三维地震勘探数据与实际数据初步对比分析

The 3-D Seismic Exploration Data and Practical Data Preliminary Comparison Research

近年来,随着物探设备及技术水平的发展提高,三维地震勘探技术逐渐走向商业化,但目前尚无统一标准来判定各物探单位数据的准确性。本文在地质条件相近的条件下,采用数理统计中的区间估计方法,将三维地震勘探的煤层底板标高数据与煤层开采后实际量测的底板标高数据进行统计与对比分析,计算所测数据相应的置信度与置信区间。通过统计分析定量的计算三维地震勘探数据的精确度,对各单位物探所测数据进行了有效检验。为生产单位选择精准的物探单位提供了有效的检验方法。

Recently years,with the increase of geophysical equipment and technology,3-dimensional seismic exploration gradually trend to commercialization.Units of technology and content,jagged interpretation methods to determine the standard unit of the accuracy of the data.Based on geological conditions of similar circumstances,using the mathematical statistics method,the interval estimation of three-dimensional seismic exploration of coal floor slab elevation data and actual elevation data statistics and comparative analysis,calculation and measurement data corresponding confidence interval,one is for production unit of choose exploration more accurate measurement unit,the second is the quantitative calculation of three-dimensional seismic exploration data accuracy.
