POLYGLYCOLIC ACID RESIN SHORT FIBERS AND WELL TREATMENT FLUID |
| 摘要 |
PGA short fibers having the following characteristics of (a) to (c): (a) strength of 1 to 20 gf/D; (b) a mass loss of at least 10% after 14 days in water at a temperature of 60° C.; and (c) a pH of 1 to 5 after 3 days in water at a temperature of 60° C. with a solid content concentration of 2 mass %. The PGA short fibers preferably further having (d1) an outside diameter of 1 to 120 μm, (e1) a fiber length of 2 to 30 mm, and (f1) a fineness of 0.1 to 25 D, or the PGA short fibers preferably further having (d2) an outside diameter of 1 to 200 μm, (e2) a fiber length of less than 2 mm, and (f2) an aspect ratio of 2 to 1,200. Also, a well treatment fluid containing the PGA short fibers. |
