为了进一步提高碎屑岩油层沉积微相图的制图精度，并增强其横向预测性，以满足油气藏开发的需要，在大庆长垣葡北油田二断块，针对葡萄花油层中声波曲线不能有效区分储层与围岩，探索出了一套单井相与拟波阻抗地震反演数据结合沉积微相制图方法。该方法通过各种测井曲线储层敏感性交汇分析，找出储层敏感性测井曲线为自然电位曲线，并将其转换为阻抗值量纲的曲线，提取出高频部分，与原始波阻抗曲线低频部分合并，形成能反映储层变化的拟波阻抗曲线。然后，将重构拟波阻抗曲线用于地震反演。依据地震反演预测结果，分沉积单元精细调整拟波阻抗砂泥岩的门槛值，使阻抗体所反映的砂体厚度与测井解释砂体厚度纵向上具有最优的符合率，绘制各沉积单元砂岩厚度的平面分布。在绘制沉积微相图时，井点根据其单元所属的相带类型进行外推，井间微相由砂体厚度和形态确定，利用反演信息确定河道宽度，反演的波阻抗切片确定各沉积微相发育形态。最后，进行单井沉积相校正，完成各沉积单元沉积微相图。该方法强调单井相与地震拟波阻抗反演数据的结合预测沉积微相分布特征，实际应用效果表明新的制图方法精度高、实用性强，能有效推动油气藏精细开发调整。

In order to meet the need of further reservoir development it is essential to improve the cartographic accuracy of the microfacies map for clastic rock reservoirs, especially to enhance its prediction capability in the cross well area. In the second fault block of the Pubei oil field in Daqing placanticline, the reservoirs and the surrounding rocks of the Putaohua Formation can not be differentiated only according to the acoustic attributes; therefore, a cartographic method which combines the single well facies with the quasi-impedance results is proposed. Firstly, from all the logging attributes, the optimum logging attribute which can differentiate the reservoirs and the surrounding rocks is chosen. A spontaneous potential attribute is chosen in the Putaohua Formation. Secondly, the seismic inversion is processed by using the quasi-impedance logging curve and adding the information of the spontaneous potential curve. Thirdly, the cross well microfacied types can be predicted by the inverted sand thickness; the channel width in the map can be calculated based on the inversion information; and the whole pattern of the microfacies map can be determined on the basis of the quasi-impedance inversion slices. Finally, the microfacies map is completed after the calibration of the single well facies. The real application shows the high accuracy and the practicability of the new mapping method, for the reservoir development and adjustment.
