摘要
大兴场地区栖霞组大面积发育受滩相控制的晶粒云岩及颗粒灰岩储层,其储层类型为裂缝-孔隙型。为了预测栖霞组储层发育有利区,在分析研究区地质特征,总结储层地震响应特征、测井响应特征基础上,对古地貌进行恢复,并选取敏感属性定性预测储层发育有利区;其次进行裂缝预测,找到小断裂及裂缝发育区;同时利用叠后地震属性进行烃类检测试验;最后综合以上的几种预测结果和构造成果综合预测栖霞组储层发育区。
Affected by shoal facies, the crystal dolomite and grain limestone reservoirs are widely developed at Qixia Formation, Daxingchang area. The reservoirs belong to fractured and porous ones. In the study, the geological features of study area were analyzed; the paleogeomophic restoration was carried on based on some characteristic of seismic response, well-logging response; sensitivity attributes were selected to predict a favorable reservoir development belt. Moreover, fracture was predicted, and small fractures and some fracture development areas might be found. At the same time, hydrocarbon detection was implemented by means of post-stack seismic attribute. Finally, the development belt of Qixia Formation could be predicted through the above results and structural achievements.
