ADVANCE OF WELL TEST ANALYSIS FOR HETEROGENOUS RESERVOIRS
-
摘要: 在明确了试井分析所用的油藏分类标准的基础上, 从油藏多孔介质的非均质性、油藏流体的非均质性、以及数学模型的解法和试井解释方法4个方面, 对非均质油藏的研究成果进行了概述, 归纳出了规则的非均质油藏和随机的非均质油藏的概念, 并分析了非均质油藏试井理论研究的发展趋势, 指出结合油田地质资料和油藏开发动态资料进行综合试井资料分析是试井理论发展的必然趋势, 数值试井方法是试井未来发展的方向.Abstract: Based on the definition of the reservoir types used in the welltest analysis, this review forcuses onfour points: theformation heterogeneity, the fluid distribution, the mathematical model andthe test data interpretation method. The concepts, such as the partiallyregular heterogeneous reservoir and arbitrarily heterogeneous reservoir, areexpatiated in this paper. The present state and future trend of research arepointed out. It is best to combine the geological data and the dynamicdata of the reservoir development to interpret the well test data. Numericalwell test analysis method is the new trend for the future test analysis.
