摘　　要：叙述了井中声波CT技术系统的测量方式、数据采集和数据预处理以及CT正反演的基本方法,列举了在工程勘察和油气田开发中的应用实例,显示出井中声波CT成果为查明目标体的位置和圈定目标体的形态是有效的。同时也显示了井中声波CT技术作为一种精细勘查手段,具有开发潜力和应用前景。The measurement means of borehole acoustic CT technical system, data acquisition, data preprocessing and some forward and inverse methods are recounted in this paper, with some examples given concerning engineering survey and oil-gas field development and exploration. It is shown that the method of borehole acoustic wave CT is effective in detecting the position and the form of the target, and that the technique of borehole acoustic wave CT as a subde exploration method has development potential and application prospects.
