利用航磁资料分析研究古冲沟及其分布规律

利用对原始航空磁测资料进行处理后而得到的方向导数和磁性基岩深度图等资料 ,结合钻井与地质资料总结归纳出东营凹陷地区古冲沟分布的磁场解释标志 ,分析推断出研究区内的古冲沟分布规律。经与地震资料对比验证 ,其结论基本吻合 ,为油气田的进一步开发提供有利的勘探远景区 ,对推测其它区域的古冲沟分布起到很大的类比和外推作用。

The Study of Paleogullies and Their Distribution Rules Using Aeromagnetic Data

Using magnetic derivative and magnetic basement rock depth plot processed from original aeromagnetic data and combining the analyses of artesian well data and geologic data, we summarized the sign of magnetic explanation of the paleogullies. We also analyzed and inferred the distribution rules for the paleogullies in the research area. Comparison with the results from the seismic profiles shows that the conclusions are basically in good agreement.The study will provide prospects for the development of oil and gas fields, and is of significance for the study of paleogullies in other regions.
