| Abstract: | Serious lost circulations occurred while ultra low pressure formations encountered during Yuncan 1 Well drilling. Therefore, using aerated drilling fluids and under balanced drilling techniques can not only meet with the geologic requirements but also ensure the normal drilling. This paper systematically introduced the application background and technological process of aerated mud drilling operations in Yuncan 1 Well and its wellhead devices, field operations, meanwhile, analyzed the performing effectiveness. |
