FIELD: oil and gas industry.
SUBSTANCE: invention relates to oil and gas industry, in particular, to devices for neutralization of acid after acid treatment of formation. Proposed device comprises cylindrical case with outlet channel and holes to extract fluid medium from pumping equipment. Magnesium metal granules are loaded into inner cavity. Inside the housing there is a perforated empty pipe inserted through the whole length, through which the housing is interconnected with the outlet channel. From below branch pipe is communicated with well through check valve opening at certain pressure drop, allowing to operate pump equipment at optimum input loads.
EFFECT: reduced load on equipment lifting liquid, and reduced period between service of filter due to availability of through channel with valve opening at required pressure drop for connection with well.
