vapour volume
2.Gas vapour tests have been conducted in medium viscous oil reservoirs in Block Du 66 of Suguang Oilfield using this equipment. During its testing period of 65 days,the equipment had worked for 1106 hours,the injection pressure reached 7MPa～8MPa,injection temperature was 200℃～250℃,the wellhead pressure 6 MPa,and the total injection volume had been 72×10 4m 3,finally,the clear production results have been got in the test.
