Dagang oil recovery three plant operation six area reconstruction seepage field activation oil well productivity
China Petroleum Network Dagang oil three factory work area six fine seepage field reconstruction, through the relationship between injection and production adjustment, injection production adjustment, injection production contradiction of fine management, as of now, the daily oil yield of 80 tons, effectively activated wells.
In recent years, six new sets of variable operation area more than 70 wells, the loss of injection wells 46, the seepage field of the destruction of the original. To this end, technical personnel in accordance with the potential size, and actively explore the old oilfield fill flow control model, has implemented 19 wells, such as water wells repair, corresponding to 39 wells benefit.
In the six District of operation, the 4 fault blocks enter the double high development stage, and the contradiction between injection production and production is difficult to control. Technical personnel put forward the suggestion of changing the direction of liquid flow by intermittent periodic water injection, thus enhancing the efficiency of water injection. In the first half of the year, the production of 15 wells benefited from 53 tons to 95 tons by fine water injection regulation in the 7 wells.
In addition, the six work area to carry out "day, week, month summary of comparative analysis", continuously deepening fine injection production management, strict measures of argumentation, process control and effect analysis, standard potential of oil and water wells, to achieve closed-loop management.
