【摘要】 在常规压裂井试井分析过程中所使用的数据主要是停泵后的压降数据 ,而岩石发生破裂到停泵前这一段压裂施工压力数据则没有得到有效利用 ;同时 ,在压裂施工作业过程中也不能对裂缝的延伸状况进行动态监测。文章提出的水力裂缝模型的自动识别及动态监测技术 ,可以对岩石发生破裂到停泵前这一段压裂施工压力数据进行准确分析 ,自动确定裂缝模型并求取裂缝动态参数。这样就可以实时的知道裂缝发育、发展和闭合的情况 ,对于正确指导压裂施工作业以及获得优质裂缝具有十分重要的意义。更多还原

【Abstract】 Pressure-declining data are commonly used in the fracturing well test analysis. However, the fracturing data from rock breaking to pump stopping are not utilized effectively. Also, in the fracturing operation, the fracture-extending status can’t be monitored dynamically. With the technology of model automatic identification and dynamic monitor of hydraulic fracture proposed in the article, the fracturing data from rock breaking to pump stopping can be analyzed accurately. The fracture model can be confirmed and the fracture dynamic parameters can be calculated automatically. So, the growth, development and close of fractures can be known in real time. It is very significant to correctly guide the fracturing operation and obtain high quality fractures.更多还原
