摘要: 根据Vail等人的地震地层学观点,利用地震波的振幅、连续性、相位和波形等变化特征,
在常规精细处理的地震叠偏剖面上对川中大安寨储层划分出两种微地震相。再通过钻井、地
质、地震三方面综合分析、研究,最终提供了该区的含油(气)相模式,即波形较连续、强能量的单波微地震相,原则上不产油(气),而连续性较差、低能量的复波微地震相为产油(气)的最佳模
式,从而加深了对川中大安寨储层的再认识。

Abstract: From the view of Vail et. Al for the seismic stratigraphy, two microseismic phases can be classified out on the conventional detailed processing seismic stack migration sections for Da An Zhai Reservoir in Central Sichuan.
Again, through the comprehensive analysis and studies of drilling, geology and seismic, finally, the petroliferous (gas) phase modes in the area can be provided that is signal - wave microseimic phase of more continuous
waveform and strong energy doesn’t produce oil /gas, and compound - wave microseismic phase of poor continuous and weak energy is the optimal mode which expands our knowledge for Da An Zhai Reservoir in
Central Sichuan.

Key words: Reservoir, Seismic geology, Seismic wave, Analysis of seismic map, Phase, Oil/gas reservoir
