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。
The results of pressure sensitivity experiments for 24 horizontal and vertical core samples of lowpermeability 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 presslose 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.
