针对中原油田断块多,渗透率差异大的地层特点,详细介绍了自吸式水泥充填裸眼封隔器的工作原理及特点,并以庆92-20井为例介绍了该工具在中原油田的现场应用情况及施工要点;该技术有效地避免了地层流体在水泥浆候凝失重期间对井筒所造成的油气水侵,解决了因普通封隔器密封胶皮老化,造成的封隔器密封的失效;提高了油井的适用寿命及产能,获得了较高的经济效益。 Aiming at the characteristics of the stratum with large fault block and large permeability in the Central Plains, the working principle and characteristics of the self-priming cement-filled open-hole packer are introduced in detail. Taking Qing 92-20 well as an example, Field application and construction essentials. The technique effectively avoids the oil and gas water invasion to the wellbore caused by the formation fluid during the weight loss of cement slurry, and solves the failure of the packer seal caused by the aging of the conventional packer sealing rubber. ; Improve the useful life of oil wells and production capacity, access to higher economic benefits.
