Research Of Integration Of Wells And Seismic In Fine Reservoir Description

In recent year, high-precision Seismic data acquisition technique, prestack imaging,reservoir prediction technique of geophysical exploration technology developed rapidly. Asa result the precision and efficiency of exploration and development of oil and gas also havebeen improved greatly. Geophysical exploration technology has been a dominant technologyand the importance of high density3D seismic data has been realized gradually in the oilfielddevelopment. But well pattern density of external oilfield is low, research of reservoir usingintegration of seismic and logging is restricted. Research of integration of seismic and loggingin fine reservoir description and its applications has not been taken.In this article through seismic interpretation of high density3D seismic data of the NorthⅡWest Tract with8.16km2, the fault distribution and development of Micro-relief structuresof SII oil layers are studied by integrating well log and seismic information in dense wellpattern.19faults and19Micro-relief structures are identified. The distribution characteristicsof reservoir of SII oil layers are researched and thin sand bodies with thickness about2metersto4meters are identified, through optimizing reservoir inversion model. Proper technique ofsedimentary micro-facies, reservoir and structure prediction using integration of well andseismic is formed. Realization of reservoir is improved and the application of seismic data ismore extensive. According to the study,68new wells are disposed and stimulation treatmentsof22oil and water wells are taken to improve the production of oil wells in the North ⅡWestTract. Effect of stimulation treatment is well.
