CORING TOOLS FOR MANAGING HYDRAULIC PROPERTIES OF DRILLING FLUID AND RELATED METHODS
摘要：
A coring bit for use on a coring tool for extracting a sample of subterranean formation from a well bore includes a bit body having a cavity, wherein a throat portion of the cavity extends into the bit body from a face of the bit body. The coring bit includes a sleeve disposed within the cavity of the bit body, the sleeve configured to separate a face discharge channel and a throat discharge channel. The face discharge channel is located radially outward of the sleeve and the throat discharge channel is located radially inward of the sleeve. A method of repairing a such a coring includes removing the sleeve from the cavity of a bit body.
摘要（中）：

用于从井眼中提取地下地层样品的取芯钻头包括具有空腔的钻头体，其中腔体的喉部从钻头体的表面延伸到钻头体内。 取芯钻头包括设置在钻头体的腔体内的套筒，该套筒构造成分离面部排出通道和喉部排放通道。 面部排出通道位于套筒的径向外侧，并且喉部排出通道位于套筒的径向内侧。 修理这种取芯的方法包括将套筒从钻头体的空腔中取出。
