基于测井约束的煤田物性参数反演

煤层的物性参数反演是煤田地震勘探的重要技术手段，用于指导煤炭资源的生产与开发。该方法使用地震数据预测煤层物性特征，并刻画煤层的空间变化。但是常规煤层物性参数反演方法因缺乏高低频信息，降低了煤层反演精度。为了提高煤层物性参数反演精度，将测井数据用于地震数据反演方法，提出了基于测井约束的煤层物性参数反演方法。以准噶尔盆地为研究对象，利用实际地震数据和测井数据对反演方法进行应用分析。实际地震数据应用结果表明，基于测井约束的煤田物性反演方法能够取得较好的反演效果。

Inversion of coalfield physical parameters based on logging constraints

The inversion of physical parameters of coal seams is an important technical means for coalfield seismic exploration，which is used to guide the production and development of coal resources.This method uses seismic data to predict the physical characteristics of coal seams and characterize the spatial changes of coal seams.However，the conventional coal seam physical parameter inversion method lacks high and low frequency information，which reduces the coal seam inversion accuracy.In order to improve the inversion accuracy of coal seam physical parameters，logging data was used in seismic data inversion method，and a coal seam physical parameter inversion method based on logging constraints was proposed.It was took Zhungeer Basin as the research object，used actual seismic data and logging data to analyze the application of inversion methods.The application results of actual seismic data showed that the coalfield physical property inversion method based on logging constraints could achieve better inversion results.
