【摘要】 地震属性技术是储层预测的重要手段,目前已有多种类型的地震属性参数可以提取和利用,但是单一地震属性分析与解释存在较强的多解性、不确定性。属性降维是通过K-L变换把属性空间的高维样本变成低维样本,降维后的地震属性更加具有代表性,更能反映地质特征,然后再将降维后的地震属性用于储层预测更加符合地质规律。通过地震属性降维方法对陆梁油田陆151井区侏罗系头屯河组油藏进行储层预测,其预测结果与部署的评价井在地质参数上符合程度较高,取得了较好的效果。更多还原

【Abstract】 Seismic attribute was an important method for reservoir prediction.At present there were many kinds of seismic attributes for extraction and application,but the single attribute analysis and interpretation were multi-explanations and uncertainty.In the reduction of dimensions of seismic attribute,attribute of high-dimensions samples was changed into low-dimensions by K-L transformation.It was better to represent and describe features of reservoir after dimensions reduction.It can be used to predict reservoir and the results are more in line with geological rules.Based on this method,Wellblock Lu-151 is taken as an example to predict reservoirs.The predicted results and geological parameters of evaluation are matched well and good results are achieved.更多还原
