川东高陡构造石炭系储层预测试验

Prediction Test of Carboniferous Reservoir in Steep Structure Region of Eastern Sichuan Province

针对川东地区高陡构造，石炭系储层埋藏很深，地震反射波信噪比低等特点．本文提出了一套利用地震资料进行气藏预测的方法，并用此方法对二条剖面进行了学习和预测的试验，获得了较好的效果．其中特别提出了模型法归位计算，经钻探检验，对于构造归位和预测点归位两类问题的计算，均取得很好的效果．

In view of the features of steep structure, deep carboniferous reservoir and the low signal noise ratio of seismic reflection wave in Eastern Sichuan region, this paper presents the method of predicting gas reservoir with seismic data, and makes a study and prediction experiment on the to seismic profiles by this method, and acquires good results. Besides this pape specially introduces the model migration calculation method. Through drilling tests, it proves that this calculation method can be effectively used to ccalculate the two problems of structure migration and prediction point position migration.
