摘要： A downhole coring tool conveyable within a borehole extending into a subterranean formation, wherein the downhole coring tool comprises a housing, a hollow coring bit extendable from the housing, a first motor operable to rotate the coring bit, and a second motor operable to extend the coring bit into the subterranean formation through a sidewall of the borehole in a direction not substantially parallel to a longitudinal axis of the borehole proximate the downhole coring tool. A static sleeve disposed in but rotationally independent of the coring bit receives a portion of a core sample of the formation resulting from extension of the coring bit into the formation. The static sleeve comprises a protrusion extending radially inward toward the core sample sufficiently to mark the core sample.
摘要翻译： 一种井下取芯工具，其可在延伸到地层内的钻孔内传送，其中所述井下取芯工具包括壳体，可从所述壳体延伸的中空取芯钻头，可操作以使所述取芯钻头旋转的第一马达，以及第二马达， 通过钻孔的侧壁在基本上平行于靠近井下取芯工具的钻孔的纵向轴线的方向上取芯钻进地层中。 设置在旋转独立于取芯钻头的静态套筒容纳由取芯钻头延伸到地层中而形成的地层岩心样本的一部分。 静态套筒包括径向向内朝着芯样品径向延伸的突起，以足以标记芯样品。
