银额盆地典型凹陷构造解释及含气性分析

Structural Interpretation and Gas-bearing Property Analysis of Typical Depression in Yin'e Basin

银额盆地石炭～二叠系巨厚,油气地质条件良好,具有良好的油气勘探前景,但受地质及自然条件影响,勘探程度较低,地震以普查为主。通过层位精细标定、精细构造解释和AVO储层预测方法,对银额盆地2个典型凹陷石炭～二叠系含气性进行评价,初步预测了天草凹陷石炭～二叠系有利含油气区带及有利储层发育带,对该区油气勘探具有重要指导。

The Carboniferous-Permian in Yin'e Basin is of greate thiekness,it has a fine petroleum geological condition and good exploration potential.But affected by geological and natural conditions,the exploration degree is low,the seismic exploration is mainly by general survey.In the process of fine calibration for horizon,fine structural interpretation, AVO reservoir prediction methods,gas bearing capacity of Carboniferous-Permian of typical depressions in this region is evaluated,primarily predicting the beneficial reservoir growth zones and gas accumulation zone in Tiancao Depression.It provides an important guidance for exploration activity in this area.
