| 摘 要： | 二连盆地具有低地温、异常低压和单一温压系统的弱流体动力特征;盆地中的油气主要在较高孔渗的输导层、不整合和断裂系统中运移,很少有单一的输导方式形成的油气藏,更多的是其中几种组合成的复杂的立体输导网络即输导系统;在二连盆地中油气运移聚集主要以侧向运移为主,也有垂向运移和阶梯式复合运移,油气分布具有一定的"非势控"特征。 |
| 关 键 词： | 温压系统 输导系统 流体势 油气运移 油气聚集 二连盆地 |

| Abstract: | Erlian Basin is characterized in the weak fluid dynamics of the low ground temperature, abnormal low pressure and singular temperature-pressure system. The oil and gas in the basin migrated mainly in the high permeability conducting layers, unconformity surface and fault system. There is little oil and gas accumulation in the singular conducting pattern, but in the complicated and stereoscopic conducting network, namely the conducting system, composed of a number of assemblages. The oil and gas in Erlian Basin migrated mainly in the lateral direction but sometimes in vertical direction and in the gradient pattern.There fore, oil and gas distrioution is charac-te rized by no-pot ential control. |
| Keywords: | temperature-pressure system conducting system fluid potential oil and gas migration oil and gas accumulation Erlian Basin |
