盐构造的识别、分类及与油气的关系

Recognition and classification of salt structure and relative to oil/gas

盐构造是近年来勘探的热点。本文详细介绍了运用重力特征、地震反射特征、现场录井及测井识别等识别盐构造的方法;分析了盐构造的沉积特点及成因;根据盐体的埋深、外部形态、盐构造成因及其与围岩的接触关系进行了分类。在此基础上,进一步论述了盐构造的形成机制、盐构造与油气的关系。由于盐构造的空间几何特征的复杂性,在勘探方法的选择上,应将三维地震观测作为基本的数据采集方式,将三维叠前深度偏移作为最终有效的处理手段。

The salt structure is hot spot of exploration in recent years.The paper introduced in detail the recognition methods using feature of gravity,seismic reflections and logging in site to recognize salt structure;analyzed sedimentary feature and genesis of salt structure;and made classification according to buried depth of salt body,configuration,genesis of salt structure and contact relationship with mother rock.On that basis,the paper further expounded forming mechanism of salt structure and relationship wit...
