  • Patent number: 11938416
    Abstract: Disclosed in the present invention is a polyether polyol refining method, comprising (1) neutralising or diluting crude polyether polyol to obtain a mixed solution; (2) flowing the mixed solution through a hydrophilic medium to aggregate same into a first density phase liquid and a second density phase liquid, the first density phase liquid being an aqueous solution containing alkaline metal ions and/or alkaline earth metal ions, and the second density phase liquid being polyether polyol; and (3) allowing the first density phase liquid to settle and separating same from the second density phase liquid to obtain refined polyether polyol. In the present refining method, using the hydrophilic medium for one-step removal of the alkaline ions and water in the polyether polyol simplifies the treatment steps, increases treatment efficiency, and can prevent polyether polyol loss; the obtained polyether polyol has low alkaline ion content and little odour.

  • Publication number: 20240094419
    Abstract: A seismic quantitative prediction method for shale total organic carbon (TOC) based on sensitive parameter volumes is as follows. A target stratum for a TOC content to be measured is determined, logging curves with high correlations with TOC contents are analyzed, the logging curves are found as sensitive parameters; sample data are constructed using the sensitive parameters; a radial basis function (RBF) neural network is trained with the sample data as an input and the TOC content at a depth corresponding to the sample data as an output to obtain a RBF neural network prediction model; sensitive parameter volumes are obtained by using the sensitive parameters and post stack three-dimension seismic data to invert; prediction samples are constructed using the sensitive parameter volumes; the predicted samples are input to the RBF neural network prediction model to calculate corresponding TOC values, thereby the TOC content of the target stratum is predicted.
