| titleOfInvention | A kind of gel ball for oil recovery with temperature resistance and salt resistance and preparation method thereof |
| abstract | The invention relates to the field of tertiary oil recovery in oil fields, and discloses a gel ball for oil recovery with temperature resistance and salt resistance and a preparation method thereof. A. The initiator A and the initiator B are dissolved in the encapsulant to obtain the solution A; 2. The solution B is prepared: the crosslinking agent B is dissolved in deionized water to obtain the solution B; 3. Under the irradiation of the ultraviolet lamp, the solution A is dropped into solution B, and after the dropwise addition is completed, the light is continued, and the gel balls with temperature resistance and salt resistance are obtained by filtration. The particle size distribution range of the gel ball for oil production with temperature resistance and salt resistance is 1~10mm, the expansion ratio of the diameter of clear water is 0.5~5 times, the surface is smooth, and in the case of adding sodium citrate, the viscoelasticity coagulates. The expansion ratio of the rubber ball increases, and the surface is in a sticky state. And through formula adjustment, the gel balls for oil recovery with various properties can be prepared, so as to improve the practicability and applicability of the method. |
