Abstract
On the basis of the geological background of Tarim foreland basin, this paper realizes parallel three-dimensional forward modeling in Kuqa area by using three-dimensional arbitrary difference precise integration algorithm. Compared with the conventional differential method, the three-dimensional arbitrary difference precise integration algorithm has greatly improved the precision by using the time domain local integral semi-analytical method to obtain the recursion operator of wave equations. In this paper, according to the actual examples analysis, the stability of calculation gets better owing to the stable factor constraints; by using an improved adaptive absorbing boundary and the parallelization of serial program, the time consumption of threedimensional forward modeling is greatly reduced and a large amount of three-dimensional forward modeling is finished.
