为了准确刻画砂体的展布特征,满足密井网条件下老油田精细调整挖潜的要求,本文充分利用大庆长垣喇嘛甸油田信息丰富的3D3C地震资料,以喇嘛甸油田北北块二区为例,在建立了处理、解释一体化、大密度合成记录精细标定的基础上,层位上选取地震信息丰富、沉积特征清晰的SⅡ7+8单元为例,提取SⅡ7+8单元与储层信息相关的各种地震属性,通过属性分析、属性优选等方法筛选具有较好信息质量的地震属性切片,形成适合研究区目的层地质情况的最佳地震属性组合,采用线性回归方法、非线性回归方法和协克里金三种方法拟合井点处的属性信息与井参数之间的线性函数关系和非线性函数关系,进行合理的储层参数预测,应用预测结果对研究区储层进行了分析和刻画,提高了储层预测的精度。
In order to accurately characterize the distribution characteristics of sand bodies and meet the requirements of fine adjustment and tapping potential of old oilfields under close well conditions, this paper makes full use of the information-rich 3D3C seismic data in Lamadian Oilfield, Daqing, For example, based on the fine calibration of processing, interpretation integration and large-density synthetic records, taking SⅡ7 + 8 units with rich seismic information and clear sedimentary features as an example, the correlation between reservoir information and SⅡ7 + 8 units , The seismic attribute slices with better information quality are screened by the method of attribute analysis and attribute optimization to form the best seismic attribute combination suitable for the geological conditions of the target layer in the study area. Linear regression method, nonlinear regression method and Xie Keli gold three methods to fit the well point attribution information and well parameters between the linear function and nonlinear function, reasonable reservoir parameters prediction, application of prediction results of the study area reservoir was analyzed and Characterize and improve the accuracy of reservoir prediction.
