摘　　要：利用泥岩断层泥比值法(简称SGR法)可估算断层可支持最大烃柱高度。在塔里木盆地英买力地区首次通过改进泥岩断层泥比计算公式,结合油藏和地震资料,计算了英买34井区油藏油柱高度标定参数d和圈闭烃柱高度h,确定了有效圈闭范围,为进行钻前定量评价、降低勘探风险提供依据。Tin, method for estimating highest hydrocarbon cohmm 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 eslimates for the first lime the parameter d. the reservoir till-column height in Yingmai-34 well area, then the hydrocarbon column height h in trap of this well area. making sure the effective trapping ranges, which is helpful for quantitative evaluation hefore drilling and reducing the explnralion risk.
