摘　　要：针对目前常用井壁坍塌监测手段是通过井下测量仪器实时采集数据,综合分析测井资料实现的,提出了一种有效利用地面测量数据实现对煤层气水平井井壁坍塌实时监测诊断的技术手段,基于支持向量机建立准确有效的诊断模型,并充分发挥了煤层气现有配套仪器的优势,在满足煤层气低成本开发的基础上,实现了井壁坍塌实时监测诊断。The common-used monitoring tools for wall collapse consist of real-time data collection by downhole measuring instrument, and comprehensive well-logging data analysis. Here, a new technology of real- time monitoring and diagnosis utilizing ground measurements for wall collapse in CBM horizontal wells is put for-ward. An accurately and effectively diagnostic model is established on the basis of support vector machine(SVM). Moreover, after meeting the requirement of low-cost CBM development, the real-time monitoring and diagnosis can be realized. Therefore, this technology has high practicability.
