【摘要】 在碳酸盐岩储层中同样发育着非渗透性隔层 ,它们主要由泥质含量较高的致密层和构造裂缝不发育的纯岩性致密层组成 ,可以从岩性特征、电性特征和构造裂缝发育特征等方面进行识别与划分。任丘雾迷山组中的非渗透性隔层以泥质致密层为主 ,纯岩性致密层相对较少 ,且分布很不稳定 ,采用综合评价方法可将其分成四类。其中 ,第一类非渗透性隔层对油藏中油水分布规律起着最重要的控制作用更多还原

【Abstract】 The impermeable barrier layers exist in carbonate rock formation profile and consist of shaly compacted zone and lithological compated zone. The former is the formation with high shale content, and the later is the formation of tectonic fracture development weakly. Depending on the lithological characteristics, electrical characteristics and tectonic fracture development, they can be distinguished from formation profile. The impermeable barrier layers in Wumishan member of Renqiu oilfield are mainly composed of shaly carbonate in compact zone. By using the comprehensive evaluation coefficient method, the impermeable barrier layers are divided into four types. It is shown that the type 1 has an important effect on controlling the distribution of oil water in reservoir.更多还原
