摘要
目前,水平井开发为了快速实现油井高产目的,一般选择用潜油泵进行强采的方式,使得开采后的近井地带出现不同程度的亏空情况,油井中随之会有大量出砂情况.砾石充填完井通过砾石充填能够有效避免地层砂进入井筒,并使得井壁可以保持一定渗流能力并实现油井产量的增加.基于此,对水平井裸眼砾石充填完进工艺技术进行研究,以期为相关技术人员现场应用提供参考.
Abstract
At present,in order to quickly achieve the goal of high oil production in horizontal well development,submersible pumps are generally used for strong production,resulting in varying degrees of deficit in the near wellbore area after extraction,and a large amount of sand production in the oil wells.Gravel filling completion can effectively prevent formation sand from entering the wellbore,maintain a certain permeability of the wellbore,and achieve an increase in oil well production.Based on this,the article conducts research on the technology of gravel filling in the open hole of horizontal wells,in order to provide reference for relevant technical personnel for on-site application.
