摘　　要：地震反演利用地震数据获得岩性和储层信息,是研究储层发育的一个重要手段。井资料是减少地震反演多解性的重要约束条件,但当大部分工区井资料缺失时,研究地震反演约束条件具有重要的实用价值和现实意义。基于约束稀疏脉冲原理,充分利用过三维工区的二维测线和井资料进行约束,实现了无井资料工区的反演工作。通过钻井验证,该方法的定性预测结果可靠,与实际情况差异较小。相较于传统方法,该方法理论依据充分,反演结果可靠性高,具有一定的推广价值。The application of seismic inversion was to use seismic data to obtain the lithology and reservoir information.It was an important means to study the development of reservoirs.The well data were an important constraint to reduce the ambiguity of seismic inversion,but when faced with a lack of well data in certain area,it had practical value and realistic significance to study the seismic inversion constrained conditions.Based on the principle of constrained sparse pulse,the 2D seismic data and well data were fully used for the constraint,and the inversion was realized in the area without well data.The result of the inversion is verified by drilling information,and the qualitative prediction based on this method is reliable.This method has sufficient theoretical basis and reliable results.It is valuable for popularization.
