BENCH FOR MODELLING OF SALT DEPOSIT PROCESS IN GAS WELLS Russian patent published in 1994 - IPC

FIELD: geology. SUBSTANCE: bench is intended for experimental studies under laboratory conditions of salt deposit process in face zone of seam and in equipment of gas wells. For modelling of process of salt deposit in face zone of seam bench has mock-up of seam in the form of high-pressure chamber. Chamber is formed with upper and lower covers with gaskets. Inner space of chamber is divided into upper and lower subspaces with partition with perforated holes. Both subspaces have packings simulating seam of natural core material. Upper cover has inlet ducts, lower cover has duct to monitor face pressure communicating through perforated holes with lower space. EFFECT: increased reliability of experimental studies. 2 dwg
