摘要： A method, system and apparatus for testing properties of a rock formation surrounding a wellbore in situ. The apparatus includes a tool body, one or more indenters, and one or more acoustic sensors. The body includes an outer surface that defines one or more cavities therein. Each cavity extends into the body. Each indenter is positioned within a corresponding cavity and is positionable into an operating position and a non-operating position. The acoustic sensor is positioned within the cavity and adjacent to the indenter. The indenter is positioned at least partially beyond the outer surface when in the operating position. The acoustic sensor senses one or more acoustic events occurring when the indenter is in the operating position. The apparatus is inserted into the wellbore. Once inserted, the indenter applies a load onto the rock formation causing cracking and the sensor receives the generated acoustic transmissions. The transmissions are analyzed.
摘要翻译： 一种用于测试原位于井筒周围的岩层性质的方法，系统和装置。 该装置包括工具主体，一个或多个压头以及一个或多个声学传感器。 主体包括在其中限定一个或多个空腔的外表面。 每个腔都延伸到体内。 每个压头都位于相应的腔内，并可定位在操作位置和非操作位置。 声学传感器位于腔体内并且邻近压头。 当处于操作位置时，压头至少部分地位于外表面之外。 声学传感器感测当压头处于操作位置时发生的一个或多个声学事件。 将设备插入井眼。 一旦插入，压头将压力施加到岩层上，引起裂纹，并且传感器接收所产生的声传播。 分析传输。

摘要： An apparatus that includes one or more machined high-angle sockets and method for fabricating such sockets. The apparatus includes a body, one or more blades extending outwardly from the body, and one or more high-angle nozzles machined into a portion of the blade. The body includes a bit face at one end and a plenum formed therein communicably coupled to an opening formed at an opposing end. Each blade includes a leading section, a trailing section, a face section extending from one end of the leading section to an end of the trailing section, and an inner section extending from an opposing end of the leading section to an opposing end of the trailing section. Each nozzle includes a nozzle socket cavity and a second hole intersecting with the nozzle socket cavity and extending to the plenum, which collectively form a passage extending from the plenum to the bit face.
