大位移超深井录井方法探讨

随着大位移超深井钻井数量的增加和钻井工艺的改进,综合录井如何尽快适应这一挑战,已成为录井界攻关的重要课题之一。该文结合胜利油田某大位移超深井钻探过程中的录井实践,在正视大位移超深井给录井工作带来影响的基础上,详尽地阐述了岩屑录井取样与分析、气测录井与岩屑荧光录井互补、结合钻时和工程参数变化落实岩性及油气显示的录井方法。该方法对同类型井的录井施工具有指导意义。

The mud logging method for large-displacement deep wells

As more and more large-displacement ultra-deep wells and the improvement of the drilling technique, how mud logging adapted to the challenge has become an important project to be tackled in the mud logging industry. According to the drilling practice for a large-displacement ultra-deep well in Shengli Oilfield and at the base of paying more attention to the influence on mud logging, the paper introduced, in detail, the mud logging technique of the lithology identification and oil & gas show evaluation with the cutting, gas and fluorescent logging associated with drilling rate and the other engineering parameters. The method is of guide significance for mud logging in the similar wells.
