合注井分层测试工艺技术

General Injection Well Layered Testing

针对中原油田合注(笼统)注水井管柱的特点,开发了一项适应合注井分层测试的工艺方法,实现了压力、流量分层测试,得到了各层段的吸水能力、分层注入参数、启动压力、指示曲线,并获得了分层段的渗透率、表皮系数等参数,为进一步选择合理的采油工程措施,多层配注方案提供依据。

According to the features of general injection well tube in Zhongyuan oilfield,we have developed the method of adapting to general injection well layered testing.This achieved that injection wells pressure system layered test.It can test each layers absorb capacity,layered injection parameter,start pressure,indication curve,and it can also abstain layered sections permeability,skin and so on.This test can offer basis for choice reasonable oil production measure and layered distribute injection plan.
