中文摘要：

四川盆地官渡地区茅口组为缝洞型储层，其储层的发育受断层、裂缝和溶蚀洞穴发育的控制。利用研究区最新采集处理的三维地震资料，通过地震资料品质分析，认为该资料具有较高的信噪比，偏移归位合理，目的层波组特征明显，能较好地解决构造问题。在合成记录标定的基础上，搭建格架剖面并进行人工解释，然后采用人机联合波形对比层位自动追踪技术进行全区层位解释，采用相干、倾角扫描以及层面光滑度分析技术进行断层平面组合分析，落实了研究区的构造特征和断层展布特征。根据对构造特征和断层展布特征的分析，指出官北构造东翼、官中和官南构造西翼为可能的缝洞型储层发育区。

英文摘要：

The Lower Permian Maokou Formation of the Guandu structure in South Sichuan Basin is a fractured-vuggy reservoir. The development of the reservoir is controlled by faults, fractures and cavities. Based on the latest acquisitive and processing data of 3 D seismic and the analysis of the quality of the seismic data, the authors believe that the data have a higher signal to noise ratio, a reasonable prestack time migration, and obvious characteristics of waves in the target layer, and so they can solve the problem of the structure easily. Based on the calibration of synthetic seismogram, the authors establish the framework section and do the artificial interpretation. Then they explain all the horizons, by using human-computer interaction during the waveform contrast in horizon auto tracking, do fine analyses of combination of fault plane by using the coherent, dipcanning and smoothness level analysis, and then recognize the characteristics of the struclure and distribution characteristics of the fault. Finally, based on the analysis of the characteristics of the structure and distribution characteristics of the fault, the authors point out that the east of the northern Guandu structure, the west of the central Guandu structure and the southern Guandu structure might be the area of fractured-vuggy reservoirs.
