中文摘要：

针对胜利油田罗家地区以构造裂缝为主、与断层关系密切的特点，本文采用地震资料相干分析和方差分析技术，力求精细而准确地确定该区目的层的断裂系统；提出了地震吸收系数分析技术，期望为确定目的层段的裂缝发育分布提供重要的证据；利用全方位地震信息进行AVA、VVA方法的研究，可望定量地得到目的层段的裂缝方位和密度分布情况；针对AVA和VVA技术的不足，采用了不同方位角阻抗的变化来检测裂缝发育情况的IPVA方法．实例分析表明，该套泥岩裂缝储层勘探方法取得了良好的效果，在泥岩裂缝油气藏定量检测方面获得了重要进展．

英文摘要：

In Luojia area of Shengli Oilfield tectonic fissures are developed mainly in shale fracture reservoirs and they are closely related with faults. In combination with the specific geologic characteristics of the work area, the coherence analysis technique is adopted firstly in this paper to strive for accurately establish the fault system. Secondly, the absorption coefficients analysis is applied to the work area for detecting the distribution of the shale fracture. By using full-azimuth P wave amplitude （AVA, Amplitude variation with azimuth） velocity （VVA, Velocity variation with azimuth） could be expected to evaluate the principal axis of the fracture and the crack density. At last, due to the disadvantages of the AVA and VVA methods, this paper presents the impedence variance with azimuth （IPVA） method to detecting the shale fracture. Application results show that we successfully predict shale fracture reservoirs, which lays sound foundations for comprehensive description of shale fracture in the area.
