| 摘 要： | 通过室内实验、理论计算确定流体非达西渗流的启动压力梯度,确定建立了有效驱替压力系统下的合理井距。研究表明,影响低渗储层驱替压力系统建立的最主要因素是启动压力梯度。在GGY油田低渗透油藏的开发中应适当缩小注采井距提高驱替压力梯度,采取整体压裂措施减小启动压力梯度。

| Abstract: | The effective driving pressure system and injector producer distance were determined by using the start-up pressures gained from laboratory experiment and site measurement. Many influencing factors of building up driving pressure system in low permeability oil reservoirs were analyzed .The results indicate that the chief influencing factors are start-up pressure gradient. In the development of the GGY low permeability oil reserviors, shortening injector producer distance may raise displacement pressure gradient and adopting integral fracturing may reduce the start-up pressure gradient. |
