A low temperature fracturing fluid gel breaking agent preparation method, the method includes the use of the principle of oxidation reduction using ammonium persulfate as oxidant, sodium sulfite as a reductant and activity of sulfate and sulfuric acid to produce the gel breaking agent is added to the crosslinking agent injected into thestratum, the breaker can be lower than 50 DEG C in formation temperature, the sugar aqueous polymerfracturing fluid gel completely hydrated gel breaking, solves the problem of conventional oxidation agentbreaking agent at low temperature is difficult to break, because the invention has simple preparation method, the reservoir will cause two damage and at normal temperature can be formulated to achieve the advantages,therefore, can be widely used in oil well fracturing in low temperature.
