| titleOfInvention | Enzyme-catalyzed in-situ deep acidification fluid in oil and gas fields and its acidification method and device |
| abstract | The invention relates to the technical field of acidification production equipment, specifically an enzyme-catalyzed in-situ deep acidification solution in oil and gas fields and its acidification method and device. 15min, after mixing evenly, prepare in-situ acidification solution; then increase the pressure in the mixing tank continuously, and after 3-6 hours of reaction, fully react the organic acid ester and hydrolase; after the preparation is completed, guide it to the crack In the pore throat, the organic acid generated under the control of enzyme catalysis can effectively dissolve the carbonate and have the effect of expanding the pore throat; the production device includes a pressurized production structure and a buffer mixing structure, and the pressurized production structure The side end position is connected with a buffer mixing structure; the invention can improve the permeability of the formation in a large area, improve the acidification effect and the recovery rate of crude oil and natural gas; at the same time, the invention has simple on-site construction, strong operability and wide application range. |
