作者在本文中通过浅层天然气勘探公司提供的几口探井砂岩体柱状图和井位坐标 ,建立研究地区的砂岩体空间分布数学模型 ,并在计算机上模拟了砂岩体的空间分布三维图及其等值线图。综合钻井、测井、地震资料充分说明所给出的砂岩体空间分布符合该地区的客观实际 ,效果满意 ,为该地区的油气勘探提供了可行的决策依据。
In this paper, through several histograms of well logging sandstone bodies and well location coordinates provided by shallow gas exploration companies, the author establishes a mathematical model of the spatial distribution of sandstone bodies in the study area and simulates the three-dimensional map of the sandstone body spatial distribution and its Contour map. Comprehensive drilling, logging, and seismic data fully demonstrate that the spatial distribution of sandstone bodies is in line with the objective reality of the area, and the results are satisfactory, which provides a feasible decision-making basis for oil and gas exploration in this area.
