| 摘 要： | 开发地震精细构造解释的基本任务是三维地震资料解释与实钻结果进行交互分析验证，及时指导井位调整，提高钻遇储层的成功率。针对松辽盆地新肇地区G634—63井区开发地震地质任务要求，摸索出一套适合本区特点的技术组合，取得较好的地质效果。在应用解释系统中放大地震剖面、时间切片、椅式切片和三维可视化等常规解释功能的基础上，结合精细层位标定、层面解释分析技术、地震相干数据分析技术和高分辨率波阻抗反演等多种技术开展小断层的研究，避免了1m～2m薄储层断失；应用地质统计学方法进行动态时深转换，提高密集井网区构造解释精度；进行全三维的层面和断面成图，指导复杂条件的井位调整；总结出构造发育特征与储层有效厚度分布的关系。 |

| Abstract: | The basic task of fine structure interpretation is the mutual verification of 3D seismic data interpretation and drilling result so as to guide wellsite adjustment and improve success rate of finding effective reservoir.In Songliao basin,a series of techniques, which are suitable for the G634-63 well block of Xinzhao area,have been used and some satisfactory geological results obtained. Fine calibration for horizon, bed plane analysis techniques,seismic coherence data analysis,high resolution impedance inversion and other techniques along with the conventional interpretation function in system, such as magnification seismic profile, timeslice, chair slice and 3D visualization etc.. are used to study small fault for avoiding the loss of 1 m~2 m thin reservoir.With the help of dynamic time-to-depth conversion statistics,we have improved the structure interpretation accuracy.Real 3D bed plane and fault plane maps are used to guide production well site adjustment in complex condition. The relation between tectonic feature and effective thickness of reservoir is summaried. |
| Keywords: | production seismics small fault thin reservoir fine structure interpretation |
