Abstract: | Gas lift water location technique is to simulate the production status of oil producing well with gas lift fluid displacement method. Combined with production logging it determines production profile giving the oil and water production rate of each specific zone. Gas lift process design, logging suites needed, operational procedures and the log interpretation method are presented in this paper. Its application results in Dagang Oilfield show that it has many features such as simple test procedures, complete parameters obtained, high interpretation accuracy and better economic efficiency. It provides the basis for maintaining the oil production rate and controlling water producing in high water cut oilfield. |
