| 摘 要： | 八扇区水泥胶结测井仪是一种评价水泥胶结质量及探测孔穴孔道的声波测井仪。讨论了该仪器的结构、原理及优势。实际应用效果表明，该仪器一次下井可测得8个扇区套管水泥分布图、3ft声幅曲线、5ft变密度图，且不受重泥浆、油基泥浆、井内套管厚度等影响，能评价第一界面存在的槽道、孔洞的位置、大小及分布情况．是检测固井质量和管外窜槽的有效测井技术之一。

| Abstract: | Sector Cement Bond Tool(SBT) was an acoustic log tool for inspecting the quality of cement bond around the circumference of the casing for measuring the pore paths.SBT was able to measure the casing cement distribution in eight individual sectors and provided 3-foot amplitude/travel time and 5-foot full waveform displays in a single logging pass.This technology is not affected by heavy mud,oil-base mud,and casing thickness in the well,and it can demonstrate the mortise,the hole position,the size and distrib... |
