| 摘 要： | 微量元素谱图油气评价技术是在引进俄罗斯地电化学油气勘探方法的基础上开发的一项含油气性及油气属性评价预测新技术。试验研究表明,油区内外土样电化学提取微量元素Ti、V、Cr、Mn、Co、Ni、Cu、Zn的ICP质谱特征存在特征差异。利用微量元素谱图特征在五谷城和姬塬地区进行了油气评价和有利目标预测。地电化学微量元素谱图相关系数异常与微量元素浓度异常及烃类异常有较好的配置关系,与自然电位和可控源音频大地电磁确定的有效砂体储层相对应。2001及2002年在五谷城和姬塬地区微量元素谱图油气评价预测的有利区内及附近钻获油流,证实了微量元素谱图油气评价在长庆岩性油藏勘探中的作用及有效性。 |

| Abstract: | Hydrocarbon prospect appraisal by trace element spectral diagram is a new geochemical technique, developed on the basis of Russian geoelectrochemical exploration methods. Field tests show that spectral diagrams of electrochemically extracted trace elements Ti,V,Cr,Mn,Co,Ni,Cu,Zn in soil samples from within and outside oil production area have distinct characteristics. Based on these differences of spectral diagrams of trace elements in soil samples and the correlation coefficients of the spectral diagrams with standard soil sample from oil-bearing area, the hydrocarbon prospects of the study area can be evaluated and delineated. By the correlation coefficient anomalies of trace element spectral diagram in soil samples one oil-bearing prospect in Wugucheng area, which is in consistent with results of alkane geochemical analysis and self-potential anomaly and audio-frequency magneto-telluric anomaly, and 3 oil - bearing prospects in Jiyuan area are predicted. In 2001 and 2002 the predicted oil-bearing prospects were verified by the following drilling wells. |
