直接探寻油气藏的微磁环状异常法及在鄂尔多斯盆地的应用

利用物、化探方法检测油气产生的微观效应和异常,从而揭示地下是否有油气聚集,其特点是试图将油气藏与其相关的地球物理异常建立直接的联系,以达到寻找油气藏的目的.这些物化探方法与寻找油气圈闭的其它勘探技术的主要区别在于:不是通过研究圈闭,而是通过研究油气目的层自身或其伴生物、衍生物等去探测油气藏,这就是物化探直接探寻油气藏法.本文所应用的环状磁异常探测法就是此类方法,并将其应用于鄂尔多斯盆地油气预测.

The Micromagnetic Aureolr Exploration Strategy in Direct Detecting Oil Gas Field and the Application in Eerduosi Basin

The method of application of geophysics and geochemical exploration techiques to find out the microcosmic effect and abnormality in oil and gas field,which we called as geophysics and geochemical exploration techiques direct detecting reservoir.By using the method,we can disclosure whether there are oil gas gather in subsurface.The characteristic of the method is that,for seeking oil and gas field,it try to found direct relation between reservoir and geophysics abnormilty in oil and gas field.The primary difference between the method and other geophysics and geochemical exploration is: it does not detect oil and gas field by studying oil trap itself but oil gas stratum or derivant of oil gas stratum.The micromagnetic aureole exploration strategy of the article belongs to above-mentioned method,which we used to forecast oil and gas in EERDUOSI basin.
