大丰—兴化地区岩性分析
|
摘要
地震属性技术近几年发展很快,已广泛用于构造解释、储层预测、油藏描述等方面,然而在定量进行岩性识别方面还不够成熟。以大丰—兴化地区为例,利用钻井和三维地震资料进行精细标定,在精细构造解释的基础上进行属性提取和属性分析,优选一些岩性类属性定量地作岩性识别。通过研究发现,可以利用振幅属性很好地识别出火山岩、泥灰岩、砂岩和泥岩,并确定了它们在振幅属性上的分界线,与实际钻井情况吻合很好,为砂体预测和储层描述提供了非常好的证据。
The technology of seismic attribute has been improved a lot in the past few years,and has been widely used to structure interpretation,reservoir prediction,reservoir description,etc.However,it does not perform so well in lithology identification quantitatively.Taking Dafeng-Xinghua Area as an example,drilling and three-dimensional seismic data are used for fine calibration,some lithologic attributes are selected for lithology identification quantitatively by attribute collection and analysis on the basis of fine structure interpretation.It is found that amplitude attribute could be used to identify volcanic rock,marl,sandstone and mudstone,and their boundary lines in terms of amplitude attribute are confirmed,which matches well with actual drilling,providing very good evidence for sand prediction and reservoir prediction.
