摘要： 油田开发后期,油、水井间连通关系随开发条件改变而呈现“动态”变化规律。采用多元线性回归思想,提出了一种基于油、水井生产动态的油藏连通性反演方法。在准噶尔盆地陆9 井区J2x4油藏的应用结果表明,井间连通关系可划分为各向均匀连通型、单向连通型、线状连通型和单井突进型等4 种类型。其中,单向连通型和单井突进型注水井组所占比例较大,反映了油藏非均质性特点;对于边底水活跃油藏,注、采井间连通性越好,地层能量越可以得到有效补充,越可有效抑制边底水入侵。

Abstract: In the late stage of an oil field development, the oil-water interwell connectivity presents dynamic variations with the change of development conditions. This paper proposes the oil-water well production performance-based inversion method for reservoir connectivity using multivariate linear regression. Field application in J2x4 reservoir of Wellblock Lu-9 in Junggar basin indicates that the interwell connectivity can be divided into 4 types: uniform connectivity, unidirectional connectivity, linear connectivity and single well onrush connectivity, of which the unidirectional and onrush connectivity-type waterflooding well groups are dominant, showing it is characterized by heterogeneity. For the reservoir with active edge and bottom water, the producing energy can be recovered effectively while its interwell connectivity is good.

Key words: Junggar basin, connectivity, production performance, multivariate regression, mathematical model
