摘要
非震物化探油气勘探方法已成为特殊景观下油气勘探的重要组成部分。非震物化探油气勘探的方法较多,单一物化探指标往往不能满足高精度的勘探要求,多种方法综合分析确定油气有利区,可降低油气勘探成本与勘探风险,提高工作效率。本文研究了层次分析法与特征值分析法相结合的物化探综合油气评价方法。该方法在参考处理人员经验的基础上,结合不同指标异常之间的相关性,计算得到物化探指标信息与油气藏的综合关联度,进而圈定油气异常区。对鄂尔多斯盆地内某油气区的应用研究表明,该方法圈定的综合油气异常区与已知钻孔控制的油气有利区对应关系良好。该研究对非震物化探油气勘探方法的资料综合分析与解释具有借鉴意义。
Generally,one single non?seismic geophysical and geochemical method can not meet the requirements of oil exploration,and hence we need to use a variety of methods to carry out the comprehensive analysis and determine the favorable areas of oil and gas. In this paper,the authors studied the comprehensive evaluation of oil and gas exploration that combined the hierarchy analysis and the ei?genvalue analysis.The application in the Erdos Basin oil and gas zone shows that the oil and gas anomaly areas delineated by this meth?od has a good corresponding relationship with the known oil and gas enrichment areas controlled by drilling.
