确定报废井层间窜流的同井干扰试井方法

Using Vertical Interference Test to Determine Cross Flow in Abandoned Well

判断报废井层间窜流的同井干扰试井工艺原理在于激动层激动在反应层产生干扰压力（此干扰压力信号的强弱与报废井窜流量等参数有关），以后根据采用压力传播时间、报废井井壁压力计算和压力模拟综合检测来判断报废井层间窜流。通过实例证明，该方法判断报废井层间窜流是可行的，并对多层油藏开发及研究具有重大的意义。

The interference pressure respond is related with cross flow parameters of the abandoned well. It is possible that the cross flow of the abandoned well can be determined by vertical interference test. According to the pressure propagating time,using the wellbore pressure of the abandoned well can simulate the cross flow rate arnong the layers. By analyzing the field examples,it shows that this method to determine the cross flow in abandoned well is feasible and this kind of technology is important for reservoir development.
