摘要
苏北盆地古近系发育阜二段、阜四段两套富有机质泥页岩,油气显示丰富,是目前非常规油气勘探的重要方向。基于岩矿特征、储集空间类型及分布、储集物性等研究,综合评价了阜宁组泥页岩储层,总结了泥页岩裂缝的测井响应及地震响应特征,探索了泥页岩储层甜点识别和预测的技术方法,并在盐城凹陷阜二段和高邮凹陷阜四段开展了预测工作,取得了良好的效果。
The second and fourth members of Funing Formation are two sets of rich organic matter mud- shale in the Subei Basin,which show rich oil and gas and are the important direction of unconventional oil and gas exploration. Based on the study of rock characteristics,reservoir space type and distribution,and reservoir physical property,the article comprehensively evaluated the shale reservoirs of Funing Formation,summarized characteristics of logging and seismic response to the shale fractures,and explored recognition and prediction methods for the sweet spots of shale reservoir. The forecasting on shale reservoir sweet spots of the second member of Funing formation in Yancheng Sag and the fourth member of Funing formation in Gaoyou Sag has obtained good effects.
