摘　　要：新疆MXZ油田为复杂砂砾岩储层,油藏评价和储量计算的关键参数有效厚度用常规方法较难确定。利用自然伽马相对值和声波时差有效地判断出渗透层,结合电性特征,从渗透层中识别出油水层,综合应用测井、取心、试油及分析化验等多种资料,建立了复杂砂砾岩储层的有效厚度划分标准。据此标准,划分了MXZ油田共11口单井的有效厚度。MXZ oilfield is a complex glutenite reservoir in Xinjiang oilfield, its net or effective thickness, a critical parameter relative to reservoir evaluation and calculation of reserves, is difficult to determine by conventional method. First, we judge permeability reservoir by analyzing natural gamma values and sonic interval transit time values; Second, recognize oil-bearing zone from permeability reservoir combining with electrical characteristics; Last, set up net thickness standards of this complex glutenite reservoir by using logging, coring, production testing and laboratory testing data, etc. We have put the standards into use in logging interpretation and evaluation. According to the standards, the effective thicknesses of single well of 11 wells in MXZ oilfield have been determined.
