巴楚夏河工区的三维速度建模方法
|
摘要
本文结合巴楚夏河工区的实际情况,详细探讨了该区三维速度建模方法。此法以地震速度平衡建模思想为指导,以随机模拟法为基础,采用离散平滑插值技术构建三维离散空间建模。与其他建模方法相比,此法的建模步骤及应用效果具有以下优点:1采用由点到面到体的建模过程,充分细致地反映了三维空间离散结构;2在建模过程中提供了大量插值、数值模拟方法,保证了建模的可靠性;3充分利用测井与地震信息,保证了建模的准确性;4所求速度模型能准确反映速度空间变化规律。文中具体介绍了建模步骤。在巴楚夏河地区的应用结果表明,此法能够较好地解决地震资料处理与解释中的速度问题,尤其是复杂地区的速度问题,可为油气田勘探开发提供准确的速度资料。
Combining with real situation of Bachuxia river work zone,the paper discussed in detail the 3-D velocity model-building method in that area. Taking the model-building thought of seismic velocity equilibrium as a guide and random modeling as a basis,the method uses discrete smooth interpolation technique to construct 3-D discrete space model. In comparison with other model-building methods, the model-building steps and application effects of the method has following advantages: (1) the model-building process from points to plane to cubicity fully and finely reflects 3-D discrete space structure; (2)a great amount of interpolation and numeric modeling methods are provided during model building, which ensures the model-building reliability; (3) the logging and seismic information are fully used to ensure the model-building correctness: (4)the solved velocity model can correctly reflect the changing low of velocity space. The concrete model-building steps are introduced in the paper. The application results in Bachuxia river area show that the method can better solve the velocity issue in seismic data processing and interpretation, especially in complex areas,which can provide accurate velocity data for oil/gas field exploration.
