  • Patent number: 12680438
    Abstract: A fracturing fluid pad fluid is applicable to a calcium-rich reservoir and composed of clear water, phosphate, pH regulator and Ca2+ chelator, wherein, for 100 weight parts of clear water, the content of the phosphate is 1 to 10 weight parts, the volume molar concentration of the pH regulator is 1 to 5 mol/L, and the volume molar concentration of the Ca2+ chelator is 0.001 to 1 mol/L; the pH regulator is urea, ammonia water, propanamide and the like, and the Ca2+ chelator is EDTA and glutamic acid and the like. The present disclosure increases the average particle size of the proppant particles generated by hydrothermal reaction of formation minerals, thereby improving its propping effect in the formation micro-fractures.
