The longitudinal position of an inner barrel within a core barrel assembly (10) can be adjusted and locked in the field without necessitating the disassembly of the cartridge cap assembly (34) within the core barrel tool (10), and therefore without entailing loss of expensive rig time. The inner tube (72) is coupled through a swivel assembly (52) to a cartridge cap (34). The cartridge cap (34) is threadedly coupled to the coring tool (10), and in particular to the outer tube (16). Thus, the cartridge cap (34) is arranged and configured to be rotated, and thus longitudinally adjusted with respect to the outer tube (16). An upper portion of the cartridge cap (34) is provided with a plurality of radially expanding fingers (50). A jam nut (48) is disposed within a cylindrical array formed by the fingers (50), and is threadably engaged with the inside surface of the fingers (50). The jam nut (48) has a frustoconical shape, and thus as the jam nut (48) is advanced longitudinally with respekt to the fingers (50), the fingers (50) are urgend outwardly, ultimately in a tight and locking contact with an interior surface of the coring tool (10). A hollow cylindrical wrench (102) is disposed throught the end of the core barrel (12) to engage the cartridge cap (34) and rotate it to the desired longitudinal position. A jam nut wrench (110) is disposed through the hollow cartridge cap wrench (102), and when the inner tube (72) has been appropriately adjusted is used to advance the jam nut (48) downwardly in the fingers (50) to expand the fingers (50) and thus lock the longitudinal position of the cartridge cap (34). |

A device in core drilling for indicating when a core barrel placed in a rotatable hollow drill rod is no longer capable of receiving a further quantity of reamed-out core material includes a valve which at said condition of the barrel constricts the passage for flushing medium flowing between the core barrel and the bore of the drill rod so that a readable flushing medium pressure increase occurs. The valve closes off said passge incompletely to allow a minor quantity of flushing medium to be taken to the drill bit mounted at the bottom of the drill rod, thereby to prevent said drill bit from being burnt out. |

The method includes obtaining measured core sample data of a core sample retrieved from the formation, the core sample data measured by injecting fluid into the core sample, obtaining a digital rock model of the core sample describing a physical pore structure in the core sample, and obtaining a fluid model describing a physical property of the fluid. A digital core analysis (DCA) of the core sample is performed to generate a DCA simulation result and the DCA is tuned using the measured core sample data to reduce a difference between the DCA simulation result and the measured core sample data. The tuning is performed by adjusting, in response to the difference exceeding a pre-determined limit, a parameter of the DCA to generate an adjusted parameter and further performing the DCA to reduce the difference. | ||||||
