近日，中原石油工程公司完成东北油气分公司梨9侧井88.9毫米套管产层固井施工，固井质量优良，创国内该尺寸套管单级固井最深4632.79米纪录。

梨9侧井是一口挖潜定向开发井。针对施工难点，中原石油工程公司成立固井技术攻关工作组，开展室内水泥浆化验，调配出流变性能良好、抗高温且具有长期封固效果的水泥浆体系，确保满足各项施工要求。施工中，他们严格按照设计要求控制水泥浆密度、施工排量等参数，保障了施工圆满完成。

Recently, Zhongyuan Petroleum Engineering Company completed the 88.9mm casing production formation cementing construction of the Li 9-side well of Northeast Oil and Gas Company, and the cementing quality was excellent, setting a domestic record for the deepest single stage cementing of this size casing 4632.79 meters.

Pear 9 side well is a potential exploitation directional well. In view of the construction difficulties, Zhongyuan Petroleum Engineering Company set up a task force on cementing technology, carried out indoor cement slurry testing, and deployed a cement slurry system with good rheology, high temperature resistance and long-term sealing effect to ensure that various construction requirements were met. During the construction, they strictly controlled the parameters of cement slurry density and construction displacement in accordance with the design requirements to ensure the successful completion of the construction.
