As a result, the recovery efficiency of the oil and gas well is continuously reduced, and the development of oil and gas is affected. In the case of sandstone, cementing agent and mudstone-based reservoir, as the crude oil of the stratum is continuously mined, the pressure and temperature of the stratum are changed, a sudden drop zone of a pressure drop funnel is formed in the near-wellbore zone, the crystallization and precipitation of inorganic salts and organic matters in the oil layer are enhanced, calcium and magnesium ions in water are deposited in the well, and the calcium and magnesium ions are reserved in the middle of rock formation gaps of the reservoir in the form of calcium (magnesium) carbonate crystals, so that the rock formation gaps, perforation tunnels, wellbores and the like in the near-wellbore zone are blocked.
