摘要: 低渗透油藏岩性发育不均匀,常表现为多重复合油藏特征。这一特点难以从油井测试资料中观察到,而在水井测试资料却有所反映。水井测试资料曲线往往存在后期多次上翘现象,而显示出油水井间的地层特点。但是,对这些资料的解释具有一定难度。在前人研究的基础上,建立了多重复合油藏试井理论模型,研制出理论图版,分析了压力动态特征。文中列举出油水井对应测试的分析实例,以此说明加强低渗透油藏注水井压力动态分析的必要性。

Abstract: Low-permeability reservoir often shows characteristics of multiple composite reservoirs because of the heterogeneity of lithologic development.These characteristics are difficult to be observed from oil well test data,but they could be reflected with the water well test data.The later curves of water injection well test data often upward.It is difficult to interpret these data. So,the study of well test analysis theory about heterogeneous reservoir is very important for low-permeability reservoir in complex geology.Thus,the theoretical models of multiple composite reservoir are presented and the corresponding typic curves are ploted,and the pressure transient characteristics are analyzed in this paper.Some analysis examples of oil and water well test are given to show the necessary for analyzing water injection well test data.

Key words: multiply composite reservoir, low-permeability reservoir, water injection well, well test analysis, pressure
