摘要
为改善川东北长兴-飞仙关组深层礁滩相储层地震识别及预测的可靠性,提出了几种储层识别的有效方法和步骤。①通过实际地震资料分析,并结合数值模拟技术,得到生物礁、鲕粒滩和礁滩复合体的地震响应特征,利用这些特征在地震记录上对储层进行识别;②利用礁滩复合体沉积物形成与演化的全局变化规律,来约束和控制礁滩地层地震反射的局部追踪和成图(即所谓的GRCTM方法),从而完成礁滩储层形态的三维精确成像;③利用地质、测井和地震资料的综合分析和基于波形分类的地震相分析,来实现礁滩储层的预测。
In order to improve the seismic identification and prediction of deep reef and shoal reservoirs in Changxing-Feixianguan formation strata,North-East Sichuan Basin,Some meaningful and efficient approaches or steps are proposed in this paper.The first one is the identification of organic reef and reef-oolitic shoal complex reservoirs on seismic records by using the seismic response characterizations from seismic simulation and real data analysis.The second is the accurate 3D images of reef-shoal complex reservoir shape based on GRCTM method which means using the global variation rule of reef complex deposition formation and evolution to control or constrain the local tracing and mapping of seismic reflections from the complex strata.The third is the reservoir prediction by integrated analysis of geology,well logs,seismic data and waveform-based seismic facies analysis.
