摘要： A tool retainer (3) for use in a line lubricator comprises a tool catcher arrangement (8) for catching a tool and a resilient member (9) which biases the tool catcher arrangement towards a tool catching configuration in which the tool catcher arrangement is capable of catching a tool when the tool is pulled into engagement with the tool catcher arrangement along an axial direction. The tool retainer comprises an indexing arrangement, wherein the tool catcher arrangement and the indexing arrangement are configured to interact so as to selectively release a caught tool in response to a predetermined sequence of axial movements of the tool catcher arrangement. The resilient member may resist axial motion of the tool catcher arrangement under the action of a force exerted on the tool catcher arrangement by the tool as the tool is pulled into a lubricator at the wellhead of an oil or gas well on the end of a line.

摘要翻译：用于线路润滑器的工具保持器包括用于抓住工具的工具捕获器装置和将工具捕获器装置偏压到工具捕捉构造的弹性构件，在该工具捕捉构造中工具抓取器装置能够在工具拉动时抓住工具沿着轴向方向与工具捕获器装置接合。工具保持器包括分度装置，其中工具捕获器装置和分度装置被配置为相互作用，以便响应于工具捕集器装置的预定的轴向运动顺序选择性地释放所捕获的工具。弹性构件可以在工具被拉入位于管线端部的油或气井的井口处的润滑器中的作用下由工具施加在工具捕集器装置上的力的作用下抵抗工具捕集器装置的轴向运动。

摘要： A wireline device for use in downhole operations may comprise at least one of a position indicator arrangement, a latch arrangement and a seal arrangement. The position indicator device may alert a winch line operator of the approach of a downhole toolstring to a stuffing box located at the wellhead of an oil or gas well. This may permit the winch line operator to control winching of the wireline so as to avoid retraction of the toolstring into engagement with the stuffing box thereby minimising the resulting risk of wireline breakage. The latch arrangement may retain the tool string relative to a wellhead housing so as to avoid the toolstring dropping back into the wellbore in the event of wireline breakage. The seal arrangement may prevent a hydrocarbon leak from the wellbore to an environment external to the wellhead housing in the event of wireline breakage.
摘要翻译：用于井下操作的有线装置可以包括位置指示器装置，闩锁装置和密封装置中的至少一个。位置指示装置可以提醒绞车线操作者将井下工具串进入位于油井或井口井口处的填料箱。这可以允许绞车线操作者控制电缆的绞线，以避免工具串缩回到与填料函接合，从而最小化导致电线断线的风险。闩锁装置可以相对于井口壳体保持工具串，以避免在有线断裂的情况下工具串落回到井筒中。在电缆断裂的情况下，密封装置可以防止烃从井眼泄漏到井口壳体外部的环境。

摘要： Apparatus (10) and method for controlling the position of a downhole tool (12) within a passage (14), comprising means (16) for detecting the position of the tool in the passage, the detecting means being coupled to control means (18) for moving said tool within said passage, whereby when the tool reaches a predetermined position (20), the detecting means sends a signal to said control means to stop further movement of the tool. The detection means may comprise a detection member (28) pivotally mounted within said passage for pivotal movement between an open or partially open position and a closed position.
