【摘要】 锡林好来地区腾格尔组下段以薄互储层为特征,储层展布决定油气富集,需开展储层预测研究。通过加强基于地层岩性组合结构的地震反射特征正演模拟分析及准确的砂体标定,落实了地震反射信息的地质涵义,通过井控约束重构地震反演提高了地震识别薄储层的能力,降低了储层地震预测的多解性和不确定性,通过对主要含油砂体进行横向预测,为勘探开发井位部署提供了可靠依据。预测结果符合率高,推动了研究区构造岩性油气藏勘探获重大突破。更多还原

【Abstract】 The lower member of Tenggeer Formation in Xilinhaolai Area was thinner interbedding,where oil enrichment was determined by reservoir distribution,thus the reservoir prediction should be studied,it was important to predict reservoir.Based on the analysis of the strata litho-structure,the geologic meaning of the seismic reflection was confirmed after an exact sand-body calibration and forward modeling.The ability using seismic data to identify the thin reservoir was enhanced and the uncertainty of seismic prediction was reduced.After prediction of these main oil-bearing sand bodies,it provides a reliable base to the exploration and development.The result indicates that the prediction accordant rate is high and it is an important breakthrough of the exploration to the structure-litho reservoir in this area.更多还原
