2000年以来马17井水位、气压观测资料分析
|
摘要
整理和分析2000年以后马17井的水位、气压观测资料,采用日极差法分析影响该井水体的能量变化;分别采用按时间分段数据的散点图和全时段滑动分析的方法,定性和定量地研究该井的固体潮效应及其特点;采用滑动的一阶线性回归的方法分析长时间段内水位与气压的关系,解释该井的气压效应特征;最后结合淮镇地震、文安地震、汶川地震前后该井水位观测数据变化现象,讨论该井水位的变化机理和变化特征,揭示其变化发展趋势,使马17井在今后的地震预测工作中发挥更大的作用。
In this paper the water level & pressure observation data of Ma-17 well since 2000 is collected and analyzed.First,the impact of energy changes on water of the well is analyzed using daily extremum difference method.Second,the earth tidal effect and its characteristics is studied qualitatively and quantitatively using scatter diagram of piecewise data according to time graphs and the method of analysis of all time sliding.Third,the relationship between water level and pressure in long time period is analyzed using the sliding first-order linear regression,and the characteristics of pressure effect is explained.Finally,based on the well water level observation data change phenomenon before and after the Huaizhen earthquake,Wen'an earthquake,Wenchuan earthquake,the mechanism of the changes and variations of water level is discussed,the changing trend of its development is explored in order to make Ma-17 well play a greater role in earthquake prediction work in future.
