地震资料精细解释技术在南堡凹陷的应用

Application of fine seismic data interpretation technique in Nanpu sag.

南堡凹陷储层为三角洲、扇三角洲、河流相沉积,岩性、岩相变化快,断裂发育,准确落实复杂断裂带构造形态及进行地层对比难度大。文中针对储层特点,在区域构造解释、复杂断裂带精细解释、地层精细对比、储层综合预测、岩性圈闭预测等方面逐步形成了一套适应该地区地质特点的技术系列,取得了较好的勘探开发效果。

The reservoirs in Nanpu sag are delta,fan delta and fluvial facies deposit that are characteristics of rapid variation of lithology and lithologic facies,developed fractures,which is difficult to accurately determine the structural configuration of complex fault belt and to correlate the horizons.In view of the characters of reservoirs,the paper expounded how to gradually form a set of technical series suitable for the geologic characters in the region from such aspects as regional structural interpretation,fine interpretation of complex fault belt,fine correlation of horizons,integrative prediction of reservoirs and prediction of lithologic traps.The techniques achieved better geologic results and exploration & development effects.
