Abstract
A core holder and a prediction method for starting pressure gradient of shale oil based on the core hold are provided. The core holder includes an inlet plug, an outlet plug, a core accommodating cavity disposed between the inlet plug and the outlet plug and used for accommodating the shale oil, a rubber gasket disposed between the outlet plug and the core accommodating cavity, and a microinjector including a microinjector needle portion that passes through the outlet plug and the rubber gasket in sequence to be in contact with the shale oil in the core accommodating cavity. The core holder and the method can solve problems that movable oil volume of a low-porosity, low-permeability and small-volume rock sample and a shale rock sample cannot be accurately measured, and that a movable scale and a starting pressure gradient of the shale oil cannot be measured.
