Application Of Dynamic Monitoring Data In Offshore Oilfield

Reservoir dynamic monitoring measures is using lots of underground representative data and in oil layer which can reflect the characteristics of the dynamic change by kinds of instruments and different test methods.On this basis through pulling together all these data, the system analysis all kinds of test data to guide oil deposit’s rational exploitation for improving recovery efficiency. Reservoir dynamic monitoring usually includes: pressure monitoring, water injection profile monitoring, remaining oil distribution monitoring, water injection well tracer material monitoring and water quality tracer monitoring.It is estimated that water drive reserves of Hainan 3 fault block will increase 12×104t and its injector-producer connection factor will increase from 82.1% to 84.3% by strengthening the research and use of dynamic testing data, guiding Hainan 3 fault block’s capacity deployment and excavating potential measure, guiding comprehensive treatment of water drive reserves. The percentage of injection and production wells enhance from 1:2.13 to 1:2.0, the control degree of water drive reserves enhance from 78.1% to 81.3% in addition producing degree also enhance from 76.4% to 79.2%. The total input of this measure is about 539.5 million yuan, enhanced production of oil add up to 8551 tons, and it creates economic benefits 14.44 million yuan according to 5000yuan/t crude oil price eliminating cost of 2680yuan/t in Hainan work zone. All of this has theory and real meaning.
