Erlian Basin is characterized in the weak fluid dynamics of the low ground temperature, abnormal low pressure and singular temperature-pressure system. 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;
The low pressure is not a true meaning subnormal pressure, because that the piezometric surface is lower than the ground surface, but people give a wrong assumption in the course of showing the relative size of pressure. 在中国西部盆地,因地形起伏较大,承压面低于地表,使得地层压力偏低,但并非真正意义上的低压,只是由于表达方式(起算深度是否等于地表)的原因而造成。
