发明名称 Crustal core sampler and method of coring crustal core sample using the same
摘要 Disclosed herein are a crustal core sampler, by which a crustal core sample can be cored in a state coated with a flow-able coating material free of any contamination, and a method of coring a core sample using this crustal core sampler. The crustal core sampler comprises a drilling mechanism and a barrel, wherein the barrel is equipped with a flow-able coating material-ejecting mechanism, and a columnar crustal core portion is coated with a flow-able coating material. Alternatively, the crustal core sampler is constructed by a drill pipe and an inner barrel, wherein the inner barrel is equipped with an inner barrel body, a core elevator, a channel-forming member for forming a flow-able coating material-running channel and flow-able coating material-ejecting openings, and a columnar crustal core portion is coated with a flow-able coating material.
