| 摘 要： | 涪陵二期建产区地质构造比一期更加复杂，目的层埋深更深，水平段倾角变化较大，这些客观因素造成钻井施工困难，钻井周期普遍延长。焦页91平台是部署在二期江东区块西南部的边缘井，地质条件复杂，钻井工程施工难度大。本文深入分析了该平台的第1口井焦页912HF井施工过程中遇到的复杂情况以及造成钻井周期长的主要原因，在后续2口井的施工过程中，针对第1口井出现的问题，采取改进堵漏措施，钻头、螺杆优选，优化井眼轨道，配套提速工具，提高钻井液性能，使用旋转导向工具等技术措施，精细施工，取得了良好的效果，钻头行程和机械钻速大幅提升，钻井周期大大缩短，为涪陵二期江东区块钻井施工提供了经验。

| Abstract: | In the second stage of Fuling gas field development, the geological structure is more complex than that in the first stage, with the deep buried depth of the target layer and the varying dip angle over the horizontal section. These objective factors make drilling difficult and the drilling duration is generally extended. Jiaoye 91 platform is located in the southwest edge of Jiangdong Block, where the geological conditions are complex, and drilling is difficult. In this paper, the complex situation encountered in the drilling process of the first well JY912HF in the platform is analyzed, and the main reasons for the long drilling duration are analyzed. During the construction of the following two wells, technical measures, such as improving leak plugging measures, optimizing bits and PDM, optimizing the borehole trajectory, matching downhole tools, improving drilling fluid performances and using rotary steering tools, were adopted. Fine construction has been carried out to solve the problems of the first well, and good results have been achieved. The bit run and ROP have been greatly improved, and the drilling duration has been greatly shortened, providing the construction experience for drilling in the area. |
