| description | The invention relates to the technical field of oil and gas production, in particular to a pressurizing water injection device with a chemical adding function and a use method of the pressurizing water injection device. Water injection pressure can be increased at a wellhead through use of a pressurizing water injection pump, so that injection allocation requirements of all water injection wells are met; the problems that water cannot be injected into a stratum and under-injection is serious due to insufficient injection allocation and injection pressure from a high-pressure water injection pipeline at the front end of a water injection pipe network to the tail end of a water injection well are solved. Meanwhile, the pressurizing water injection device has the function of collecting leaked liquid in the pressurizing water injection pump, medicine adding can be carried out, and the liquid after medicine adding can be reinjected into a liquid outlet pipeline to be uniformly injected into a well, so that when th |
