浅层水平井钻完井技术在曹妃甸油田的应用

Shallow horizontal well drilling and completion technology applied in Caofeidian oilfield

曹妃甸油田油藏埋深浅,主力油层主要位于上第三系地层的明化镇组、馆陶组地层,主要采用水平井方式进行开发。针对油田的地质特点,根据地层特征情况,在充分吸收前作业者作业经验的基础上,通过近两年的调整井作业实践和验证,形成了一套具有油田特色的,适用于曹妃甸油田的浅层水平井钻完井技术,成功解决了作业实践中存在的包括井眼轨迹控制、管柱下入困难等问题,取得了良好的应用效果。

Caofeidian oilfield is shallow,the main reservoir is located on the main Tertiary strata Minghuazhen GuantaoFormation,the main way to develop the use of horizontal wells. For geological features oilfield drilling and completion aspects Aftercareful research,the full argument communication and related case studies,based on stratigraphic features case,on the basis offully absorbed by the job before the job experience,by adjusting the nearly two years of well operation practices and verification,has formed a distinctive oil for Caofeidian oilfield shallow horizontal well drilling and completion technology,successfully resolvedthe jobs that exist in practice includes well trajectory control,into the next column and other difficult issues,and achieved goodapplication effect.
