    摘要: 本文提出一种用于油气田地质油藏特征及开发指标定量化类比的扇面关联度分析法。该方法首先进行目标油气田地质油藏特征分析和主控因素确定。在此基础上,统计目标油气田和类比油气田的主控参数,建立扇面坐标系,设立主控参数置信度序列,并对扇面坐标系进行调整。然后,在扇面坐标系中绘制目标油气田和各类比油气田的扇面图,并筛选出相似油气田。之后,采用考虑置信度约束条件下的扇面关联度分析法进行目标油气田与多个相似油气田的关联度计算,通过关联度大小对油气田相似程度进行定量化排序,从而最终确定高度相似的油气田。该方法可以从图形和解析两方面定量化精确定位与目标油气田相似度最高的类比油气田,并据此用类比油气田开发策略和实际的开发效果对目标油气田的开发方案制定提供依据,具有较好的实际应用价值。In this paper, a new type of sector correlation analysis method that can be applied in quantitative analogy of characteristics and development index of gas oil fields is proposed. Firstly, the engineers should analyze the reservoir characteristics and ascertain the dominant control factors, and on this basis, collect the dominant control data of the target gas oil field and analogous gas oil fields, establish the sectoral coordinate, set the dominant control data confidence level sequence and adjust the coordinates correspondingly, then, draw the sectors of the target gas oil field and the analogous fields in the sectoral coordinate and screen out the similar fields. Based on these sector data, the correlation between the fields can be calculated by use of the sector correlation analysis method considering the confidence level sequence. After sorting the value of sector correlation, the similarity degree between the fields and the most similar field can be determined finally. The new type of sector correlation analysis method can be applied in quantitative position of the best analogous gas oil field graphically and analytically, which provides the referential basis to determine the development plan of target field from the development strategies and effect of the analogous fields and has good practical application value.
