大牛地气田盒2+3段储层地质建模方法研究

通过对大牛地气田地质、储层及开发情况分析,在地质基础、测井综合解释、地震储层横向预测等研究基础上,充分利用已有地震、钻井、测井、试井及分析化验资料,结合控制约束的随机性建模方法,分别建立大牛地气田盒2+3段构造、岩相和属性模型,并对应生产实践检验模型可靠性,最终确定出适合大牛地气田盒2+3段的地质建模方法。

Study on reservoir modeling of H2+3 section in Daniudi gas field

After detailed analysis on the geological setting,reser- voir characteristics and development scenario and on the ba- sis of research on the integrated logging interpretation and the lateral prediction of reservoir through seismic data,avail- able seismic information,drilling,logging,well testing and laboratory analysis data are fully referred to establish the constrained arbitrary modeling method that is controlled by the assemblage of geological,geophysical and drilling data. After multiple times of calculation,the models of tectonics, lithology and attributes of H2 3 section in Daniudi gas field are obtained.Through the comparative analysis and the reli- ability test with the actual production,the optimized model- ing method compatible with the geological setting of Daniudi gas field is confirmed.
