| 摘 要： | 在裂缝性储层、裂缝局部发育的油气藏开发中，采用小井眼水平井可显著提高单井产能，增加开发效益。小井眼水平井具有水平井高产能与小井眼低成本的特点，对提高地下油气资源的利用率有重要意义。阐述了小井眼水平井钻井技术在油气田开发中的应用及其适用性，给出了小井眼水平井钻井时选择开窗井下动力钻具的方法，并介绍了一种长寿命、能够克服其他钻具缺点的短半径开窗造斜工具，为小井眼水平井技术的应用提供了参考。

| Abstract: | Individual-well producing rate and develop benefit will increase apparently in using slim-hole horizontal well in the exploitation of fracture reservoir and part fracture reservoir. Slime-hole horizontal well, which characters with low cost and high productivity, can improve the development of oil and gas reservoirs. The application of slim-hole horizontal well in oil and gas reservoir development and its adaptability is present in the paper. The method to select dynamical drilling tools for windowing is given. And a short radius windowing and deflecting tool which has long life is introduced! which provides a reference for slim hole horizontal drilling techniques. . |
