The invention discloses an encapsulated gel breaker for hydraulic fracturing of a coalbed methane well, as well as preparation and using methods thereof. The encapsulated gel breaker for hydraulic fracturing of the coalbed methane well comprises a gel breaker constituted by nonylphenol polyoxyethylene ether and a capsule wrapping the gel breaker, wherein the capsule is made of polylactic acid. The preparation method of the encapsulated gel breaker for hydraulic fracturing of the coalbed methane well comprises the following steps: preparing the gel breaker, namely nonylphenol polyoxyethylene ether into particles; and atomizing a wrapping material, namely polylactic acid, and enabling polylactic acid to meet with the gel breaker in hot air to form the capsule wrapping on the surface of the gel breaker. The using method of the encapsulated gel breaker for hydraulic fracturing of the coalbed methane well comprises the following steps: adding the encapsulated gel breaker and a fracturing proppant into a clean fracturing solution together, and then performing fracturing construction by using the clean fracturing solution. The invention provides the encapsulated gel breaker for hydraulic fracturing of the coalbed methane well, which can be matched with the clean fracturing solution containing an organic sodium salt and a cationic surfactant and get good effects, as well as the preparation and the using methods thereof.
