摘要： A gripping element (100) for incorporation into a track (175) of a downhole tractor (101). The gripping element may be configured with an arcuate or curved surface (201) in order to roughly match the arcuate nature of a well through which the downhole tractor is advanced. Due to the matching arcuate surfaces of the gripping element and the wall of the well, problems associated with uneven wear on the tracks may be avoided. Furthermore, damage to the well wall may be minimized as a result of the substantially matching surfaces of the well wall and the track made up of such gripping elements. Additionally, the gripping element may be made up of primarily a monolithic body (200) in order to avoid challenges presented by some segmented body configurations.

摘要翻译：用于结合到井下拖拉机的轨道中的夹紧元件。夹紧元件可以被构造成具有弓形或弯曲表面，以便大致匹配井下拖拉机通过其进入的井的弧形特性。由于夹紧元件和孔的壁的匹配的弧形表面，可以避免与轨道上的不均匀磨损相关的问题。此外，由于井壁和由这种夹持元件组成的轨道的基本上匹配的表面，井壁的损坏可能被最小化。此外，夹紧元件可以由主体构成，以避免由某些分段的主体构型呈现的挑战。

摘要： A downhole tractor (10) is provided that may be used in open or cased wells, and is also designed for use in open holes having a variety of soil/formation consistencies (e.g., soft, firm, rigid, etc.), varying diameters and non-uniform and irregular bore profiles. The tractor may include a track assembly (28) including a plurality of idler wheels (34) and a continuous track (30) rotatably disposed around the idler wheels. A motor (22) may be adapted to rotate the track around the idler wheels. Upper (36) and lower (38) arms may be pivotally connected to opposite ends of the track assembly and pivotally connected to a tractor housing (26). An actuator arm or link assembly (44) may be provided to impart an outward force to the track assembly to move the track assembly outwardly into an open position and a retracting force to retract the track assembly into a closed position. A rotatable screw (42) may be connected to a second motor, or a rod may be connected to a hydraulic system, to actuate the actuator arm or link assembly.
摘要翻译：提供一种井下拖拉机（10），可用于开放井或套管井，并且还设计用于具有各种土壤/地层一致性（例如，软，坚固，刚性等）的开放孔，变化的直径和不均匀和不规则的孔型材。拖拉机可以包括轨道组件（28），轨道组件（28）包括多个惰轮（34）和围绕惰轮可旋转地设置的连续轨道（30）。马达（22）可以适于围绕惰轮旋转轨道。上部（36）和下部（38）臂可以枢转地连接到轨道组件的相对端并枢转地连接到拖拉机壳体（26）。可以提供致动器臂或连杆组件（44）以向轨道组件施加向外的力以将轨道组件向外移动到打开位置和缩回力以将轨道组件缩回到关闭位置。可旋转螺杆（42）可以连接到第二马达，或者杆可以连接到液压系统，以致动致动器臂或连杆组件。
