欠平衡钻井技术及其应用与发展

Applications and Development of UBD Techniques

着重介绍了欠平衡钻井的适用范围、关键技术、特殊工具、钻井工艺要求以及一些在古潜山大缝裂缝性储层中的应用实例,并对欠平衡钻井技术的发展进行了展望。这对国内进一步开展欠平衡钻井技术工作(特别是对于古潜山大缝裂缝性储层)具有一定的借鉴之处。

This paper introduces the application ranges, critical techniques, special tools, drilling technological requirements for UBD drilling and the case history in fractured reservoirs in buried hill and predicts the development of UBD technique. This will provide a reference for the application of UBD technique.
