摘要
介绍动态 (电位 )法测定煤层压裂裂缝方位、长度等参数的测试技术 ,它是针对煤层的固有特点 ,在室内进行大量物理模型试验 ,结合现场试验后取得的科研成果。文中简要阐述动态 (电位 )法测试技术的基本原理、测量方法及测量仪器的基础上 ,着重对山西吉试 1井、大港油田西 36— 10— 3井的现场应用效果进行分析 ,证明动态 (电位 )法测试技术的可行性及在煤层 (油 )气田勘探与开发领域中所发挥的重要作用
The article introduces the dynamic (electric potential) method to measure the fracture parameters such as azimuth,length,etc. for coal-bed fracturing. Based on many in-house physical model experiments and field tests,aiming to the inherent characteristics of coal beds,the dynamic (electric potential) method is developed. The paper introduces the basic principle,the measuring method and the measuring instruments of the dynamic (electric potential) method. Then,the application results of the method are analyzed for Well Jishi 1 in Shangxi province and Well Xi 36-10-3 in Dagang Oil Field. The results prove the feasibility of the dynamic (electric potential) method and its major role in exploration and development of coal-bed gas.
