Abstract: A sensor configuration including a centralizer having a rib, a hollow defined within the rib, and a sensor positioned within the hollow. A borehole system including a borehole, a tubular string disposed within the borehole, a centralizer having a rib, and the rib defining a hollow, disposed upon the tubular string, a sensor within the hollow. A method for acquiring data in a borehole including running a sensor configuration as in any prior embodiment on a tubular string into a borehole, cementing the tubular string in the borehole, and sensing with the sensor configuration, a parameter in the borehole.

Abstract: An annularly shaped modular debris barrier can be mounted to an internal or an external member that are spaced apart to define an annular gap that could collect debris. The modules rotationally lock. Modules have circumferential segments that can be initially spaced apart to promote flexing that can occur when there is relative axial movement between the structures that define the annular gap. The gaps between segments are circumferentially offset as between adjacent segments to create a labyrinth through which the fluid can move in opposed direction while at the same time causing the debris to be retained. The segments stay in a flexed condition to exert a contract stress on the free ends thereof that touch the adjacent structure.

Abstract translation: 环形的模块化碎片障碍物可以安装到间隔开的内部或外部构件，以限定可以收集碎屑的环形间隙。 模块旋转锁定。 模块具有圆周段，其可以最初间隔开以促进当在限定环形间隙的结构之间存在相对轴向运动时可能发生的弯曲。 段之间的间隙在相邻段之间周向地偏移以产生迷宫，流体可以通过该迷宫在相反的方向上移动，同时导致碎屑被保持。 这些节段保持弯曲状态，以在触及相邻结构的其自由端施加收缩应力。
