目的：充分利用先进的计算机技术，从三维角度来研究油气田的地下地质特征，建立地质模型，为全面认识和开发油气田提供重要依据。方法：文中吸收了国内外地质建模的新理论、新技术，并利用该技术对东濮凹陷中的最大气藏──文23气藏进行综合地质研究。结果：建立了该气藏的三维地质模型，从三维角度对气藏地质特征等进行了描述，并对气藏地质建模效果进行了分析。结论：气藏构造为复杂背斜，储层非均质性较强，利用三维地质建模技术解决了气藏研究中的问题，在油气田勘探开发研究中值得推广。
Objective: To make full use of advanced computer technology to study the underground geological features of oil and gas fields in three dimensions and to establish geological models to provide an important basis for the comprehensive understanding and development of oil and gas fields. Methods: This paper absorbs the new theories and technologies of geological modeling at home and abroad, and uses this technique to study the integrated geology of Wen-23 gas reservoir, the largest gas reservoir in Dongpu Depression. Results: The 3D geological model of the gas reservoir was established. The geological characteristics of the gas reservoir were described from the perspective of three dimensions. The geological modeling of the gas reservoir was also analyzed. Conclusion: The gas reservoirs are constructed with complex anticlines and strong reservoir heterogeneity. The problems in gas reservoirs are solved by using three-dimensional geological modeling techniques, which deserves promotion in the exploration and development of oil and gas fields.
