The present disclosure relates to the field of oilfield plugging agents, and in particular to a plugging agent for oil extraction in an oilfield and a preparation method therefor and an application thereof.

Plugging agent for oil extraction in oilfield and a preparation method therefor and application thereof

The present invention provides a preparation method of Beta molecular sieve, comprising: activating a mineral having low silica-to-alumina ratio and a mineral having high silica-to-alumina ratio, respectively, wherein the mineral having low silica-to-alumina ratio is activated via a sub-molten salt medium, and the mineral having high silica-to-alumina ratio is activated via means of high-temperature calcination; mixing the activated minerals with sodium chloride, potassium chloride, water and template agent for hydrothermal crystallization, wherein the charged amounts of the raw materials satisfies a molar ratio of: 0.03-0.18 NaO: 0.01-0.03 KO: 0.1-0.4 (TEA)O: 1 SiO: 0.01-0.5 AlO: 12-40 HO; cooling the crystallized product and removing the mother liquor by filtration, washing the resulting filter cake with water to neutral and drying it to obtain the Beta molecular sieve.
