摘要： A process for sealing off one or more segments of a gravel packed well to reduce the production of undesirable fluids. The process includes the installation of a removable plug and the installation of a removable sealant at a location in the gravel packing to separate portions of the formation that produce desirable products from portions that produce less desirable products. A flow poison is then squeezed into the portion of the formation that produces less desirable products. With wireline or other low-cost wellbore workover systems, access is re-engaged with the preferred formation including removal of plugs and sealants without mechanical drilling. The process allows increased production of preferred fluids by preventing less or non preferred fluids from displacing the preferred fluids and also reduces lifting costs that would otherwise be expended for lifting and expenses related to separating and disposing of non preferred fluids.
摘要翻译：用于密封砾石填充井的一个或多个段的方法以减少不需要的流体的产生。该方法包括安装可移除的塞子以及在砾石填料中的位置处安装可移除的密封剂，以将形成理想产品的部分分离成产生不理想产品的部分。然后将流体毒物挤入地层中产生较不理想产品的部分。使用有线或其他低成本井筒修井系统，可以重新接合优选地层，包括拆除塞子和密封剂，而不需要机械钻孔。该方法允许通过防止较少或不优选的流体排出优选的流体来增加优选流体的生产，并且还减少否则将用于提升的起重成本以及与分离和处理非优选流体有关的费用。

摘要： This invention relates to a process for isolating one or more segments of a gravel packed well from other segments to treat the isolated segments and easily re-establish flow from the other segments after the treatment. The treatment includes techniques for enhancing or permanently blocking production from the isolated segment. The process includes the installation of a removable plug and a permeability poison that forms a fluid seal to prevent longitudinal fluid flow along the annular production space outside the tubular production pipe. With wireline or other low-cost wellbore workover systems, access is re-engaged with the secluded formation including removal of plugs and fluid seals within the tubular production pipe. The inventive process allows enhanced recovery of fluids by focusing treatments on problem areas without harming productive segments of the well.
摘要翻译：本发明涉及一种从其他部分分离砾石填充井的一个或多个区段的方法，以处理分离的区段，并且在处理之后容易地从其他区段重新建立流动。该治疗包括用于增强或永久阻断分离区段的生产的技术。该方法包括安装可拆卸塞子和形成流体密封件的渗透性毒物，以防止纵向流体沿着管状生产管道外部的环形生产空间流动。使用有线或其他低成本井筒修井系统，通道将重新与隐蔽地层结合，包括在管状生产管道内拆除塞子和流体密封。本发明的方法允许通过将处理聚焦在问题区域上来增强流体的回收，而不损害井的生产段。
