| 摘 要： | 油田水中存在“沉积承压水”和“地表渗入水”两个相对独立而又相互作用的水动力系统，前者由上覆地层重量所引起的地静压力以及地静压力等引起的异常孔隙流体压力所形成，具有内循环承压式水交替特征，后者为大气降水和地表水向储集层的渗入而形成，以外循环渗入或水交替为特征。这两大系统（尤其是前者）的作用在很大程度上控制了含油气盆地中油气的运移、聚集和保存，油气聚集区主要位于水文地质带中的交管阻滞一停滞带内，沉积交替强度的低值区是油气富集区，沉积水的离心流使凹陷中的油气围绕凹陷中心呈带状分布。 |

| Abstract: | There are two different hydrodynamic systems which are independent and of interaction in oilfield waters. They are"depositional artesian water dynamic system"and"surface infiltration water dynamic system",which play an important role in controlling the migration, accumulation and preservation of hydrocarbon in basins,and in controlling the generation and distribution of oil and gas pools. Oil-gas accumulation mainly takes place in retarding and stagnating alternation area of hydrogeologic zone;the low-value area of sedimentation alternation strength is an accumulation area of petroleum;centrifugal flow of sedimentary water causes petroleum in a depression to be distributed in bands around the center of the depression; hydrodynamic anomaly within threshold of oil generation provides equipotential energy space for the formation of oil and gas pools; ancient hydrodynamic balance in local places controls petroleum enrichment;and infiltration of surface water can do good or harm to petroleum preservation. |
| Keywords: | oilfield waters hydrodynamic system hydrocarbon migration and accumulation oil and gas pools |
