Publish Date: 10 October 2016

摘要: 呼仁布其凹陷在下二叠统基底之上沉积了厚达4000 m的河湖相含煤、含油碎屑岩,具有良好的油气地质条件和资源前景。结合大地电磁测深法解译的断裂构造及地层展布,对南次凹土壤油气化探异常特征进行了研究和分析,探讨了呼仁布其凹陷的土壤油气化探异常模式,分析了化探异常成因类型。本次研究填补了该区化探资料空白,为研究区油气资源调查与评价提供了重要依据。

Abstract: Over 4000 meters of lacustrine face coal an d oil?bearing clastic rock are deposited above the lower Permian base rock in Hurenbuqi sag, suggesting a good prospect of oil and gas geological conditions and resources. In this paper, the authors discuss the a?nomaly pattern of soil hydrocarbon geochemical exploration based on the magnetotelluric sounding interpretation of fracture structure and stratigraphic distribution as well as anomaly characteristics of southern sag. The formation mechanism of the surface geochemical anoma?lies are investigated, and the geochemical anomaly models are analyzed. The results obtained by the authors will play an extremely im?portant role in oil and gas prospect evaluation.
