川东北元坝地区飞仙关组二段鲕滩储层预测
|
摘要
川东北元坝地区飞仙关组二段具有广阔的勘探潜力。本文在分析元坝地区飞仙关组二段鲕滩储集层地质特征的基础上,利用三维地震资料,进行储集层精细标定、储集层地质建模与正演,确定储集层的地震响应特征;采用古地貌分析、地震相划分及地震属性分析等手段,确定储集层发育的有利相带和储层宏观展布,并以此为基础,应用稀疏脉冲约束波阻抗反演对储集层孔隙度及有效厚度进行精细预测,建立了一套鲕滩储集层的预测方法,预测了元坝地区飞仙关组二段鲕滩储集层的分布,通过与已完钻井储层厚度及孔隙度的对比,证实了预测结果的正确性。
The second section of Feixianguan Formation of Yuanba area in the northeast Sichuan Basin has great potential of the petroleum exploration.Based on the geologic features of oolitic-beach reservoir, accurate reservoir calibration and geological reservoir modeling,we utilize 3Dseismic data to determine reservoir seismic response features.In order to predict favorable facies belts of reservoir growth and the macroscopic distribution of reservoir,we adopt paleogeomorphology analysis,seismic facies analysis and multi-attributes analysis.On this basis,we realize impedance inversion to accurately predict effective thickness of oolitic reservoirs and their porosity.So a prediction method for ooliticbeach reservoir is established and the distribution of oolitic-beach reservoir on the second section of Feixianguan Formation is predicted.Meanwhile, reservoir thickness and porosity from the finished wells confirm the accuracy of our predictions.
