| titleOfInvention | Divering agent and method of closing cracks in wells using this |
| abstract | The diverting agent of the present invention contains a polyvinyl alcohol-based resin, and a diverting agent is added to a 0.48% by mass aqueous solution of guar gum to prepare a mixed solution having a concentration of 12% by mass, and the mixed solution is 60 at 30 ° C. The dispersion obtained by dispersing for a minute is pressure-dehydrated at a pressure of 1 MPa using a pressure dehydrator equipped with a drainage portion having a slit having a width of 2 mm, and the square root x of time is integrated on the vertical axis on the vertical axis. Equation (A): y = ax + b (in equation (A), y is the cumulative dehydration amount (g), x is the time elapsed from the start of pressurization) from the scatter plot plotted on the graph with the amount of dehydration y. The square roots, a and b of (minute) represent the slope and intercept of the regression line, and when the regression line represented by 0 <x≤2) is calculated, the slope a of the equation (A) is the condition (B). : Satisfy a ≦ 80. |
