文23气藏三维地质模型研究

Research of 3D Geologic Model in Wen 23 Gas Reservoir

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。

Researching into some oil-gas reservoir and building the geologic model with the advanced 3D technology of computer would provide important basis for its understanding and development. This paper absorbed the new theory and technology of geologic modeling at home and abroad, with which we studied the geologic features and built the 3D model of Wen 23 gas reservoir──the biggest gas reservoir in Dongpu Depression, then described the structure configuration, reservoir property and distribution of fluid at 3D, also, analysed the effctiveness of geologic modeling. The application of geologic modeling in Wen 23 gas reservoir solved many questions in the complex structure and reservoir. It's valuable to popularize in fault-block oil-gas reservoir.
