摘要
在井底产层的条件下,油气水的物性参数随温度和压力的变化而变化。如何可靠地确定油气水物性参数,这一直是生产测井解释中的一个关键问题。在分析现有算法的基础上,本文提出了一种计算油气水物性参数的新途径,即根据具体情况,采用文中的关系式进行多向分析计算,选择最佳结果,从而保证所需参数的可靠性。这一方法既可用于生产测井解释,亦可用于油藏动态分析。
When pay zone is at the bottom of a well,the physical properties of oil,gas and water vary with temperature and pressure. How to correctly determine the physical parameters of oil,gas and water has been a key problem in production logging interpretation. On the basis of the current algorithm,a new method is proposed for calculating the physical parameters of oil,water and gas. That is to make multianalysis with the equations provided in this paper in light of the specific situation, and then select the best result. In this way, the reliability of the parameters needed in the analysis can be ensured. This method can be used for either production logging interpretation or reservoir dynamic analysis.
