摘　　要：四川盆地西北部二叠系栖霞组地层埋藏深、储层厚度薄、非均质性强,且早期二维地震资料深层反射成像差、分辨率低,构造难以落实、储层预测精度低。为此,利用新一轮三维地震资料采集和处理联合攻关的地震资料,开展基于构造物理模拟的构造模式建立、古地貌恢复、基于正演模拟的地震属性分析、叠后地质统计学反演定量储层预测等技术攻关,逐步形成了复杂构造带深层地震资料关键解释技术系列。这些关键解释技术较好地解决了复杂构造带深层构造落实和薄储层预测等难题,明确了高产富集区,为勘探开发井位部署提供了有效的技术支撑,加快了该区深层碳酸盐岩天然气勘探开发步伐。Due to deep burial depth,thin reservoir thickness,strong heterogeneity,and the limitation of two-dimensional seismic data which have poor deep reflection imaging and low resolution,it is difficult to implement the deep complicated structure and predict reservoir.In order to solve these problems,we use 3D seismic data with new performed and processed in the study area.The exploration techniques,including structural physical modelling to establish structural style,the attribute analysis by forward modeling,and post-stack geostatistics inversion to quantitative predict reservoir etc.,are studied.A key deep geophysical interpretation technologyseries in the complex tectonic belt is formed.The key explanation technology used for solving the deep structure is carried out in the complex tectonic belt and thin reservoir prediction.It has been clear about the high yield,for exploration and development well placement provides effective technical support,to speed up the pace of the deep carbonate gas exploration and development in the study area.
