摘要： The present disclosure provides a method for preparing a self-floating transparent nano ultrathin film. According to the present disclosure, the MXene film layer and the nano ultrathin film layer are sequentially subjected to suction filtration on the substrate material by utilizing a vacuum suction filtration technology, and thus a double-film structure is loaded on the substrate material; then an oxidant is subjected to oxidizing and bubbling on the MXene film layer in a permeation way, and thus the substrate material and the nano ultrathin film layer can be separated in a physical isolating manner. Finally, the nano ultrathin film is completely separated in a liquid phase floating separation manner. The nano ultrathin film prepared by the method provided by the present disclosure has a specific thickness and light transmittance through different loading capacities, and the substrate material can be repeatedly utilized.

摘要： A carbon dioxide sequestration method based on reservoir wettability optimization design and layered regulation, which proposes the following four schemes for a carbon dioxide sequestration process: a carbon dioxide sequestration process seepage characteristics simulation scheme, a reservoir wettability optimization design scheme, a reservoir wettability regulation scheme and a carbon dioxide sequestration well layout design scheme. Firstly, a quantitative relation between the contact angle and the carbon dioxide seepage characteristics of a reservoir is obtained by relevant methods, a large scale simulator is used to quantitatively simulate the influence of the contact angle distribution of the reservoir on carbon dioxide sequestration, and layered optimization design and regulation of reservoir wettability are carried out according to the simulation results; and a well layout mode of “using one well for multiple purposes—using two wells in conjunction—adopting a network layout” is used to improve the flexibility of well layout.
