  • 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.
