摘要: 对苏北盆地T油田深层石炭系低渗碳酸盐岩24个水平和垂直岩样进行了储层压力敏感性实验研究,分析了有效压力与孔隙度和渗透率关系,结果表明:1)石炭系储层孔隙压失量与孔隙度之间有比较好的相关性,总体上为:孔隙度高,压失量低;孔隙度低,压失量高。2)渗透率的压失程度与岩样孔渗条件有密切的关系,孔渗性能好,伤害系数小;孔渗透性能差,伤害系数大。

Abstract: The results of pressure sensitivity experiments for 24 horizontal and vertical core samples of low-permeability Carboniferous carbonate reservoir in the depth of T oilfield show that,the relationship of effective pressure and porosity,as following: 1)the pore press-lose ratio of Carboniferous carbonate reservoir correlated with their magnitude of porosity.As a whole,the higher porosity,the lower pore press-lose ratio,vice versa;2)the permeabiltiy press-lose ratio of Carboniferous carbonate reservoir associated with their poro-permeability condition.The well poro-permeability condition,the lesser damage factor,and vice versa.
