Microaccumulator for measurement of fluid volume changes under pressure |
摘要 |
A microaccumulator for receiving and holding fluid under pressure, and for measuring fluid volume changes in one aspect in very small amounts, and for indicating the amount, the microaccumulator having a body with an interior cavity for receiving the fluid and a piston movably disposed therein which moves in response to a change in fluid amount, the piston having a sensor interconnectible with a monitor and/or system control (e.g. a computer) which can control monitor and/or record changes in the amount of fluid. A triaxial test apparatus for low permeability rock (e.g. shales) using such a microaccumulator. Methods for triaxial tests and for the use of such devices.
