Latest Patents

Dunyuan Yu holds a patent titled "Ternary water control and gas recovery method suitable for unconsolidated siltstone gas reservoir." This patent outlines a comprehensive method that includes several key steps. First, a silt control screen pipe, manufactured through interface hydrophobic modification, is run into a wellbore to achieve effective water and silt control. Second, a surface hydrophobic modified gravel is filled in the annular space between the silt control screen pipe and the wellbore, forming a hydrophobic gravel packing layer. Third, a wetting agent aqueous solution is injected into the stratum, performing hydrophobic modification on the gas reservoir seepage channel surface. This process enables in-situ water blocking and silt migration, followed by a well closure for a preset time before exploitation. Dunyuan Yu's innovative approach is encapsulated in this single patent, which showcases his expertise in the field.
