盘1块断层封闭性研究

The Research of the Sealing Property of the Fault in Pan 1 Block

在明确盘 1块构造特征的基础上 ,着重研究断层封闭性与油气分布的关系。结合工区实例对重点区块应用泥岩含量、泥岩沾污因子、岩性配置关系、声波时差、断层封闭性评价研究等多种方法进行断层封闭性研究 ,对比不同方法的优劣 ,然后应用较适合的方法分析盘1块主要断层不同部位、不同层位的封闭特征。总结其纵向、横向上的变化 ,结合油气的分布特征 ,阐明断层封闭性对油气分布的控制作用。

On the base of the characters of structural in Pan 1 Block,this study emphasises on the relationship between the sealing property of fault and the distribution of oil and gas.According to the working zone,using shale content,shale contaminate factor,lithological association,interval transit time and so on,the sealing property are studied.Then,using the appropriate method,the sealing condition and sealing part of Pan 1 block are analysed.According to the change of vertical and plan and the distribution of oil and gas,the relationship between the esaling property of fault and the distribution of oil and gas are known.
