More Information
Summary:The invention discloses a core holder, which includes: a nonmetal high pressure resistant cylinder; a core component disposed in the cylinder; a left mandrel end seat assembly and a right mandrel end seat assembly that are respectively disposed at the left end and right end of the cylinder and are connected with the left end and the right end of the core component; a ring crush cavity formed by the cylinder, the core component, and the left mandrel end seat assembly and the right mandrel end seat assembly; and a left connecting sleeve and a right connecting sleeve, with the left connecting sleeve being used for connecting the cylinder left end and the left mandrel end seat assembly, and the right connecting sleeve being used for connecting the cylinder right end and the right mandrel end seat assembly. The core holder provided by the invention is difficult to leak, can withstand higher pressure, and can better meet the experimental requirements, thereby being more conducive to oil-gas exploration and development.
