摘要
吉达3井、吉达4井是中石油海外项目在乌兹别克斯坦内的费尔甘纳盆地上所钻的2口探井,这2口探井φ244.5mm技术套管固井面临长封固段、大温差等技术问题,针对这些固井难点,通过室内研究与现场试验,解决了φ244.5mm套管固井施工风险大、固井质量难以保证的问题,并且形成了费尔甘纳盆地长封固段、大温差技术套管固井的配套技术,为该地区的油气勘探提供工程技术保障。
Jida 3 well and Jida 4 well are the two exploratory wells that were drilled by CNPC Overseas Project Department in Fergana Basin in Uzbekistan,there were some cementing problems existent in the two wells,such as long sealing section and wide range temperature for φ244.5mm intermediate casing. According to these problems,laboratory study and field experiment were done to solve the problems of high operation risk and cementing quality,and the cementing technology suited for long sealing section and wide range temperature in Fergana Basin was formed through the two wells experiences.
