两种井间示踪剂定量解释方法应用对比研究

Comparative study on the application of two different quantitative interpretation methods

目前常用的半解析示踪剂定量解释方法存在前期准备时间长、解释效率低等问题,难以满足油田要求,需要优选其他方法作为该方法在示踪剂监测过程中的阶段性补充。基于此,以渤海某油田活化水驱井组B1为例,对该井组实施了井间示踪剂监测,并分别利用半解析法及飞行时间法对监测结果进行了定量解释,获取了水窜通道渗透率、波及体积等参数。结果表明,飞行时间法操作简单,解释效率高,结果准确,但适用范围窄,获取参数相对较少。该方法可以作为传统半解析解释方法的补充,进行示踪剂阶段监测结果定量解释,提升解释效率,为油田快速提供井组水窜通道的各项参数,为后续井组开发方案调整及增产措施制定提供参考。

The commonly used semi-analytical tracer quantitative interpretation method requires plenty of time to prepare,which leads to low interpretation efficiency.According to this,IWWT was implemented on B1 well group,Bohai oilfield,which was under activated water flooding,further quantitatively interpreted the monitoring result with semi-analytical method and flight-time method respectively,then the permeability and swept volume of the water channels were obtained.The flight-time method was appeared to operate easily,with higher interpretation efficiency and accurate results,but still had narrower scale of usage and less interpretation parameters.This method can be the supplement of traditional semi-analytical methods to quantitatively interpret tracer monitoring result,which enhanced interpret efficiency and rapid supplies parameters of the water channels of the well group,then helped to adjust the development program and make the proposal of stimulation of the well group.
