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.

摘要： The present invention belongs to the technical field of hydrate application, and proposes an electric field-based CO2 capture apparatus by a hydrate method and a method therefor. Small particles of hydrate are generated by incoming seawater and incoming hydrate former at low temperature and high pressure. After flowing through the electric field, the particles are quickly formed, and then separated, dried and compressed efficiently by a solid-liquid separation chamber. Finally, hydrate blocks are produced. The combination of a stirring method, a spraying method and an external electric field can effectively solve the characteristics of slow hydrate formation and long cycle. The solid-liquid separation chamber can be designed to efficiently filter out the hydrate particles and prevent a filter plate from blocking. The use of heat exchange chambers in many places make the cooling amount in the discharged waste recycled, greatly thereby improving the utilization efficiency of energy and economic benefits.

摘要： A method for enhancing geological storage by injecting nanoparticles to stabilize CO2 microbubbles, which belongs to the technical field of multiphase flow. The method first improves the physical properties of the fluid by pre-mixing CO2 and nanoparticles, and then the fluid is transported to the underground through high-pressure pipelines, and then CO2 microbubbles containing nanoparticles are generated through a dense perforated plate arranged by an injection well to improve the dissolution rate and sweep efficiency of the gas in the saline aquifer, so as to enhance the later mixing of the fluid. The combined injection can improve CO2 storage capacity and storage safety, and further reduce the risk of gas leakage in the reservoir.
