摘要： A disengageable downhole tool (10) for use in the oil and gas industry. The tool can be decoupled from a work string to allow further tools to be operated from the work string on being run deeper into a wel. The tool is then picked-up by the work string on retrieval from the well. In one embodiment a milling tool (28, 32)is described having a hex-drive system for operation of the tool from the work string with coupling and decoupling being achieved via shear pins (40) and a mating ledge and shoulder.

摘要： A well cleaning tool for cleaning the inside walls of a well casing has at least two types of cleaning members; for example it may have a row of scraper blades and a row of brushes. The tool may also include one or more rotatable stabilizers that serve to maintain contact of the tool with the internal casing walls. The tool provides for obtaining the benefits of different types of cleaning members from a single trip into a well bore.

摘要： A tool for use in a well bore has a housing attachable to a work string or drill string wherein the housing supports a floating component that is free to move in the lateral or radial members relative to the housing within predetermined limits. The floating component is suitable for supporting active tool components such as wire bristles, scraper blades or other functional apparatus. Typically, the floating component is provided as a sleeve around the housing held within axial limits, while enabling radial movement.
摘要翻译：用于井眼的工具具有可连接到工作串或钻柱的壳体，其中壳体支撑浮动部件，该浮动部件在预定限度内相对于壳体在侧向或径向部件中自由移动。浮动部件适用于支撑活动工具部件，如线刷毛，刮刀或其他功能装置。通常，浮动部件被设置为围绕壳体的套筒，其保持在轴向限制内，同时能够进行径向运动。
