PRESSURE COMPENSATION MODULES FOR CORING TOOLS, CORING TOOLS INCLUDING PRESSURE COMPENSATION MODULES, AND RELATED METHODS |
摘要 |
Methods of compensating pressure differences between interiors and exteriors of inner barrels of coring tools may involve advancing a coring tool into a wellbore, the coring tool comprising an inner barrel for receiving a core sample cut by the coring tool, a first fluid being sealed within the inner barrel. A second fluid may flow along an exterior of the inner barrel. A pressure difference between the first fluid and the second fluid may be reduced. A volume occupied by the first fluid may be compressed by moving a compensating member. The volume occupied by the first fluid may be expanded by moving the compensating member. |
