摘要
通过对不稳定试井测试所得到的压力特征曲线(双对数曲线)进行分析、研究,充分利用试井特征曲线,研究其反映出的油藏地质特征,进而分析油藏特性的变化,并将分析研究结果应用于生产中,这极大地拓展了注水井试井资料的应用领域。提出了一种有效提高不稳定试井资料在油田开发中的利用率的思路,即认为试井资料所得的地层参数的精确性固然重要,但更重要的是要抓住其特征曲线反映出的关于油藏特性方面的信息,以更好地认识油藏,指导油田开发。这对于油田开发管理有一定的现实意义。
The transient well test data, especially of injectors was seldom used, except in calculating formation pressure. However, since the development of Tuha oilfield, large amounts of transient well test data acquired hawe been widely used in the development of the oil field. The reservoir geologic characteristics reflected in transient well test curve was obtained through analysis and research, hence the application field of injector well test data was extended. This is helpful for development management.
