摘要
渤海湾ＢＺ２６—２—２Ｄ井首次应用割缝尾管及管外封隔器技术成功地进行了特殊固井完井工艺。固井时采用 ２只封隔器，１号封隔器挤胀时用完井液；２号封隔器挤胀时用水泥浆，采用水泥浆挤胀封隔器还是首次应用。该技术的主要特点是：保护储层，作业安全，工具结构合理简单。为渤海地区开发潜山油藏提供了一个良好的完井方式，同时也摸索和总结出了一些宝贵的经验。
This paper summarizes the successful application of slotted liner and ECP(external casing packer) special completion technology firstly used in the Well BZ26-2-2D at Bohai Bay. Two packers were used in the completion. No. 1 packer was expanded by the completion fluid, whereas No. 2 packer was expanded by the slurry. It's first time to apply the slurry to expand the packer. The key characteristics of this technology are formation protection, operation safety, construction plan well -conceived and reasonable simple tool structure. The application of the technology provides a well completion method for the development of buried hill reservoir in Bobal Bay region, and gropes for and sum up the certain valuable experience for cementing and completion mechanism in the buried hill formation at Bobal Bay.
