Zusammenfassung:The invention discloses an acid fracturing method, electronic equipment and a medium. The method comprises the following steps: pre-treating a key component before acid fracturing; auxiliary fracturing is carried out through a liquid CO2 fracturing device for fracturing; embrittlement increasing and pressure reducing are conducted through preposed liquid CO2, and acid fracturing is completed. According to the method, film coating treatment is conducted on the shaft and key pipe valves in the early stage, auxiliary fracturing is conducted through the liquid CO2 fracturing device, and liquid CO2 and low-viscosity slickwater are arranged in front, so that the purposes of reducing the fracturing pressure and the construction pressure and ensuring the safety of the shaft during low-displacement long-time acid fracturing are achieved, and then the fracturing transformation effect is improved. 本申请公开了一种酸压方法、电子设备及介质。该方法可以包括:在酸压前针对关键部件进行预处理;通过压裂用液态CO2致裂器进行辅助致裂;通过前置液态CO2进行增脆、降压,完成酸压。本发明通过前期井筒及关键管阀件覆膜处理、液态CO2致裂器进行辅助致裂及前置
