摘　　要：在地质物探领域中,对地质压力环境的准确重构,构建地球的压力和温度的物理参数的关系模型,为提高地质勘探的技术水平提供支撑。传统的地质压力环境重构算法采用三角剖分和数据内插的栅格网最小对角线差值方法,算法在重叠区域内产生种子点分布不均匀,环境压力重构精度不高。提出一种基于流数据分数维提取的地质压力环境重构方法,构建的地质的流数据分数维特征中包含着地质内部的相关信息,得到地壳的压力结构数学模型构建目标函数以环境温度、地质勘探井内压力、地质勘探井外压力为研究对象,构建地质物探井场,进行井间串接,形成构造解释散点数据模拟,构造压力参数相互关系的数学模型并进行仿真实验。使用实际采集的环境数据验证了计算结果的正确性,仿真结果表明,该模型对地质压力环境的重构拟合效果较好,为地质勘探提供了准确的数据基础。In the geological geophysical field, accurate reconstruction of geological pressure environment, the relationship model of pressure and temperature of the physical parameters of the earth building, to provide support for improving the technical level of geological exploration. Geological pressure environment reconstruction algorithm using the traditional grid network minimum diagonal difference triangulation method and data interpolation algorithm to produce seed, the nonuniform distribution in the overlap area of environmental pressure reconstruction accuracy is not high. Put forward a kind of geological pressure environment reconstruction method of Fractional Dimension Extraction Based on data stream, data stream fractal dimension characteristics of geological construction contains the information related to geological internal pressure, get the crust structure mathematical model is constructed with the objective function of the environmental temperature, geological prospecting, geological exploration well outside the pressure within the pressure as the object of study, con- struction the geophysical well site, was well connected in series between the structural interpretation, formation of scattered point data simulation, mathematical model of the relationship between tectonic stress parameters and simulation experiments. Using the actual collected environmental data verify the correctness of the simulation results, the simulation results show that, the model fitting effect is better reconstruction of geological pressure environment, provides accurate data base for geological exploration.
