摘　　要：为满足山前高陡构造及逆掩推覆体地层钻井过程防斜打快的技术需求,填补我国在垂直钻井技术方面的空白,2004年以来中国石油渤海钻探工程有限公司工程技术研究院与德国智能钻井公司合作研发BH-VDT5000垂直钻井系统工具,现已获得成功。现场应用表明,该工具性能可靠,效果理想。在克深3、克深203和克深207等10口井试验应用,单趟最高进尺达1527.8m,日最高进尺410m,系统工作正常,井斜角小于0.5°,机械钻速提高70%以上。通过10口井的现场施工和工具检测维修,积累了现场施工经验,锻炼了现场技术服务队伍和检测维修队伍,提高了技术服务能力。现场应用证明,BH-VDT5000垂直钻井系统在高陡构造地层、逆掩推覆体地层的钻探中,防斜打直效果显著,提高了机械钻速,缩短了钻井周期,可进一步推广应用。In order to satisfy the technology needs of deviation control and fast drilling in precipitous and overthrust push nappe formation of the domestic oil and gas fields and fill the blank of the vertical drilling technology in China, BHDC Engineering Technology Research Institute has developed vertical drilling system tools with the German Smart Drilling Company since 2004. Through field experiment, the performance and reliability of the VDT5000 vertical drilling tools have been verified, achieving desired results. Through test and application in 10 wells, including Well Keshen3, Well Keshen203 and Well Keshen207, the highest single trip drilling depth was 1527.8m, the highest daily drilling depth was 410m, the system worked properly,the deviation angle was less than 0.5° and the ROP rose by more than 70%. Through 10 wells on-site construction and the maintenance and detection oftools, on-site construction experience has been accumulated, on-site technical service team, and testing and maintenance teams were exercised, and technical service capabilities were improved. Field application proved that the BH-VDT5000 vertical drilling system in fast drilling of precipitous and overthrust push nappe formation has significant effectiveness in deviation control, increasing ROP and shortening drilling cycle, which could be further widely applied.
