在对油藏进行注水开发过程中,明确注入水推进方向和水驱前缘位置是十分重要的。以摩尔一库伦理论、断裂力学准则等理论为基础的微地震水驱前缘监测技术可以对注水井进行监测,能够得到该井的水驱前缘展布状况、注入水波及范围及水驱主流方向,从而可以直观的检验注水开发效果,为后期注采井网的调整提供依据。该技术在柳102断块LN 1-5井组的现场应用监测解释结果与井组动静态资料分析结果一致,说明微地震水驱前缘监测技术可以有效的监测和评价注水开发效果。

It is very important of determining the impulse direction of injected water and the location of water flooding front during waterloo development.Micro-seismic monitoring technology that based on the Molar of a Coulomb theory and the theory of fracture mechanics criteria can detect the distribution of water flooding conditions、swept area and the main direction of injected water,which can directly inspect the effectiveness of water injection,and provide the basis for the adjustment of injection-production pattern.The results explained by the technology were consistent with ones that analysed by static and dynamic data in the Liu102 block,Group LN1-5 well,it shows that the technology can effectively monitor and evaluate the effect of water flooding.
