摘　　要：分析了固井套管试压后声幅曲线变化的规律和声幅曲线变化的原因,指出套管试压后,套管与水泥环间的微环隙是造成声幅曲线变化的主要原因。现场试验证明,微环隙对声幅测井影响较大,但对后续作业影响不大,并给出了减少套管试压对水泥胶结质量影响的主要技术措施。This paper analyzes the variation rule of acoustic amplitude curve and causes of this variation after casing pressure testing, and points out that micro clearances between casing and cement sheath are the main factor of the variation Field tests prove that the micro clearances have critical influences on acoustic amplitude logging but later operations The corresponding measures reducing influences of casing pressure testing on cementing quality are provided in this paper
