摘要:
复杂断块区勘探开发过程中常遇到地层产状井震不吻合、假断层、假构造等现象,导致构造解释偏差。为更好地分析产生这种现象的原因,得到更准确的构造储层信息,以实际工区地质特征为基础建立断层模型,应用波动方程二维正演模拟方法,重建断层系统的地震响应过程,剖析复杂断块区地震响应特征。正演模拟结果表明,断层两盘速度差异、断层倾角变化、断层平面间距远近等对地层、断层反射成像会产生影响,并可能引起假的地震反射。研究成果有效指导了地震资料在油田开发中后期实际生产中的应用。
Abstract:
In the process of exploration and development of complex fault block areas, there are often phenomena such as inconsistent well-seismic formation, false faults, and false structures, which cause structural interpretation deviations.In order to better analyze the causes of this phenomenon and obtain more accurate structural reservoir information,a fault model was established based on the geological characteristics of the actual work area, and a wave equation two-dimensional forward modeling method was used to reconstruct the seismic response process of the fault system, and analyze the seismic response characteristics of the complex fault block area.The results of seismic simulation show that the speed difference between the two plates of the fault, the change of the dip angle of the fault, the distance between the fault planes, etc. can affect the formation and the fault reflection imaging, and may cause false seismic reflections. The research results have effectively guided the application of seismic data in actual production in the middle and late stages of oilfield development.
