X851井区测井约束反演方法及应用

该文论述了基于模型的测井约束反演方法的基本原理及技术流程,对测井约束地震反演中的关键技术环节作了探讨。同时由于地下情况的复杂性及反演资料的多解性,故对约束反演解决问题的能力做出了客观评价并提出提高反演效果的策略。该文对X851井区进行了测井约束反演研究,结合测井解释成果及反演结果对储层做出评价,预测了该区须四段砂体储层的空间展布特征。

Methods and application of Well Logging Constraint Seismic Formation Inversion in x851 well

This paper discusses the principles and method path of model-based well-log-constrained inversion,and makes a preliminary exploration into some important details in seismic inversion constrained by wells.Owing to the complexity of underground conditions and the ambiguity of inversion results,an objective evaluation is made to the problem-solving ability of inversion constrained by wells and advance some strategy to increase the effectiveness of the inversion.This paper studies well-log-constrained inversion in the X851 Well Logging,we combine logging explanations and inversion results,make a comprehensive evaluation to reservoir and predict characteristics of spatial distribution of the Xusi member sand body reservoir.
