Combining module PVTi with E300 in ECLIPSE, we found the 3D and three phases simulating module of special low permeability reservoirs in YSL Oilfield. On the basis of history matching, considering gas injection volume, slug size, gas/water ratio, the speeding of gas injection, injection rate of sequent water flooding in water alternating gas, taking the volume of increasing oil and oil-draining rate as evaluation criterion we proceed orthogonal test design according to the principle orthogonal experimental design. By means of intuitive analysis and variance analysis to the test results, getting the primary and secondary orders that injection parameters effect evaluation criterion and optimizing best combination scheme of water alternating gas injection parameters for offering theoretical direction and technical support to water alternating gas injection parameters optimization in spot CO2 displacement. |
