迪那2气田为超高压低渗裂缝性凝析气藏,非均质性强。根据该气田岩心、测井、测试等资料,分析单井产能与裂缝及基质物性之间的关系,在此基础上综合单井裂缝段厚度、裂缝密度、裂缝开度和基质KH值,利用Q型聚类法将开发井划分为3类,并将已分好类的气井作为样本利用线性回归建立了分类判别函数,判别结果与聚类法分类结果吻合程度高,为迪那2气田产能分类评价和开发技术政策制定提供了依据。
The Dina 2 gas field is an extra-high pressure and low permeability fractured condensate gas reservoir with strong heterogeneity. According to the core, logging and testing data of this gas field, the relationship between single well productivity and fracture and matrix physical properties was analyzed. Based on the single well fracture thickness, fracture density, fracture opening and matrix KH value, Type clustering method, the development wells are divided into three categories, and the gas wells that have been classified as good samples are used to establish the classification discriminant function by using linear regression. The discriminant results are in good agreement with the clustering classification results, Provide a basis for evaluating and developing technical policies.
