摘　　要：无源地震勘探（Passive Seismic）理论认为，油气藏自身的一些活动可以产生微地震，根据波速场分布与地下渗流场分布具有相关性的特点及摩尔-库伦和断裂力学理论，对孔隙流体压力变化和微裂缝的再次张开与扩展时产生的一系列微震波进行监测，得到地下波速场特征，以此为基础求得特低渗的吴410井区长6油藏水驱前缘、注入水波及范围、非均质性等资料，取得了较好的应用效果。Passive seismic theory thinks that some autologous activities can creat microseism in oil-gas pool. According to wave velocity field and infiltration field＇s correlation characteristic, mole-kuln theory and mechanics theory in fracture, we can monitor pressure changes in pore fluid and micro-seismic wave though micro-flaw opening and expansion once again. We can obtain character of wave velocity field. In the end we can gain some data such as the advancing edge water diver, conformance dimension of injected water and heterogeneous in hyposmosis Chang6 Wu410.
