摘　　要：M凹陷为低孔隙度、低渗透率型储层 ,孔隙结构复杂 ,常规测井资料反映储集层渗透性很差 ,用流体声阻抗和纵波弹性模量可有效对储层流体性质进行计算 ,异常压力在二连地区广泛分布。对该凹陷异常压力趋势线进行模拟 ,找出异常压力高、低值点 ,根据 16口井的资料分析异常压力分布规律 ,对今后的产能及布井方案提出了建设性意见。Depression M is characterized by low porosity and low permeability .It is very difficult to interpret this complex pore structure reservoir using conventional log data. Fluid property can be effectively calculated by fluid sonic impedance and elastic modulus of P-wave. Anomaly pressure spreads widely in Erlian basin. Simulated is the anomaly pressure line to find out high and low pressure points.16 samples are used here to analyse anomaly pressure’s spreading law. Constructive suggestions are proposed for productivity forecast and later drilling scheme.
