动态能谱技术在川西须家河气藏的应用研究
|
摘要
川西坳陷须家河组气藏属于深层陆相致密碎屑岩气藏,具有致密、低孔渗、薄层交互、多层叠置和强非均质性的特点。长期以来,勘探成功率低,效益差。近年来,以高精度地震资料为主线,多学科协同,深入研究了须家河组的含气地震响应特征,充分利用地震资料信息,取得了一系列油气勘探开发的重大突破。在此期间,形成了基于地震波散射理论的动态能谱异常(Dynamic Register,简称:DR)含气性检测技术,此项技术在川西坳陷须家河组气藏勘探开发中取得了很好的效果。实践表明,川西坳陷须家河组含气砂岩储层具有高DR异常特征,应用这样的异常特征信息,可以较好地进行非均质致密砂岩储层的含气性检测。
The T3x gas reservoirs in west Sichuan Depression are deep terrestrial tight clastic rock gas reservoirs which are characterized by low permeability, thin inter-bed, superimposition of multi-layers, and strong heterogeneity. The success ratio in oil & gas exploration was low in the past. A series of breakthrough has been made recently because of multidisciplinary collaboration with emphasis on study of seismic responses for hydrocarbon-bearing T3x formations. A method call dynamic register (DR) was developed based on seismic wave scattering theory. Practice shows that T3x gas reservoirs are of high DR anomaly in western Sichuan Depression. DR index is a good indictor of tight heterogeneous gas reservoir.
