| description | The invention discloses a titanium alloy oil well pipe resistant to corrosion of hydrochloric acid and hydrofluoric acid and a processing method, which are used in high-sulfur-content oil and gas wells and oil and gas wells containing acidic corrosive media, meet the requirements of corrosion resistance and wear resistance, and also meet the requirements of acid fracturing and yield increasing operation in the oil and gas wells. The hydrochloric acid and hydrofluoric acid corrosion resistant titanium alloy oil well pipe comprises a titanium alloy oil well pipe base pipe, a titanium alloy oil well pipe leached metal layer, a base pipe inner hole alloy layer with main corrosion resistance and auxiliary wear resistance, a base pipe outer circle alloy layer with main wear resistance and auxiliary corrosion resistance, and a titanium alloy oil well pipe inner and outer corrosion-resistant and wear-resistant alloy layer leakage point plugging layer. The titanium alloy oil well pipe is internally and externally prov |
