PROCEDURE FOR SUPPLYING MATERIAL INTO FLOW OF LIQUID MEDIUM OF HIGH PRESSURE, MECHANISM OF SUPPLY AND UNIT OF SUPPLY OF OIL FIELD MATERIAL

摘要

FIELD: oil and gas production. ^ SUBSTANCE: procedure consists in filling chamber with material of supply in first position, in essence isolated from flow of high pressure and in displacement of chamber from first position into second position open to flow of high pressure at essential shut-off of supply. Also, the chamber stays under pressure for its more active filling with material and for synchronous filling in accordance with its displacement from the first position into the second position. ^ EFFECT: raised efficiency of procedure and reliability of systems operation. ^ 25 cl, 8 dwg
