  • Patent number: 11874211
    Abstract: A method and device for obtaining microscopic occurrence characteristics of oil stored in a shale, where the microscopic occurrence characteristics include the adsorbed oil film thicknesses in the shale and the oil distribution in the shale. The method includes four steps. The first step is an experiment step in which a N-Hexane vapor adsorption experiment is performed on a sample made from a shale. The second step is a first obtaining step for calculating and obtaining the adsorbed oil film thicknesses in the shale. The third step is a first calculating step and the fourth step is a second obtaining step. They aim to obtain the oil distribution in the shale.

  • Patent number: 11254746
    Abstract: An anti-human PD-1 monoclonal antibody, and a preparation method therefor and an application thereof. The anti-human PD-1 monoclonal antibody has good bioactivity, can effectively bind with an extracellular region of a human PD-1 protein receptor, and can effectively seal PD-1 protein at protein level and cellular level and block the binding of the PD-1 protein with a ligand PD-L1, thereby effectively enhancing immunity. The monoclonal antibody can be applied independently or jointly with other antitumor drugs to tumor immunotherapy and the diagnosis and screening of patients with PD-L1 positive tumors; and the monoclonal antibody has a promising prospect in the preparation of drugs for treating tumors, resisting autoimmune diseases and the like.
