南川区块断层精细解释研究

Study on the fine fault interpretation in Nanchuan district

为进一步落实南川区块断层展布特征,针对南川构造特征,采用"三层楼"构造模式进行该区块的构造精细解释,结合分频融合技术、倾角相干技术、曲率技术、构造熵技术、AFE技术、倾角曲率等技术预测断层分布范围和展布方向,应用多属性体进行断层解释,实施三维空间断层断面解释质量控制,提高了断层解释的精度。在全区解释闭合了大小断层96条,为油气的勘探开发提供了理论依据。

In order to further determine the distribution characteristics of the faults in Nanchuan district,we adopted the"three stories"structure for the fine structure interpretation,and combined with the technology such as the frequency division fusion,inclination of coherent,curvature,structure entropy,AFE and dip angle of curvature to predict the distribution of the fault.The application of the multiple attributes for the fault interpretation and the quality control of the fault section interpretation in 3D space improved the accuracy of the fault interpretation.There were 96 faults interpreted and closed in the district.It provides theoretical basis for oil and gas exploration and development.
