Abstract: Systems, devices, and methods for estimating a value of a parameter of interest of an earth formation intersected by a borehole. Methods include conveying a carrier in the borehole having disposed thereon an acoustic imaging tool including at least one convex linear phased array module, each of the at least one module comprising a rigid shell forming a compartment containing a piezoelectric component array; using the acoustic imaging tool to take acoustic measurements of the borehole; and using the acoustic measurements to estimate at least one parameter of interest. Each module may be self-contained. The tool may include a plurality of modules circumferentially arrayed about a portion of the acoustic tool. Methods include individually removing one selected module from the acoustic tool. Methods may include selecting an outer tool diameter the same as an inner borehole diameter borehole and selecting a maximum number of modules fitting the outer tool diameter.

Abstract: An apparatus for use in a borehole may include a rotor having at least one set of magnetic elements and a cylindrical stator having a winding flowing current in a direction transverse to a long axis of the stator. The polarity of each magnetic element of the rotor may be arranged to alternate along a long axis of the rotor. The stator may be in sliding engagement with the rotor and have a core formed at least partially of laminations aligned along a plane co-planar with the long axis of the stator. Energizing the winding principally causes relative sliding between the rotor and the stator. A method for performing an operation in a borehole includes forming a well tool having at least one linear motor as described above, conveying the linear motor into the borehole, and operating a well tool by activating the linear motor.

Abstract translation: 在钻孔中使用的装置可以包括具有至少一组磁性元件的转子和具有横向于定子长轴方向的绕组的圆柱形定子。 转子的每个磁性元件的极性可以被布置成沿着转子的长轴交替。 定子可以与转子滑动接合，并且具有至少部分地由与定子的长轴共面的平面排列的叠片形成的芯。 绕组的通电主要是导致转子和定子之间的相对滑动。 一种在钻孔中进行操作的方法包括形成具有如上所述的至少一个线性马达的井具，将线性马达输送到钻孔中，以及通过启动线性马达来操作井工具。
