Abstract: Given the inversion calculation cannot compute the position of array exactly, the dynamic modeling of towed vehicle-seismic array-drogue was purposed, and the position of array was calculated by dynamic simulation. The position of seismic array was calculated by inversion calculation and dynamic simulation, respectively. Then, the travel times of the reflected wave by seabed were calculated with respect to the position of the array. The comparison between the calculated travel times and real seismic records indicated that the malpositions were shown in the inversion calculation, while the result by dynamic simulation was stable and matched well with real records. Dynamic analysis was an efficient method in position prediction of seismic array.

Key words: deep-towed seismic array, drogue, dynamic modeling, position prediction, inversion claculation
