  • Patent number: 11401223
    Abstract: The solid composite stabilizer for PCE includes the following components in parts by weight: 10 to 30 parts of a phenol-substituted ion-exchange resin, 50 to 80 parts of a basic anion-exchange resin, and 50 to 100 parts of a desiccating agent. The phenol-substituted ion-exchange resin is chloromethylated macroporous polystyrene-divinylbenzene (PS-DVB) substituted by a phenolic compound; and the basic anion-exchange resin is chloromethylated macroporous PS-DVB substituted by an amine compound. The preparation method includes the following step: thoroughly mixing the phenol-substituted ion-exchange resin, the basic anion-exchange resin, and the desiccating agent in a specified ratio to obtain the solid composite stabilizer for PCE. The solid composite stabilizer for PCE is packaged in a glass fiber bag and placed in PCE for storage and use.

  • Patent number: 10739479
    Abstract: The present application relates to geophysical survey, particularly provides an inversion velocity model, a method for establishing the same and a method for acquiring images of underground structure. The method for establishing inversion velocity model comprises: converting observation seismic records into first intermediary data which contains data with frequency no higher than a first predetermined frequency; calculating synthetic seismic records based on a set initial velocity model and converting the synthetic seismic records into second intermediary data which also contains data with frequency no higher than the first predetermined frequency; establishing an objective function based on the first intermediary data and the second intermediary data; calculating a velocity gradient of seismic wave based on the objective function; calculating a iteration step of the velocity gradient; determining the inversion velocity model based on the velocity gradient and the iteration step.
