Abstract
The present disclosure provides a method and equipment for searching a non-unique solution of a petrophysical property combination in history matching. The method includes: receiving field historical data, and dividing the field historical data into a tuning historical data portion, and a validation historical data portion; inputting initial data for the petrophysical property combination into an proxy model to obtain field response data; optimizing the petrophysical property combination to minimize an error between the field response data corresponding to the optimized petrophysical property combination and the field response data of the tuning historical data portion; inputting the optimized petrophysical property combination into the proxy model to obtain field response data corresponding to the optimized petrophysical property combination; matching the field response data corresponding to the optimized petrophysical property combination and the field response data of the validation historical data portion; and if the field response data corresponding to the optimized petrophysical property combination and the field response data of the validation historical data portion match e…
