- Abstract
Zhongyuan Oilfield Wenliu &Pucheng joint region tectonics locate in eastern Puyang topographic depression. Since numerous fault blocks exist in the region, and water emerging, circulation lost and severe kicking happen, cementing operations are facing big challenges. By serious analysis on each block stratum, and effective anti circulation loss technical measures, and combined with sectional pressure stabilization, partial plugging, overall anti channeling, annular back pressure adding measures etc., cement slurry system was optimized. Taking turbulence and plug flow complex displacing technology, the cementing difficulties were effectively solved in Wenliu & Pucheng joint region, and it made technical support to the future cementing operations and accumulated experience for cementing works in similar complex regions.
