一种方位声波固井质量评价方法及测试应用
A method for azimuthal acoustic cementing quality evaluation and applications
摘要
Abstract
The conventional cementing quality evaluation logging tools lack the ability of azimuthal resolution. Therefore,we propose a new method for evaluating cementing quality and develop the related azimuthally acoustic bond tool(AABT).The AABT uses two sets of arc array transmitters with 3D radiation characteristics.Compared with the traditional monopole and dipole transmitters,the tool is possible to radiate acoustic energy to the 3D space in any direction since using the acoustic phased array transmitter.This paper introduces the structure,measuring method and field examples of the AABT.The results show that the AABT can evaluate circumferential cementing quality of Interface-Ⅰ by the first arrival amplitude imaging.In the case of good cementing quality at the Interface-Ⅰ,we can further evaluate circumferential Interface-Ⅱ cementing quality by the formation wave imaging.关键词
