And the experiment such as reservoir sensitivity evaluation.
Wherein steady state method oil/water, the main theoretical basis of the reform of Chinese economic structure that gas water surveys relative permeability is theoretical for one-dimensional darcy flow,
And it is to ignore capillary pressure and Action of Gravity Field, it is assumed that two phase flow is immiscible and incompressible.In total flow during experiment
Under conditions of constant, constant speed is injected in rock core simultaneously by a certain percentage for oil, water, when import and export pressure and oil, water-carrying capacity are stable
When, rock core water containing saturability no longer changes, and now oil, distribution of the water in rock core space are uniform, reach stable state,
Oil, the effective permeability of water are constants.Therefore using measure rock core import and export pressure and oil, water-carrying capacity, by Darcy's law
Oil, water effective permeability and the steady-state permeation rate value in rock core are calculated, it is average accordingly aqueous to calculate rock core with weight method
Saturation degree.Pass through and change oil, water injects ratio, it is possible to a series of oil under different water cut saturation degrees, water penetration rate value are obtained,
And thus draw out the oil of rock core, water permeability saturation curve figure.
Wherein cold store enclosure oil/water, gas water, gas/oil relative permeability measure is with Buckley-Leverett one-dimensional two
Based on phase oil-water displacement front promotes theory, and it is to ignore capillary pressure and Action of Gravity Field.Assuming that two phase flow is can not be mutual
Molten and incompressible, oil, water saturation are uniform in any section of rock core.By rock core a kind of saturated with fluid, use during experiment
One other fluid carries out displacement, and during water drive oil, oil, distribution of the water saturation in porous media are away from discrete time
Function, this process claim unstable process.According to the requirement of simulated conditions, constant-pressure drop or constant speedpump water are carried out in reservoir cores
Oil displacement experiment, measure the quality of every kind of fluid in the rock core port of export and the pressure difference at rock core both ends changes with time value, with " JBN "
Oil/water, gas water, gas/oil relative permeability is calculated in method, and draws oil/water, and gas water, gas/oil relative permeability is with containing
The graph of relation of water saturation.
