应用不稳定试井获取分层注水地层参数

Obtain injection well radius through unstablize testing method

目前常规试井测试工艺技术不能获取分层压力、地层参数和吸水状况资料 ,制约了分层注水工艺的作用发挥。通过利用分层注水管柱 ,我们研究开发适应分注管柱的直接测试仪器和工具 ,应用不稳定试井方法 ,可准确获取层段地层压力、污染系数等地层参数。通过在濮城油田 5口井1 1层次的现场试验研究 ,证明其工艺的可行性 ,为油田注水结构调整提供了可靠依据。

HUANG Hong-qin (1. the Second Production Zhongyuan Petroleum Exploration Bureau 2.Exploration and Development Institute of Zhongyuan Petroleum Exploration Bureau) SUBJECT:Inject techniques can not make full use of its effects because common testing techniques can not obtain pressure radius and inject condition. Based unstablize testing method , We can obtain injection well radius such as pressure etc.Verfied by applicate in 11cells/5 wells in Pucheng Oilfeild ,it has showed the method is usable.
