摘要： A compressible and highly flexible plugging agent comprises the following components in parts by weight: 70-80 parts of natural rubber, 0.5-1 part of polyacrylamide (PAM), 1.5-3 parts of polyanionic cellulose (PAC), 0.5-1 part of biopolymer XC and 10-15 parts of ultrafine calcium carbonate; and the preparation method thereof comprises the following steps: adding the components in the weight parts into the natural rubber in order according to the common preparing method at normal temperature and pressure, mixing and stirring evenly, drying and then grinding into particles of 0.05-50 mm. The plugging agent is characterized by wide raw material sources, simple process, safe application, high plugging ratio and high compressibility, which is suitable for oil recovering and geological drilling applications.
