| description | The invention discloses a compressible highly flexible plugging agent, and the 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 poly anionic cellulose (PAC), 0.5-1 part of biopolymer (XC) and 10-15 parts of superfine calcium carbonate. The preparation method comprises the following steps: adding the components in the weight parts according to the common preparing method at room temperature and normal pressure into natural rubber, mixing and stirring evenly, drying and grinding to 0.05-50mm of granules. The invention is characterized by wide raw material source, scientific and simple process, safe construction, high stemming ratio, strong compressibility and high success rate of antileakage, is widely used in petroleum and geological drilling technology and is especially applicable to the application in fracture hard formation and karst type formation. |
