The Study Of Seismic Methods For Fracture Reservoir Prediction In NanPu Buried Hill

For the multi-phase movement impact and complex structures, strata changes quickly, buried hill carbonate gap-hole reservoirs are heterogeneity, oil and gas accumulation is affected by multiple factors such as structural, strata and reservoir, and thus construct research, strata distribution and reservoir prediction become the study focus of NanPu buried hill reservoir, so the content of the-paper is of carrying out the study of reservoir prediction as the center of crust of weathering and gap-hole reservoirs.Firstly, Carrying out structure interpretation in NanPu buried hill. Analyzing buried hill oil field three-dimensional seismic data; Completing the fine structure interpretation of the buried hill surface and bottom, analyzing general structure characteristics and strata distribution regulation;Secondly, For buried hill surface layer, Using stress field simulation technology and azimuth anisotropy method to find the distribution characteristics fracture; Stress field simulation method can predict structure fracture, and the result shows that structure confect the distribution of fracture, the structure is more strong, the fracture is more development; Based on pre-stack seismic data, Using pre-stack azimuth anisotropy method to predict the density and direction of the fracture, and the result show that fracture distribute in zones, Being compared with FMI, the result is satisfactory.Thirdly, Using the seismic attribute analysis technology to study reservoir characteristics, Through attributes calibrate, Finding sensitive attribute to the reservoir containing oil and gas and comprehensive analyzing favorable reservoir distribution, then using attributions synthesis technology to select favourable part.In summary, Through analysis of geological, reservoir characteristics, petrophysical and geophysical response, Exploring a set of prediction methods for fractured reservoirs, and obtaining a good prediction.
