模拟退火随机地震反演技术在新民东-长春岭地区的应用
|
摘要
模拟退火随机地震反演方法是一项用于油田勘探和储层预测及油气识别的重要手段。为了解决新民东-长春岭地区泉一段储层空间变化,通过低频地质模型、约束稀疏脉冲中频反演和模拟退火随机地震高频反演的融合,实现了不同频率范围内反演结果的处理。有效解决了新民东-长春岭地区储层预测工作。阐明了含气层段砂体的分布范围和空间展布形态,纵向上为多套砂岩叠置,平面上表现为多期的特点,物源以西南向为主,反演剖面上呈条带状发育或透镜状的砂体表现为垂直物源或斜交物源方向,呈前积结构的反演剖面表现为顺物源方向。利用模拟退火随机反演有利于指导勘探初期对含气储层特征的认识,为以后部署井位提供强有力的佐证。
Stochastic inversion method of simulated anneal is applied in oil field exploration,improving reservoir prediction precision and oil-gas identification.In order to understand the spatial changes of reservoir of the 1st member of Quantou formation in the eastern Xinmin-Changchunling area,combining low-frequency geological model,constrained sparse spike intermediate frequency inversion and stochastic high-frequency seismic inversion method of simulated anneal,Dealing with the inversion results of different frequency and resolving the problems of reservoir prediction in the eastern Xinmin-Changchunling area,the distribution and spatial morphology of sand bodies of gas-bearing formation is illustrated,occurring as overlapped sandstones vertically,multi-stages in plan,and SW sources.On inversion section the ribbon-like or lenticular sandstones are vertical or inclined to source orientation,while on inversion section with progradation configuration parallel to source orientation.This method is useful to understand the gas-boring reservoir character during early exploration period and to allocate boreholes.
