外钓岛-册子岛水平定向钻穿越施工技术研究

Research on Construction of Waidiao-cezi Project by HDD

外钓岛-册子岛水平定向钻穿越工程穿越曲线超长，地质条件极为复杂，施工难度前所未有。通过对穿越工程特点及施工难点的分析，考虑到实际施工中的技术要求和工程要求，采取了先进的技术措施，实现了外钓岛-册子岛长距离、复杂地层的海底管道穿越，为国内外同类条件的水平定向钻穿越施工积累了宝贵的经验。

The crossing curve of Waidiao-cezi directional drilling project is extraordinary long and geological conditions are very complicated, the constructional difficulties are unprecedented. While Characteristics and difficulties of the project are analysed and the requests of constructional technology are considered, technology measures are adopted. The accomplishment of Waidiao-cezi offshore pipeline crossing provides constructional experiences in the realm of long-distance and complicated geological directional crossing.
