兴隆场Ⅰ-Ⅱ期连片三维飞二段鲕滩储层预测及应用效果

Feierduan Oolitic Reservoir Prediction and Its Application

下三叠统飞二鲕滩储层是兴隆场Ⅰ-Ⅱ期连片三维主要产层之一,为在该区寻找新的含气目标,针对飞二鲕滩储层建立了一套合理的预测方法。通过储层建模与正演总结研究区主要沉积相的地震识别标志,依据地震属性和波阻抗反演技术对飞仙关鲕滩储层进行了预测,并对储层的厚度和孔隙度进行定量化分析,认为本区鲕滩储层岩性圈闭成藏研究不深,下一步应结合已钻井的测试结果加强飞仙关组的成藏研究,以降低勘探开发的风险。

Feierduan oolitic reservoir of lower triassic is one of the mainⅠ-Ⅱstage continuous 3-dimensional production formations in Xinglongchang. A set of reasonable prediction methods are established aiming at Feierduan Oolitic reservoir to search the new gas-bearing target. Through reservoir modeling and forward modeling , this paper discusses Seismic identification mark of the main sedimentary facies in the research area, and predicts Feixianguan oolitic reservoir based on seismic attribution and wave impedance inversion technique and analyzes the reservoir thickness and porosity in a quantitative way, followed by the suggestion that the research on the hydrocarbon accumulation in Feixianguan Formation be strengthened combined with the test results of drilled wells to reduce the risk in exploration and development.
