Abstract: Exploration degree is high in Jizhong Depression. Currently, most of the structural targets in the middle and shallow layers have been located and brought under progressive development in the medium and later stages. The oil and gas reserves and production are inevitably on the decline, making exploration of the structures in the middle and shallow layers more and more difficult and affecting a healthy development of the company. Comparably speaking, exploration degree is relatively low in deep buried hill and its inner curtain, where there is a great potential for exploration. They are the main exploration fields at the present time. However, most of the current seismic data about this field have the problems of low signal-noise ratio, poor imaging and inaccuracy. Therefore, the study is focused on the target zone of Fengheying buried hill and the seismic geological conditions in the target zone. Good results have been achieved in study of the seismic acquisition method, such as times of fold, receiving line interval, channel density and geometry of uniformity. With the quality of seismic data remarkably improved, a set of seismic acquisition method has been summarized to facilitate exploration of deep buried hill and its inner curtain in Jizhong Depression so as to provide favorable basis for seismic data acquisition in the similar areas.
