles,which results in the need for complex seismic operational methods,and involves greater operational difficulty and lower work efficiency.During seismic data acquisition of complex transition zone (TZ),the obstacles are usually numerous,and the work area often contains intricate pipelines,wells,power grids,buildings,and areas under nature protection.In addition,mixed excitation methods are required,such as vibroseis,explosives,and different kinds of air guns.With the continuous increase in awareness of seismic operational safety and environmental protection,the valid acquisition area of seismic projects has become increasingly narrow,and the range of source point deployment has increasingly reduced.These factors are leading to the acquisition of poor quality seismic data,and even data gaps in some areas.There is an urgent need to determine effective acquisition space to reasonably lay out source points.Optimization of geometry,and excitation and receiving parameters improve seismic data quality,and although the use of data interpolation can compensate for missing data during later processing it is associated with "false" suspects.During actual operations,safe distance values are usually provided by clients or determined using instrument tests.However,safety distances are generally too large,and thus the effective acquisition space is greatly compressed.Based on above two points,this paper uses Sadov's vibration formula,known in engineering blasting,for seismic exploration,and combines flexibility of testing instruments and scientifically calibrated safety distances,thereby improving the capacity of the source layout,which further expands the seismic acquisition space,improves the quality of seismic data,ensures the safety of operations,and enhances the operation schedule.The research provided in this paper is thus of considerable use for seismic exploration in complex areas.
