柴窝堡地区时频电磁测线解释研究
Interpretation of Time-Frequency Electromagnetic Survey Lines in the Chaiwopu Area

准噶尔盆地柴窝堡地区具有较好的油气勘探前景，但该地区以往油气勘探程度较低，控制程度不均衡，存在地质结构、烃源层分布及构造特征等认识不清的问题，进而制约了对该地区的勘探潜力的认识。本文在建立地层电性模版的基础上，明确芦草沟组与下伏地层有明显电性界面，并对14条时频电磁测线进行处理解释研究，联合时间域与频率域进行优势互补，提高了目标探测能力，绘制芦草沟组底部埋深平面图，进一步指导柴窝堡地区的勘探方向。
Chaiwopu area in the Junggar Basin has good oil and gas exploration prospects. However, the level of oil and gas exploration in the region was relatively low in the past and the degree of control was uneven. There were problems with unclear understanding of geological structure, distribution of hydrocarbon source layers, and structural characteristics, which further restricted the understanding of the exploration potential of the region. On the basis of establishing a stratigraphic electrical template, this article clarifies that there is a clear electrical interface between the Lucaogou Formation and the underlying strata. Processing and interpretation research were conducted on 14 time-frequency electromagnetic survey lines, combining the advantages of time and frequency domains to improve target detection capabilities. A plan of the burial depth at the bottom of the Lucaogou Formation was drawn to further guide the exploration direction in the Chaiwobao area.
