摘要： A downhole cleaning apparatus (10) comprising a tubular body (12). The tubular body (12) comprises comprising a plurality of openings (20) therethrough. Each opening (20) defines at least part of a helix extending longitudinally and circumferentially about the tubular body (12). The downhole cleaning apparatus (10) also includes a plurality of cleaning elements (22). Each cleaning element (22) is configured to extend through an opening (20) and to extend outwards from an outer surface of the tubular body (12). The cleaning elements (22) are distributed about the tubular body (12) and each cleaning element (22) defines at least part of a helix extending longitudinally and circumferentially about the tubular body. The openings (20) and the cleaning elements (22) are grouped to define a plurality of substantially continuous helical paths (18). Each helical path (18) extends substantially end to end of the tubular body and the helical paths (18) are distributed relative to each other to define a cleaning surface of at least 360 degrees.

摘要： A downhole milling tool (100) operable to remove unwanted debris from an interior wall of a pipeline, well casing or other tubular in which the tool (100) is deployable. The tool (100) comprises a hollow tool body (1, 11) mountable on a drill string and an annular element (8) mountable about an outside surface of the tool body (1). The annular element (8) houses at least one elongate milling blade (12). The at least one milling blade (12) is configured such that it always projects from an outside surface of the annular element (8) and includes an elongate cutting face (36). The annular element (8) is configured to be rotatably coupled to the tool body (1) in an active state and rotatably decoupled from the tool body (1) in an inactive state such that the annular element (8) and the tool body (1) are rotationally dependent when coupled and rotationally independent when decoupled. The cutting faces (36) are each configured to be operable to remove unwanted debris only when the annular element (8) and the tool body (1) are rotationally dependent, such that, in use, rotation of the tool body (1) effects operation of the milling blades (12) to remove unwanted debris and to be inoperable to remove unwanted debris when the annular element (8) and the tool body (1) are rotationally independent.
摘要翻译：井下铣削工具（100），其可操作以从管道，井套管或其他管状物的内壁去除不想要的碎屑，其中工具（100）可部署在其中。工具（100）包括可安装在钻柱上的中空工具主体（1,11）和可围绕工具主体（1）的外表面安装的环形元件（8）。环形元件（8）容纳至少一个细长铣削刀片（12）。所述至少一个铣刀（12）构造成使得其始终从所述环形元件（8）的外表面突出并且包括细长切割面（36）。环形元件（8）被构造成在活动状态下可旋转地联接到工具主体（1），并且在非活动状态下可旋转地与工具主体（1）分离，使得环形元件（8）和工具主体 1）在耦合时是旋转依赖的，当耦合时耦合和旋转独立。切割面（36）各自被构造成仅当环形元件（8）和工具主体（1）旋转相关时才可移除不想要的碎屑，使得在使用中，工具主体（1）的旋转产生铣削刀片（12）的操作以去除不想要的碎屑，并且当环形元件（8）和工具主体（1）是旋转独立的时，不能够去除不需要的碎屑。
