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。
This paper presents a method to study the properties of oil (water) wells and oil wells using daily production test data, which can be used to determine the distribution of closed faults and the pressure transmission capacity between wells. It can be used for stable well testing and hydrology Explore deeper roles without the need for specialized testing. Based on the mathematical foundation of cybernetics, this paper analyzes some theoretical issues related to the object of study. The properties of the pressure transfer function and the approximate general solution structure of seepage motion of compressible liquid in multi-well system in heterogeneous formation Important results, so as to get a practical method to study the nature of oil reservoirs, and verified with examples. Especially for the study of multi-fault reservoirs more simple and practical, the proposed research methods have a wide range of applications.
