| 摘 要： | 川西坳陷新场气田须家河二段为低孔低渗、超深超压、致密岩屑砂岩储层,裂缝对储层有着至关重要的作用。通过岩心裂缝识别并结合成像测井裂缝识别归纳总结研究区储层的裂缝特征,在此基础上选取裂缝和非裂缝以及有效裂缝和非裂缝样本,提取常规测井参数,运用逐步判别法、样品检验概率判别法、裂缝有效宽度和孔隙度计算法对储层裂缝进行了研究。认为无充填和半充填的垂直缝及高角度缝为有效裂缝,与研究区实际情况相符。 |

| Abstract: | The second member of Xujiahe Formation is a low - porosity and low - permeability, extra - buried depth and over pressure, and tight greywacke reservoir. Fracture plays a crucial role in reservoir. By identifying core fractures, and combined with imaging logging fracture identification, the characteristics of reservoir fractures were generalized and summa- rized. On the above basis, reservoir fractures were studied by choosing samples with fracture and non - fracture, effective fracture and non - fracture, extracting conventional wireline logging parameters, using Bayes＇ stepwise discrimination, the probability discriminant method for sample survey, and the calculation method for fracture effective width and porosity. It is considered that vertical and high - angle fractures which are opened and semi - filled are effective fractures, and this is consistent with the fact of the research area. |
