Description

Technical Field

[0001] The utility model relates to the technical field of adding medicine to an oil field water system, in particular to a medicine supply device used for adding medicine to an oil field water system. Background Art

[0002] During the oilfield construction process, it is necessary to add materials to the production medium for processing. The production medium flow data is generally obtained by the main pipeline system metering data source (DCS / transmitter). The dosing tank valve supplies medicine according to the control curve set by the product, so that the descaling agent and bactericide in the production medium can be in a suitable ratio to ensure the stability of the production medium quality and the water injection sterilization effect.

[0003] The existing method of adding descaling agents and bactericides is to inject them directly into the pipeline of the production medium through two sets of pipes, and then flow with the medium. During this process, the liquid medium and the material agent cannot be effectively mixed, so the treatment quality of the medium is poor. Therefore, in order to solve the above problems, a drug supply device for adding drugs to the oilfield water system is proposed. Utility Model Content
