This invention belongs to the field of gas reservoir development technology, specifically relating to a method for constructing a gas channeling identification chart for condensate gas reservoir injection development. The method includes: screening five gas channeling discrimination indicators for production wells during the cyclic gas injection development process of condensate gas reservoirs; performing data standardization and quality control on the five screened gas channeling discrimination indicators to eliminate random errors; constructing a radar chart using the processed five gas channeling discrimination indicators to quantitatively determine the gas channeling stage; screening five gas channeling discrimination indicators for production wells in the current stage, and projecting the obtained gas channeling discrimination indicators onto the gas channeling identification chart to determine the degree of gas channeling in the current stage of production wells. The method provided by this invention can be used for on-site guidance of gas channeling early warning and discrimination in the later stages of condensate gas reservoir injection development, helping to formulate targeted prevention and control strategies. As an effective method for gas channeling early warning and evaluation of the degree of gas channeling in condensate gas reservoir injection development, the method provided by this invention has broad prospects for widespread application.

This invention provides a method, system, storage medium, and terminal for identifying energy-neutral atom source regions. The method includes acquiring the ephemeris of a deep-space spacecraft in a geocentric solar ecliptic coordinate system; acquiring the field of view of an energy-neutral atom imaging unit within the deep-space spacecraft; acquiring the ephemeris of the Sun and Jupiter in a J2000-level ecliptic celestial reference system centered on the deep-space spacecraft; acquiring the position of the magnetopause in the geocentric solar ecliptic coordinate system; acquiring the coverage area of ​​the magnetopause in the J2000-level ecliptic celestial reference system centered on the deep-space spacecraft; and determining the source region of the energy-neutral atoms based on the field of view of the energy-neutral atom imaging unit, the coverage area of ​​the magnetopause, and the ephemeris of the Sun and Jupiter. The energy-neutral atom source region identification method, system, storage medium, and terminal of this invention can distinguish between energy-neutral atoms from background interstellar sources, the foreground Earth's magnetosphere, and other source regions, offering speed, accuracy, and strong practicality.
