Publication number: 20240175340Abstract: The present disclosure relates to a method and system for predicting a time-varying principle of waterflooding oil reservoir formation parameters. Firstly, a T2 spectrum-pore size relation model is built according to a measured pore size distribution curve and a measured T2 spectrum. A T2 spectrum of a rock sample at different water injection amounts during a waterflooding physical simulation experiment is acquired. The acquired T2 spectrum at different water injection amounts is then converted into a pore size distribution at different water injection amounts, and a pore network model at different water injection amounts is built with the pore size distribution. Oil-water two-phase flow simulation is performed, and a corresponding oil-water two-phase relative permeability curve of the rock sample at different pore volume (PV) multiples is obtained eventually. The oil-water two-phase relative permeability curve is the formation parameters in the waterflooding oil reservoir.Type: ApplicationFiled: July 26, 2023Publication date: May 30, 2024Inventors: Sen WANG, Kun WANG, Qihong FENG, Shunming LI, Yijing DU, Zheng WU, Xiang WANG, Jiyuan ZHANG, Xianmin ZHANG
