Carbon dioxide drives well killing fluid gas and invades simulation evaluation experimental apparatus

摘要: The utility model relates to an oil recovery engineering technical field belongs a carbon dioxide drives well killing fluid gas and invades simulation evaluation experimental apparatus very much. provides can't drive the problem that performance was invaded at under high temperature pressure condition, it is by cylinder 1, sensor 2, air -vent valve 3, rock core holder 4, check 5, sealing joint 6, wellbore hole 7, water bath 8, sample thief 9, backpressure 10, intermediate receptacle 11, liquid feeding device 12, trap 13, control system 14, ISCO pump 15, conservancy booster 16, mechanical table 17 portable base 18 constituteed, 7 polycarbonate PC stick transparent, withstand voltage, resistant. has advantages of structure exquisite, convenient operation, can directly perceivedly present kill -job in -process invade phenomenon.
