Abstract: The method for estimating highest hydrocarbon column supported by the fault with shale gouge ratio (SGR) has not been used in Yingmaili area, Tarim basin. By improving the formula of SGR, combining with the reservoir and seismic data, this paper estimates for the first time the parameterd, the reservoir oil?column height in Yingmai?34well area, then the hydrocarbon column heighthin trap of this well area, making sure the effective trapping ranges, which is helpful for quantitative evaluation before drilling and reducing the exploration risk.
