The invention relates to the technical field of fracturing technologies implemented in petroleum extraction, and discloses a hydraulic oscillation fracturing technology for oil and gas wells. The hydraulic oscillation fracturing technology is characterized by at least comprising steps of 1), perforating fracturing modification target strata of the oil wells or the gas wells; 2), selectively utilizing compressible fluid as fracturing fluid and injecting the fracturing fluid in the target strata by the aid of phi88.9mm oil pipes with the displacement higher than 4.0m<3>/min; 3), injecting a certain quantity of fracturing fluid in a front fluid injection procedure after each stratum is fractured, then quickly stopping pumps, waiting for 30-60s after the pumps are stopped, repeatedly quickly stopping the pumps by 3-5 times in an integral front fluid injection stage, and sequentially increasing consumption of the fracturing fluid. The hydraulic oscillation fracturing technology has the advantages that the post-fracturing yields of the reservoir strata can be increased by the aid of the technology, a longitudinal complete penetration effect can be realized in longitudinal strong heterogenous reservoir stratum fracturing operation, and micro-fractures can be greatly opened in the micro-fracture developed reservoir strata.
