Study On Well Seismic Descriptive Techniques Of Submarine Distributary Channel Sand Body In The Western Area Of Bei 3 Area

At present,the underwater distributary channel sand bodies that are simply based on well data are only about 60% predicting the coincidence rate of microfacies,and it is difficult to predict the narrow channel sands,predict the continuity,combine the modes,and the distribution direction and bending degree.The existing description precision is far from meeting the needs of the development and adjustment of the oilfield with ultra-high water cut times and the need for fine tapping potential.In this paper,the sedimentary environment and sedimentary microfacies of the time unit,seismic response characteristics of underwater distributary channel sand bodies,extraction and optimization of seismic attributes,seismic reservoir inversion methods and parameters,subsurface flow diversion,and sedimentary microfacies prediction of river tunnels Research on the description method of well-seismic combination of technology and different types of underwater distributary channel sand bodies summarizes the spatial distribution rules of underwater distributary channels.Therefore,the method for describing well seismic combination of distributary channel sand bodies was developed to improve the accuracy of reservoir prediction and improve the development effect of oil fields.
