二连盆地洪浩尔舒特凹陷安山岩储层预测方法
|
摘要
二连盆地洪浩尔舒特凹陷火成岩油气藏是一个重要的勘探领域,分布广泛的阿三段安山岩为主要目的层,有效预测火成岩储层分布情况是勘探难点之一。针对安山岩储层特征及预测难点,利用自然伽马拟声波反演、自然伽马储层参数反演、地震属性等手段预测了安山岩空间分布及厚度变化。根据安山岩岩相特征,综合断裂结构、地震相、能量、频率衰减属性、安山岩反演预测结果及钻井厚度等资料,进行了安山岩岩相预测。分析认为,裂缝发育带、中距离火山斜坡相为有利的储集相带。
The pyrolith reservoir of Honghaoershute sag in Erlian Basin is an important exploration area, where the andesite widely distributed in the third member of Aershan Formation is the main target strata, and it is one of the exploration difficulties to predict the distribution of the pyrolith reservoir effectively. Aiming at the andesite reservoir characteristics and prediction difficulties, the authors predict the spatial distribution patterns and the thickness change of andesite with some measures such as natural gamma analog acoustic wave inversion, natural gamma reservoir parameter inversion, seismic attributes and so on. According to the characteristics of andesite lithofacies, synthesizing the fracture structure, seismic facies, seismic energy, frequency attenuation attributes, the result of andesite inversion prediction and the strata thickness gotten from drilling, the authors predict the andesite facies. It is believed that the development areas of the fracture and the volcano slopes at a middle distance from the volcano center are favorable reservoirs.
