介绍了远探测声波反射波成像测井仪器的原理、主要作用和技术特点;用实例分析了在井旁裂缝性储层评价中的应用效果.通过多口井的实际应用表明,在远探测声波反射波成像图上没有反射信息一定为致密层,而有反射信息说明该处存在波阻抗差.研究发现,远探测声波反射波成像测井在碳酸盐岩等裂缝性储层中能在一定程度上解释测井评价与试油矛盾,提高了声波测井的径向分辨率;仪器能对井壁之外3～10 m范围内的裂缝、断层、界面进行清晰成像;能扩大识别储层的有效厚度,指导压裂施工,为油气地质储量计算提供可靠依据.给出了井壁外实际储层的有效厚度.

Given is a brief introduction to the principles, the main functions and the technical characteristics of remote exploration acoustic reflection imaging logging, and analyzed are the applied results in evaluating fractured reservoirs adjacent to the wellbore with the examples of two wells. Several actual loggings prove that, where there is no reflected information on the remote exploration acoustic reflection images, there is compacted zone, while there is the information on the images, there is poor wave impedence. The reason caused such impedence should be practically analyzed. The studies indicated the remote exploration acoustic reflection imaging logging technique can solve the problems between well logging interpretation and oil testing to a certain extent, which exist in carbonate rock and the other fractured reservoir, improve the radial resolution of acoustic logging, the investigation depth is 3～10 m from borehole wall, and also give out the net pay thickness of the actual reservoirs of outer borehole wall.
