Abstract: 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.

Abstract: The present invention provides a carbon dioxide ocean liquid balloon storage method. The method comprises: suspending an uncharged liquid balloon device in seawater at a depth of not less than 600 m in advance; conveying liquid carbon dioxide to an inside of the liquid balloon device through a conveying pipe; when the liquid carbon dioxide charging volume reaches the rated charging volume of a carbon dioxide submarine storage device, stopping charging; closing a stop valve of a liquid balloon inlet pipe and disconnecting the carbon dioxide conveying pipe from the liquid balloon inlet pipe; and controlling the liquid balloon device to enable the liquid balloon device to be placed in a seabed at the appropriate depth, with the depth of the seabed of not less than 3,000 m. The whole liquid balloon device is of a frame liquid balloon structure, and comprises a frame structure and a liquid balloon structure.

Abstract: The present invention discloses an electric heating thermal management system for an oil and gas transportation pipeline based on renewable energy and CO2 energy storage. It transmits the feedback data value through a data collection device arranged in the pipeline to the early warning device by the control device. After analysis and processing, the early warning device can feed back the data value to the control device and the remote operation device in two modes. Different degrees of heating amount can be generated for the oil and gas transportation pipelines at different positions in different modes. Hierarchical and distributed management control for the oil and gas transportation pipelines can be targetedly conducted in unblocked, easily blocked and blocked positions of the oil and gas transportation pipeline. The present invention couples the renewable energy electricity supply device and the CO2 energy storage device.
