The application provides a hydrolysis acidification equipment for straw treatment, and relates to the technical field of straw hydrolysis, which comprises an equipment main body and multiple layers of sieve plates, wherein the sieve plates are all arranged in a conical shape, the sieve holes of the upper sieve plate are larger than those of the lower sieve plate, and stirring rods are movably installed on the upper sides of the sieve plates. The equipment main body is divided into multiple acidification zones from top to bottom, different sizes of straws are screened layer by layer through the multiple layers of sieve plates, and fall into different acidification zones respectively, and acidification bacteria liquid enters the equipment main body to hydrolyze and acidify the straws. The multiple acidification zones are formed through the multiple layers of sieve plates, the straw hydrolysis and acidification effect is effectively improved, the wedged extrusion space formed between the cutting edges of the scraper and the inclined part of the auxiliary knife is used to crush the straws, and the crushing effect of the straws is improved.

This invention provides a wellbore nitrogen atomization acidizing system and method, belonging to the field of reservoir stimulation technology. The system includes: an atomization unit with an atomization outlet located inside the wellbore for generating initial acid in an atomized state; an acid recovery unit equipped with an acid recovery pump for recovering acid and obtaining a mixed acid solution; a separation unit for separating the mixed acid solution to obtain the initial acid solution and injecting it into the atomization unit; a control unit for determining an acid distribution scheme based on real-time acidizing status information, generating a corresponding acid supply command based on the scheme, and distributing the command to the acid supply unit; and an acid supply unit connected to the inlet of the atomization unit for supplying the initial acid solution to the atomization unit based on the acid supply command. This invention effectively improves acidizing performance, reduces acid loss, and is adaptable to complex wellbore environments.

The application provides an injection well fluid and a preparation method and application thereof, the injection well fluid comprising a solvent and graphene oxide, the pH of the injection well fluid being 3-6; in the injection well fluid, the mass concentration of the graphene oxide is 0.2 mg / mL-5 mg / mL.
