本文提出共炮记录正演模拟检波点下延记录原理，用单程声波方程实现了非零偏移距地震记录的正演模拟。这种方法突破了全波方程非零偏移距波动方程正演模拟的限制，克服了全波方程处理中多次波、虚逝波和地表边界条件的问题，并且运算快、精度高。
In this paper, the principle of descending recording of positive probe point of common gun record is proposed, and the forward simulation of non-zero offset seismic record is realized by using one-way acoustic wave equation. This method breaks through the limitation of the forward modeling of wave equation of non-zero offset in full wave equation, overcomes the problem of multiple wave, evanescent wave and surface boundary conditions in full wave equation processing, and has the advantages of fast calculation and high precision.
