In porous clastic rocks, the uneven distribution of high-pressure fluid will cause changes in water saturation and frequent changes in wavelength. The purpose of this article is to study the effect of high-pressure fluid on the competence of porous clastic rocks. First, according to the dynamic high pressure technology of the two-stage light gas gun and the compressed gas target technology, the principle of dynamic high pressure loading is introduced and the rock competence in the rheological process is analyzed. The traditional Gassmann equation is adjusted to match the temperature to verify the fluid mechanism model of the porous medium. The impact of high-pressure jet on the rock surface of porous clastic rock and the influence factors of high-pressure pulse jet on rock are discussed. The experimental results show that the rock damage effect is better when the distance between adjacent pulsed jets is 9mm.
