  • Patent number: 12012832
    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.

    Abstract: Aspects of the disclosure provide methods and apparatuses for video encoding. In some examples, an apparatus includes processing circuitry that identifies a reference sub-block in a previously reconstructed block of a picture. The processing circuitry determines whether reconstructed samples of the reference sub-block are included in an intra block copy search range according to a position of a current sub-block in a current block of the picture. The processing circuitry determines whether the reference sub-block is valid based on the reconstructed samples of the reference sub-block being determined as included in the intra block copy search range according to the position of the current sub-block. The processing circuitry further encodes the current sub-block based on the reconstructed samples of the reference sub-block in response to the reference sub-block being determined as valid.

  • Patent number: 12010316
    Abstract: One or more intra mode predictors of a current block are determined, where the one or more intra mode predictors are derived based on the neighboring samples of the current block via either a decoder side intra mode derivation (DIMD) or a template-based intra mode derivation (TIMD). Whether a position dependent intra prediction combination (PDPC) is to be applied is determined based on the one or more intra mode predictors. In response to the determining that the PDPC is to be applied, a fusion process is performed on the one or more intra mode predictors to combine the one or more intra mode predictors into a single intra mode predictor. The PDPC is applied based on the single intra mode predictor to generate a modified predictor of the current block. The current block is reconstructed based on the modified predictor generated by the PDPC.
