FIELD: mining.
SUBSTANCE: invention relates to downhole containers with solid reagent intended for prevention of saline deposits sediment at submersible equipment. Device includes cylindrical sections with reagent, connected by couplings and having mixing chamber, separated from reagent by permeable partition and provided with holes for connection to well. Permeable partition is directed along axis of cylindrical section, made with flat or concave shape to divide its cavity into chamber filled with reagent, and mixing chamber. Within mixing chamber cylindrical section wall is equipped with top and bottom holes communicating mixing chamber to well.
EFFECT: higher reliability of container due to simplification of design and stabilisation of reagent batching into reservoir fluid.
