| titleOfInvention | A stratified gas channeling plugging process for fire-flooding production wells |
| abstract | The invention provides a layered gas channeling plugging process for fire-flooding production wells. A certain amount of gel composition is injected; (2) a certain amount of high-strength gel particles are injected from the oil pipe; (3) an inorganic sealing agent is injected to seal the channeling system, and water is injected instead, and the excess water is replaced. The layered gas channeling plugging process of the fire-flooding production well and the pipe string used in the invention solve the problems of unsatisfactory plugging effect of the original technology, complicated construction procedures, long construction time and high operation cost, and can effectively reduce the operation procedures and cost, improve the effectiveness of measures and production time. |
