PURPOSE:To prevent inadvertent outflow of soil specimen held in a sample storage tube, by making a plug body put in the tip opening of the sample storage tube contract itself with a liquid pressure to close the tip opening. CONSTITUTION:A sample storage tube 23, a plug body 24, a sand sample 27 and the like are provided. Then, an inner tube 18 sticks out of the lower end opening of an outer tube 1 to be forced into a sand soil and the sample 27 is packed and held into the storage tube 23 through the plug body 24 from the opening of a shoe 19. Subsequently, a piston 9 stops reaching the lower end of the outer tube 1 and as a through hole 10 matches a smaller diameter section 7 to form a clearance therebetween, a pressure liquid in the outer tube 1 flows between the inner tube 18 and a sampling tube 22 and further into the shoe 19 to have the pressure thereof act on the outer side of the plug body 24. Then, a rod 8 is released from the fixation and lifted slightly and the plug body 24 contracts itself inward with the pressure working on the outer surface thereof to close the lower end opening of the storage tube 23. Thus, the sample 27 can be taken positively without flowing out inadvertently.

PURPOSE: To clearly verify the vertical direction of a tubular member including a core by allowing an inner tube element used for a double tube device for taking soil samples with a different end part to make connection to a plurality of identical inner tube elements that are connected by a tube member made of a fiber-reinforced plastic. CONSTITUTION: Both end parts that can be identified being connected by a tube member made of a fiber-reinforced plastic are provided at an inner-tube element 1, and an orientation marking 2 is executed to the entire length of the tube member before covered with a plastic thin layer, thus minimizing the number of operations in a work site and clearly verifying the vertical direction of the part of the tube member including a core in all cases.

18 SPONGE LINER SLEEVES FOR A CORE BARREL ASSEMBLY, SPONGE LINERS AND RELATED METHODS EP16756367.5 2016-02-25 EP3262274A1 2018-01-03 UHLENBERG, Thomas; BRAND, Marcel
A liner tube for a core barrel assembly includes a substantially cylindrical sleeve having an inner surface configured to be coupled to a layer of material that is configured to absorb or adsorb formation fluids or parts of formation fluids. At every longitudinal location of the sleeve with respect to a longitudinal axis of the sleeve, a transverse cross-section of a wall of the sleeve may include at least one gap extending radially through the entire wall of the sleeve, such that the at least one gap separates a portion of the sleeve wall on one circumferential side of the at least one gap from another portion of the sleeve wall on an opposite circumferential side of the at least one gap. The sleeve has flexibility in a circumferential direction greater than that of a sleeve without a gap extending radially through an entire wall of the sleeve at a transverse cross-section of the sleeve at every longitudinal location of the sleeve. The sleeve may include at least two circumferential segments in contact with an elastic element extending in a circumferential direction. Methods of forming a liner for a core barrel assembly, methods of building a coring tool with such a liner, and methods of coring a formation material are also disclosed.
