  • Publication number: 20240175340
    Abstract: 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.

  • Publication number: 20240136929
    Abstract: A buck converter includes a high-side N-FET, a low-side N-FET, a P-FET, a between a gate terminal and a source terminal of the P-FET, aa capacitor, and a FET driver. The FET driver operates in a selectable one of a continuous current mode and a discontinuous current mode. In a first phase of the discontinuous current mode, a gate voltage on the gate terminal the N-FET equalizes to a source voltage on the source terminal of the N-FET to turn on the first N-FET. A high output voltage on a high-side output of the FET driver is high enough to overcome a threshold voltage of a body diode of the first P-FET to provide the high output voltage minus a threshold voltage to the gate terminal of the high-side P-FET to turn on the high-side P-FET.
