断层模型约束反演在MTH地区煤层横向预测中应用研究

The Study on Faults Model Constrained Inversion of Coal Seam Transversal Prediction in MTH

利用相干体确定断层平面的走向特征,在剖面上采用井点处断点引导小断层解释,准确落实其空间位置,并建立精细的断层模型,在此基础上,利用断层约束反演技术,进行煤层的横向预测。MTH地区实例表明,基于断层模型约束反演技术的煤层横向预测方法,可精细描述煤层变薄带、分叉合并带、厚度变化等赋煤状态。

This paper determines the fault tendency according to the coherent body.Well break point on the profile is used to guide small faults explanation.Its spatial position is ascertained accurately and elaborate fault model is established.The fault model constrained inversion is used to predict the horizontal tendency of coal seam.The examples in MTH show that the faults model constrained inversion of coal seam transversal prediction can describe the thin belt,crossed and merged belt and thickness variation of coal seam in detail.
