声波反射成像测井能够获得井眼周围构造的重要信息,然而,由于接收到的反射波信号远小于井眼模式波、信噪比较低,且每次发射只有8道接收,因此应用常规的偏移成像处理方法成像效果不好。本文应用一种基于散射理论的等效偏移距偏移方法,对声波反射成像测井模拟数据及现场数据进行偏移处理。结果表明,与常规叠后深度偏移方法相比,等效偏移距方法可以有效提高覆盖次数,对于低信噪比的声波反射测井资料可以获得较好的井旁构造成像效果。 However, since the received reflected wave signal is much smaller than the borehole mode wave with a low signal-to-noise ratio and only 8 receive channels per shot, the conventional Offset imaging methods do not work well. In this paper, an equivalent offset migration method based on scattering theory is applied to offset the acoustic reflection imaging logging data and field data. The results show that compared with the conventional post-stack depth migration method, the equivalent offset method can effectively improve the coverage times, and the sounding reflection logging data with low signal-to-noise ratio can obtain good imaging results of well-side structures.
