摘要： 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.

摘要： An optical element includes a porous layer with a network of a plurality of interconnected voids. The porous layer is optically diffusive to at least one wavelength of light when the network of interconnected voids is substantially free of fluid. The porous layer of the optical element undergoes a detectable optical change upon fluid ingress into the network or egress from the network of interconnected voids.

摘要： A particulate filter inspection system for a particulate filter includes a compressed air source, a primary conduit, a controller, a probe, and a gauge. The compressed air source is configured to draw air from an air source. The primary conduit is configured to receive the air from the compressed air source. The probe is coupled to the primary conduit and communicable with the controller. The probe is configured to interface with a face of the particulate filter to provide the air to only a sector of the particulate filter. The gauge is configured to determine a pressure of the air within the primary conduit when the probe is providing air to only a sector of the face of the particulate filter. The controller is configured to receive the pressure from the gauge, compare the pressure to a target upper pressure, and provide an indication that the particulate filter is dirty if the pressure is not lower than the target upper pressure.
