文摘

Combined the advantage of reservoir simulation and conventional reservoir engineering methods, the paper proposes a quick method for production performance prediction, which is based on type curves generated from reservoir simulations of sector model. Fine reservoir simulation is conducted based on the fine geological sector model of the large sandstone reservoir, and type curves of different reservoir type under different development options are generated. Then based on results of reservoir type classification for all layers, well productivity and injectivity evaluation, production profile of the whole field can be predicted. This new method can reflect the impact of reservoir heterogeneity and development option change on reservoir performance. Take a large multi-layered sandstone reservoir Upper Shale reservoir in Rumaila Oilfield for example to illustrate the workflow. The comparison between results of fine reservoir simulation and that of the new method validate reliability of the new method, and the new method consume much shorter time.
