摘要
有效储层是指现有工艺条件下能获得工业油流的储层。有效储层的物性下限包括孔隙度、渗透率和含油饱和度三个参数。本论文详细讨论了有效储层物性下限的确定方法,主要包括测试法、经验统计法、含油产状法、束缚水饱和度法、含油量累积法和最好孔喉半径法等。不同方法所依据的原理和资料不同,得出的结论会有所差异。在实际应用中,可以根据相关测试数据选取适当的方法,从不同侧面对有效储层物性下限进行综合分析和评定。
The effective reservoirs are the reservoirs with industrial oil production capacity under existing technology conditions.The physical property cut-off of effective reservoirs mainly refers to the cut-off of three parameters of porosity,permeability and oil saturation.In this paper,methods on determing the physical property cut-off of effective reservoirs have discussed in detail.They are the testing method,the empirical statistical method and the oil occurrence method etc.Due to the principles and information which those methods based on are different,the conclusions would be various.In practice,it's better to select several suitable methods according to existing test data,and give the physical property cut-off of effective reservoirs a comprehensive assessment.
