摘要
简要地介绍了在吉尔嘎郎图油田进行第四纪沉积物磁性调查的情况及其结果。试验研究结果证实:油田存在着K,J_r,J_n、及I_k等多种磁性参量异常,并呈现综合异常状态;这些异常不但指出了进一步勘探的远景区,而且还反映出油田内油气活动的现状及历史;并说明了利用第四纪沉积物磁性调查方法直接找油气藏的可能性。
This paper introduces the work magnetic measurement in Quaternary sediments in Jiegalangtu oil field and its results. The research indicates that there are anomalies of k (mag-netic susceptibity), Jr(remanent magnetization), Jn (natural remanent magnetigation), Ix (Inclination of k1 axis of the magnitude ellipsoid of magnetic susceptibility anisotropy). These anomalies not only help to reveal the present and the past of oil and gas activities, but also point out some potential districts for future exploration. Our research suggests the possibility to search for oil and gas fields with direct magnetic measurement in Quaternary sediments.
