摘要: A core sample of an earth formation is obtained by drilling with a coring bit and circulating fluid through the bit. The contains no mud solids for contaminating or, in alternative, mixed bulk material which invades occupies pore spaces preferentially over solids. This more readily removed from cleaning than
