METHOD OF SUPPLY OF LIQUID AND SOLID REAGENTS AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2008 - IPC E21B37/06 

Abstract RU 2342519 C2

FIELD: oil and gas industry.

SUBSTANCE: invention refers to oil production, particularly to methods of supply of reagents into well or surface oil producing equipment. When implementing the method a device with reagent is arranged in a borehole of the well or in the interior space of pipes of surface oil producing equipment, and the reagent is dissolved with produced fluid penetrating into the device. The device is made in form of a chamber container connected with lifting pipes or interior space of pipes; the chamber container consists of several hollow cylinders with apertures hydraulically connected with the well or with the interior pipe space. The device performs measured supply of liquid and/or solid reagents. The container consists of chambers successively connected at the ends; a filter or filters are installed in each chamber; said filters operate as primary measuring devices. Chambers are filled with reagents. Hydraulically the chambers are connected with interior space of the well or with interior space of the pipes via apertures located in a capacity of primary mixing which is formed between the filter and a blind plug.

EFFECT: upgraded efficiency of reagents effect.
