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: A distributed low energy dynamic thermal management system for solid matter prevention and control in oil and gas transportation pipeline includes pipeline data monitoring terminal, current and electric pulse control terminal, land console, electric heating terminal, wiring flange, oil and gas transportation pipeline, valve structure. The system monitors the state of the pipeline in real time by the pipeline data monitoring terminal, and transmits the monitoring data to the current and electric pulse control terminal in real time, the current and electric pulse control terminal produces different thermal responses to the electric heating terminal according to the state in the tube, raises the temperature inside the tube by generating a continuous current, unblocks pipeline by generating high power electric pulse, so as to realize real-time monitoring and local temperature dynamic control of oil and gas transportation pipeline.
