We have researched the lower limit of reservoir by the method of Purcell, the sensitivity of permeability, the superposition of relative permeability and capillary pressure curves, distribution of throats at the base of information of capillary pressure.

• 依据毛管压力资料；通过帕塞尔法、渗透率敏感法、相对渗透率曲线与毛管压力曲线叠合法、孔喉分布4种方法对该区储层下限进行研究.
