塔里木盆地顺北区块具有超深、高温、高压、高含硫化氢特征，其井身结构决定了完井工艺。现有的完井工具不能满足该区需要，特别是不适合5-1/2″小尺寸、高钢级、薄壁厚套管的封隔器，另外完井配套工具，特别是传统的球座、水力锚、压井滑套等可靠性较差，因此，开展了多项技术研发改进，实践证实其满足了顺北区块勘探开发的需求，解决了完井技术瓶颈问题，形成了一套符合顺北区块工况的完整的完井工具工艺体系。

The Shunbei oilfield is featured by ultra-deep, high temperature, high pressure and high hydrogen sulfide, and its well structure determined completion technology. Existing completion tools cannot meet the needs, especially not proper for casing packers of 5-1/2 ″small size, high steel grade and thin wall thickness. In addition, conventional completion kit tools, especially ball sitting, hydraulic anchor, sliding sleeve for well pressure control and so on, have a poor reliability. Therefore, a number of technology research and development was carried out. After application, it was proved that these new tools met the requirement of exploration and development, solved the technical bottleneck of completion, and established a complete well completion system in accordance with the working conditions of the Shunbei oilfield.
