    • A sealing system can include an annular seal comprising a resilient material, and a spring which applies a compressive force to the seal as a resilience of the material diminishes, the spring being external to the seal. A sealing method can include installing a seal in a well tool, the seal being compressed radially as a result of the installing, and a spring external to the seal exerting a compressive force on the seal. A well tool can include a seal radially compressed between seal surfaces of the well tool, due to the seal having a greater radial dimension as compared to a radial distance between the seal surfaces, and a spring which exerts a compressive force on the seal, the spring being external to the seal.
    • 密封系统可以包括包括弹性材料的环形密封件和当材料的弹性减小时向密封件施加压缩力的弹簧,弹簧在密封件的外部。 密封方法可以包括在密封件工具中安装密封件,密封件由于安装而径向压缩,密封件外部的弹簧在密封件上施加压缩力。 由于密封件与密封表面之间的径向距离相比具有更大的径向尺寸,以及在密封件上施加压缩力的弹簧,井工具可以包括径向压缩在井工具的密封表面之间的密封件, 弹簧在密封件的外部。

    • A formation tester tool can include a longitudinal probe drill collar having a surface, a formation probe assembly located within the probe drill collar, the formation probe assembly including a piston reciprocal between a retracted position and an extended position beyond the probe drill collar surface, the piston being slidingly retained within a chamber, a seal pad located at an end of the piston, the seal pad including an outer surface defining a partial cylindrical surface. The piston includes an outer surface having non-circular cross-sectional shape and the chamber includes an inner surface having a non-circular shape similar to the shape of the piston outer surface. The formation tester tool can include interchangeable draw down assemblies and a flow bore having a curving path.
    • 地层测量仪工具可以包括具有表面的纵向探针钻铤,位于探针钻铤内的地层探测器组件,地层探测器组件包括在缩回位置和超出探测钻铤表面的延伸位置之间往复运动的活塞, 活塞滑动地保持在室内,密封垫位于活塞的端部,密封垫包括限定部分圆柱形表面的外表面。 活塞包括具有非圆形横截面形状的外表面,并且该腔室包括具有类似于活塞外表面形状的非圆形形状的内表面。 地层测试仪工具可以包括可互换的下拉组件和具有弯曲路径的流动孔。
