摘要
利用地震多属性分析技术,可以对地震数据进行各种数学、物理变换,提取出包含其中的岩性、含油气性、物性信息,为含油气储层预测提供技术支持,使地震属性模式识别技术在油气储层预测中得到了广泛的应用。在地震属性优选的基础上,应用多属性聚类分析技术,实现地震多属性与储层信息的结合,使特定的聚类区能可靠地反映含油气分布,同时聚类分析结果也可成功地预测研究区ZH2_1气组的有利含气区,为进一步勘探开发提供了目标区域。
Seismic attributes analysis technology,which uses mathematic and physical conversion into seismic data interpretation,is adopted to extract the information about lithology,gas-oil occurrence and physical property of a reservoir so as to provide technological support to gas-oil reservoir prediction.The pattern recognition technology of Seismic attributes has also been widely applied in the oil and gas reservoir prediction.Upon selection of optimal seismic attributes,we used the multi-attribute clustering technology to establish the connection between multi-attributes and reservoir information.The specific cluster area may indicate an oil and gas rich area.We made prediction for the gas group of ZH2_1 in the Zhu-3 Depression.Favorable target area was selected for further exploration and development.
