| 摘 要： | 针对莫116断块三工河组砂体展布复杂、储层非均质性强的特点，在构造解释、测井资料处理与解释以及沉积微相研究的基础上，建立了莫116断块的三维地质模型。由于传统模型无法准确描述其地质状况的复杂性，所以在建立属性模型时，采用改进后的加权线性规划法对变差函数进行拟合，随后对地质储量进行复算。研究表明，改进后的加权线性规划法能够显著提高变差函数拟合精度，建立的属性模型更为合理，以此为基础计算所得的储量值也更为精确，研究成果对类似地区的地质建模研究具有借鉴意义。

| Abstract: | The reservoirs of Sangonghe Formation in Mo116 Fault Block of Mobei Oilfield has some typical characteristics that the sand-body distribution is very complicated and the reservoirs have strong heterogeneity.To better characterize the discontinuity of the reservoir physical properties，the structural model，sedimentary microfacies model and attribute model are established based on structure interpretation，logging data processing and interpretation and sedimentary study.In the process of establishing the attribute model，an improved weighted linear programming method is applied to fit the variogram，then the recalculation of the geological reserves is also completed on the basis of the models.Research shows that the fit accuracy of the variogram is increased significantly by using the improved weighted linear programming method，the attribute model is more reasonable and the reserves calculation based on the geological model is more accurate，which lays the foundation for further development and adjustment of Mo116 Fault Block.In general，it has certain reference significance for the application of geological modeling in similar area. |
