Abstract: A method of studying reservoir properties in and between oil wells based on daily production testing data is proposed for determining the distribution of sealed up faults and the pressure transmissibility between wells. It gives better result than the stable well testing and hydrogeological exploration, without resorting to any special testing. Some theoretical problems related to the object of study are examined on the mathematical fundamentals of the theory of control, and significant results are derived in respect to the nature of pressure transmission functions and the structure of approximate general solution for flow of compressible fluid in a multiple well system in the heterogeneous formations. The method has been proved to be simple and practical particularly in the study of multi-fault block oil pools.

摘要： 文中提出了一种利用日常生产测试资料研究油(水)井及井间油层性质的方法,可用于确定封闭断层的分布、井间压力传导能力等重要性质,可起到比稳定试井和水文勘探更深刻的作用,而无需专门的测试。文中应用控制论的数学基础具体分析了与研究对象有关的一些理论问题,对压力传递函数的性质,对非均质地层中可压缩液体在多井系统中渗流运动的近似通解式结构均引出了重要结果,从而得到了研究油层性质的实用方法,并用实例做了验证,特别对于研究多断块油藏更为简便实用,文中所提出的研究方法有广泛的应用前景。
