摘　　要：针对中原油田油水井套管损坏严重,常规工艺技术难以解决套管长距离多处损坏的问题,开展了在13 9.7mm套管内下10 1.6mm套管延迟固井技术的研究与应用。该工艺采用10 1.6mm无接箍套管及套管扶正器,并应用延迟固井工艺,确保了13 9.7mm和10 1.6mm套管间的固井质量。该工艺作为钻开发调整井的替代技术,具有良好的经济效益。In the light of greatly damaged well casing at long distance and in many places in Zhongyuan oilfield, the conventional technology can't solve this problem, casing delayed cementing technology of 101.6mm casing put into 139.7mm casing is researched. The cementing quality between these two casings may be ensured by applying 101.6mm casing without collar and casing centralizer and delayed cementing technology. Good financial profit can be obtained applying this technology as alternate technologies of drilling development adjustment wells.
