Faults Delicate Description Technology by Well-to-seismic Integration is applied to the Sabei Development Area of Daqing oil field

Abstract

Due to the effect of faults, there are some problems such as the high oil wells ratios, and the partial incomplete injection-production relationship which effect the yield of the development in the west of Sabei Development Area that has a high content of oil. The effective method to improve the water-flooding control degree in densely faulted area is to further study the developmental morphology of fault area and improve the injection-production relationship. This passage combines the advantages of interpretation seismic data with high resolution and vertical plane strong data continuity, forming a technology of the description of well seismic combined with fault by breakpoint data logging boot, seismic trace, identify the properties of body, and carry out the verification of the interpretation results of well seismic combined with fault by dynamic analysis methods, implement the fault’s shape in the top surface of each reservoir group of the study area, and applied the guidance of research to guide the adjustment of injection-production system in the West of oil area, improve the injection-production relationship of complex fault zone, achieving a good effect of tapping the potential.
