摘要
K V指纹技术是近年来在国内逐步受到重视的一种油气化探技术。利用测试得到的C5～C16 的大量烃类信息 ,可以发现深部油气垂向微渗漏在近地表形成的异常 ,判别烃源岩及储层 ,并进行油 (气 )源对比。文中以苏北盆地盐城凹陷某探区为例 ,从井中化探与地表化探两方面对该技术在判别烃源岩和储层 ,以及依据化探异常圈定勘探靶区方面进行了应用研究 。
The K-V fingerprint is a geochemical hydrocarbon exploration technique which has been increasingly emphasized in China recently. Based on C 5～C 16 data observed by K-V fingerprint, hydrocarbon anomalies in surface soil resulting from deep vertical microseepage can be delineated, source rocks and reservoirs may be evaluated, and oil (gas) source correlation can be made. An applied study of the K-V fingerprint technique has been carried out through both borehole and surface geochemical prospecting in Yancheng sag, North Jiangsu basin, including identification of source rock and reservoir and delineation of exploration target from geochemical anomaly. This application has resulted in better effects.
