| 摘 要： | 南堡35-2-A6mh井设计为一口多底水平分支井,下主支完成后,通过下入膨胀管,斜向器进行开窗侧钻上主支作业,并在上主支下入Ф177.8 mm尾管,然后套铣尾管及斜向器沟通上、下主支。介绍了NB35-2-A6mh井套铣尾管及斜向器的作业难点及现场施工作业中遇到的问题,探讨了该井未套铣成功的原因,并提出几点保证套铣作业顺利进行的建议,为以后海上4级完井作业中套铣尾管及斜向器提供借鉴和参考。 |

| Abstract: | NB35-2-A6mh well is a multilateral well.Run in expandable tubular and whipstock to drill the up-lateral and run in the Ф177.8 mm liner after the completion of the down-lateral,then washover the liner and the whipstock to connect the up-lateral and the down-lateral.In this thesis,the complexity and the field operation's problems of the washover liner and the whipstock are introduced,the reason of the unsuccessful washover is discussed,and some suggestions to assure washover are made.All of these can offer a reference for washover liner and whipstock in the TAML-Level 4 completion. |
| Keywords: | multilateral well washover whipstock drilling parameter |
