High Efficient Development Strategies and Key Technologies for Turbidite Sandstone Reservoirs in Deep-water
摘要
Abstract
In response to the challenges of high investment in deepwater turbidite sandstone oilfield development,limited available data for project planning,high requirements for the success rate of the one-time well network,and striving for max-imum oil recovery through high-speed oil production,researches have been conducted on reservoir characteristics of turbidite sandstone,geophysical prediction,geomodeling and numerical simulation integration,and efficient development strategies.It has been revealed that deep-water turbidite sandstone channels can be subdivided into composite channels,single channels,branch channels,and submarine fans as microfacies.Key geophysical technologies have been developed including seismic point identification of turbidite channel reservoirs'original oil-gas interface;amplitude attribute characterization of the exten-sion distribution and oscillation range of turbidite channels,division of multi-stage channel cutting relationships on seismic profiles,prediction of sandstone thickness through wave impedance inversion,characterization of changes in water drive front using 4D seismic monitoring techniques.Technologies of development indicators and production parameters optimization for reservoir-well-pipeline-network-FPSO integration have been established.Development strategies for turbidite channel sand-stone reservoirs such as irregular well networks deployment,economic limit of single well controlled recoverable reserves,early water injection at the edge with a large well space have been summarized.The above key technologies and models have been applied to the development of P Oilfield in Block 18 of Angola,achieving the goals of fewer wells and high production,high investment and high return,making possible the efficient development of the deep-water marginal reserves that have not been utilized for more than 10 years,and providing reference for the development of similar reservoirs.关键词
