| 摘 要： | 渤海35油田沙河街组水平井穿层较多，整体水平段砂泥岩比例不稳定、交互较多，若处理措施不当，易发生井壁失稳，也易造成防砂管柱下入困难、盲管配管较多以及投产后筛管堵塞严重的问题。通过钻进过程中使用随钻工具及时跟踪，调整井眼轨迹，对钻井液体系、钻井工艺技术等方面进行调整，有效提高了渤中深部地层强非均质水平井油层钻遇率,得出了一些实际操作的方法和经验，对深部地层强非均质水平井现场实施具有较高的参考价值。

| Abstract: | The horizontal well drilling passes through different strata in Shahejie formation of Bohai 35 oilfield, sandstone-mudstone ratio is unstable in the whole horizontal section with lots of interbedding, which is easy to lead to wall instability, difficulty of sand control pipe running, many blind pipes setting and serious screen pipe blockage in production. By the use of while-drilling tools, timely tracking and adjustments of borehole trajectory, drilling fluid system, drilling technology and some other aspects, the oil reservoir encountering rate in severe heterogeneous reservoir of deep strata in middle Bohai Sea has been effectively improved. Some operation methods and experiences can be reference to the field construction of severe heterogeneous reservoir horizontal well in deep strata. |
