| titleOfInvention | A kind of oil field microcapsule non-acid autogenous heat blocking agent and preparation method thereof |
| abstract | The invention relates to an oil field microcapsule non-acid self-generated heat blocking agent and a preparation method thereof. The thermal blocking agent comprises a water-soluble microcapsule blocking agent KR-100A and a water-soluble microcapsule blocking agent KR-100B. The mass ratio of the microcapsule blocking agent KR-100A and the water-soluble microcapsule blocking agent KR-100B is: 0.9-2.1:1; the water-soluble microcapsule blocking agent KR-100A is composed of ammonium chloride, potassium chloride, Solid paraffin, polyvinyl alcohol and dimethyl sulfoxide; be made of. The present invention ensures that the content of the capsule core breaks through the capsule wall under appropriate conditions, reacts, releases heat, generates gas and cooperates with other auxiliary agents outside the capsule wall under the trigger of an external catalyst to clean and unblock. |
