Architecture Analysis And Geological Modeling On The Reservoir In Estuary

As the representative of domestic and foreign geologists,Maill and Wu Shenghe have done lots of work to study.architecture mode of fluvial facies and scored great successes,but lack of research on Architecture mode in estuary.On the basis of literature research about tidal controlled estuary,the paper use core data,litho-facies,physical data and logging data to study distribution and thickness law of sand bar by using deterministic modeling and multi-point statistic.Establishment of architecture relationship will provide technical guidance for SAGD development.The main research contents and results are as follows:(1)Analyze and sort litho-facies data of single well and establish lithofacies associations mode.We mainly use core,litho-faces data to identify lithofacies associations mode in the area.Different mode reflect differences in sedimentary environment.We use well data in different parts of tidal sand bar to analyze sedimentary characteristics of single tidal sand bar.(2)Based on the study of single well architecture mode,connected wells ' profiles are used to contrast and analyze the architecture in cross-well.By analyzing vertical and horizontal characteristics,we draw 2D architecture mode.Deposition trend and development characteristics in the vertical layering are summarized overall.(3)Study the classification and characteristics of 3d spatial data model.Core data,interpretation data and well-top data are used to establish the 3D geological structure and architecture mode.
