摘要： A downhole apparatus is described comprising a main body coupled with a well tubing and a swellable mantle disposed on the main body. The swellable mantle expands upon contact with at least one predetermined fluid, and the main body comprises at least one opening for fluid flow between an exterior of the main body and the bore. An insert permits the passage of fluid, through the swellable mantle, between the exterior of the apparatus and the opening. In one aspect of the invention a screen filters solids between the exterior of the apparatus and the bore, and a swellable mantle comprises a first region which allows the passage of fluid between the exterior of the apparatus and the main body and a second region, circumferentially adjacent the first region, which substantially prevents passage of fluid. Corresponding well completion and production methods are also described.
摘要翻译：描述了一种井下装置，包括与井管连接的主体和设置在主体上的可膨胀套。可膨胀套与至少一种预定流体接触时膨胀，并且主体包括至少一个用于在主体的外部和孔之间流体流动的开口。插入件允许流体通过装置外部和开口之间的可膨胀套。在本发明的一个方面中，筛网过滤装置外部和孔之间的固体，并且可膨胀套包括第一区域和第二区域，第一区域允许流体在装置外部和主体之间通过，第二区域在周向邻近第一区域，其基本上防止流体通过。还描述了相应的完井和生产方法。

摘要： A downhole apparatus, for example a centraliser, comprises a swellable material which expands upon contact with at least one predetermined fluid. In a first aspect of the invention, a centraliser comprises a body and a plurality of formations upstanding from the body. In another aspect, a downhole apparatus comprise a throughbore configured to receive a tubular, a swellable member, and a rigid assembly integrally formed with the swellable member. The rigid assembly provides stand off to the apparatus in use. In a further aspect, the downhole apparatus has a first condition, before expansion of the swellable member in which a rigid assembly defines a maximum outer diameter of the apparatus. In a second condition after expansion of the swellable member, the swellable member defines a maximum outer diameter of the apparatus. In a preferred embodiment the rigid assembly is designed to flex or deform under an axial or radial load.

摘要： A downhole apparatus, such as a wellbore packer, is provided with a swellable member and a fluid supply assembly. The fluid supply assembly is to receive fluid and expose the swellable member to the fluid to cause expansion of the swellable member, and comprises a support structure for supporting the swellable member on the body. In a preferred embodiment, the support structure defines a chamber and is configured to allow fluid to flow and access the swellable member. A method of use and method of sealing a wellbore is described.

摘要： The present invention provides an apparatus and assembly for creating a seal in a wellbore around a cable or line. The assembly includes a longitudinal body (12) and a swellable portion (15) which comprises a material selected to increase in volume on exposure to at least one triggering fluid. The swellable portion (15) has a formation (18) open to the longitudinal surface which provides a pathway for a cable (22) or line to extend through the swellable portion (15), and an insert (24) of swellable material.
