在环江油田进行定向井施工中，存在地层规律认识不够、自然增或降斜严重、起下钻及定向调整次数多、随钻测斜仪器落后、纯钻利用率低等问题，严重影响了渤海钻探10万米进尺的完成。针对这种情况，在采用“四合一”钻具组合的基础上，配合MWD无线随钻技术，很好的解决了这个问题，使起下钻次数明显减少，机械钻速得到很大提高。

Huanjiang oilfield directional drilling has greatly affected the course of 1 million meters drilling in the Bo-hai Sea for the reason of leaking knowledge of stratum patterns and frequent up -and-down drilling and directional adjustments .In view of this situation , we use the “ four in one” drilling assembly and MWD wireless drilling tech-nology to solve this problem well , making the tripping frequency significantly reduced and the mechanical drilling speed improved , which has reached the optimal and fast construction of directional drilling .
