【Abstract】 This paper introduced a feasible method for analyzing parameter of the field layouts to improve data acquisition.First,2D geology model is built based on the geology task with the known seismic interpretation results.Then the shot records and zero-offset records of the model are modeled by ray tracing method.Upon the modeling results,the parameter of the field layouts such as maximum distance from shot to geophone,trace to trace distance etc.,are determined.A real case verifies the correctness of the data processing and interpretation,as well as the reasonableness of the designed field layouts.In the process of seismic exploration for the complex geological structure,the application of 2D seismic model forward technology to proof the 2D observation system design is a successful method.It can effectively monitor the quality technology work,instruct thd field production work timely and also can prove the exactness of the previovs interpretation.更多还原
