摘要
油藏综合评价是油藏描述的目的之所在。本文提出的灰色油藏综合评价方法是一种将灰色关联分析与模糊综合评判有机地结合起来进行油藏定量评价的新方法。根据企业标准及油田实际情况,提出油藏综合评价的指标及评价标准,依据专家经验给出各种指标参数对评价结果的权值,通过计算机处理,可以得到三维空间中各样点或网块的评价类别,从而完成三维空间中的油藏综合评价。本方法在实际应用中指导了油田的生产实践,取得了很好的应用效果。
Reservoir evaluation is the aim of reservoirs description. The gray reservoir integrat-ed evaluation technique is a new means that is used to classify reservoirs by combining thegray correlative analysis and fuzzy mathimatics. Many parameters and indices of differentreservoir classifications can be found in the schedule of company standards and they can bemodified to correspond to the actual situation of the oil field. The parameter weights ofvarious indices and parameters for the evaluation rseults also can be obtained by theexpert's experience. By means of computer processing, the evaluation type at any point orgrid block can be obtained in the three-dimensional space. This technique has successfullyguided the practice of oil field development and yielded good results in application.
