UBD/MPD技术标准现状分析

Study on Technical Standards of UBD/MPD

摘要:

近年来，欠平衡钻井（UBD）和控制压力钻井（MPD）因能大幅度提高机械钻速、有效降低井下复杂情况的发生、减少非生产时间而得到了飞速发展，国内外也对两项技术制定了相关标准。从石油行业标准、IADC标准、API标准入手，着重讨论欠平衡钻井和控制压力钻井的标准现状，探讨建立控制压力标准应包含的主要内容。

Abstract:

In recent years, under-balanced drilling (UBD) and managed pressure drilling (MPD) have been rapidly developed thanks to their contributions to penetration rate improvement and effective reductions in both the occurrence of down-hole problems and non-productive time. At present, a considerable number of industry standards have been made for the above two techniques in China and abroad. Starting from oil industry standards, IADC standards and API standards, the paper focused on the discussion on the current situation of standards of UBD and MPD, studied the main contents in the future standards of managed pressure drilling in China.
