Latest Patents

One of Zhang's notable patents is titled "Ternary water control and gas recovery method suitable for unconsolidated siltstone gas reservoir." This patent outlines a comprehensive approach that includes several key steps. First, a silt control screen pipe, manufactured through interface hydrophobic modification, is run into a wellbore to achieve 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, which performs hydrophobic modification on the gas reservoir seepage channel surface. This process aims to achieve in-situ water blocking and silt migration, followed by a closure of the well for a preset time before exploitation.
