Title:
DESIGN METHOD FOR SVE PROCESS PARAMETERS IN PETROLEUM CONTAMINATION SITE
Document Type and Number:
WIPO Patent Application WO/2021/142895
Kind Code:
A1
Abstract:
A design method for SVE process parameters in a petroleum contamination site, comprising the following steps: step I, determining a site and a petroleum contamination condition; step II, by combining site parameters, contamination parameters, and SVE process parameters, establishing a repair model of TOUGH software about SVE, and obtaining a repair rate y; step III, using a grey correlation degree method to select p main control factors; step IV, using the selected p main control factors to establish a multiple linear regression equation; step V, performing fitting verification on a simulation result that is based on the multiple linear regression equation, and determining whether the simulation accuracy thereof satisfies a design requirement; and step VI, selecting an optimal SVE process parameter combination and applying same. By means of the design of a typical site and multi-factor variables in combination with TOUGH simulation, the movement rules of a contaminant in a site under different scenes can be clarified, thereby facilitating the parameter design and selection of an SVE process; the main control factors are found according to the grey correlation degree method, thereby facilitating key design when performing contamination treatment; and by establishing the multiple linear regression equation, the method is more applicable to similar sites.
