摘要： Methods and systems for evaluating the subterranean formation of a wellbore are provided. In one embodiment, a geographical orientation of a downhole tool relative to Earth may be determined. The downhole tool may include a coring tool positioned to extract a core sample from a formation of the Earth. The orientation of the core sample with respect to the downhole tool also may be determined. Further, based on the geographical orientation of the downhole tool and the orientation of the coring sample, a geographical orientation of the core sample with respect to the Earth may be determined.

摘要： A coring method includes disposing a coring tool in a borehole adjacent a subterranean formation to be sampled. The method further includes determining a property of the formation and selecting a coring tool operational mode based on the property of the formation. The method also includes obtaining a sample from the formation using the coring tool operational mode. A type of coring shaft also may be selected based on the property of the formation.

摘要： An example coring tool includes a cylindrical body having a leading edge to contact a substance and a cavity defined at least in part by an inner surface of the cylindrical body. The inner surface is to engage and retain a sample from the substance with a plurality of raised features. The raised features are shaped so that at least one of the raised features or an exterior surface of a sample in the cavity deforms to increase a force required to remove the sample from the cavity.

摘要： A core orientation device (10) for a core drill (12). The device (10) comprises an arrangement (14) for providing signals (16) associated with a physical orientation (18) of the core orientation device (10). Processing means (22) are provided for processing the signals (16) so as to provide processed data (23) from which a measure (24) of the physical orientation (18) of the core orientation device (10) can be established. The measure (24) is associated with the physical orientation (18) of the device (10) at a particular moment in time. A memory (26) is coupled to the processing means 22 for storing the processed data 23. To this end there is provided an interface means (27) comprising first means (28) for storing the processed data (23) in the memory (26) and second means (30) for accessing the memory (26) to provide the measure (24) of the physical orientation (18) of core orientation device (10) when required.
