为了定量评价和不断提升三维地质模型的质量,在明确研究区研究目的及地质特征的基础上,通过选取多个关键指标,同时运用层次分析法求取准确权重,并且依据研究区开发阶段及地质资料数量和质量制定合理的标准,利用实际模型与标准进行对比,得出各个指标的实际得分,通过低分项找出模型的不足,最终经过累计得分定量评价三维地质模型的整体质量....

Multilevel Quantitative Evaluation of 3D Geological Model of Complex Fault Block Reservoir

In order to evaluate quantitatively and to raise the quality of 3D geological model, after clarifying the research purposes and geological characteristics of the study area, by selecting several key indicators, and the analytic hierarchy process is used to get the accurate weight. What is more, according to the development stage of the research area and the quality of geological data, reasonable standards are established, the actual score of each index is obtained by comparing actual model with score criterion, and the shortcomings of the model are by the low items. And the overall quality of three-dimensional geological model is evaluated quantitatively by accumlating actual scores of various indicators. Recent studies suggest that the quality of structural model and sedimentary facies model in the study area is good. However, the quality of attribute model is relatively poor, the score of the entire model is 78; the quality of entire model is medium, and there is still more room for this model improvement. The new geological model has been greatly improved compared with original geological model, the score of final model being 94. The quantitative evaluation of 3D geological model has not only the function of quantitative evaluation of model quality but also the advantage of defermining model's shortcoming, which can constantly improve the quality of the model.
