摘要

资料显示松辽盆地的石炭—二叠系具有较大的生烃潜力和油气资源前景,有望成为未来松辽盆地深层油气勘探突破的重点层系,但是,石炭—二叠系地层的分布无论在方法技术和认识方面仍存在较大的不确定性。因此,本文围绕沈阳地质调查中心位于西部斜坡带的黑富地1井部署了一条大地电磁测深剖面,通过野外试验优选了采集参数,获得了高质量的原始数据;通过数据分析、利用共轭梯度法反演获得了电性结构剖面,并结合钻井、地震等资料开展综合分析。结果表明,黑富地1井附近发育两条横向稳定展布的低阻层,其中第一套低阻层埋深在300~800 m之间,是白垩系地层高泥质含量地层的电性响应,第二套地层位于T5界面之下1.5~2.5 km之间,横向起伏幅度较小,结合钻井资料推测反映二叠系林西组泥岩层;并结合深层气体的主控因素,预测了油气有利部位。这些认识为松辽盆地石炭—二叠系油气资源的评价提供了可靠的地球物理依据和技术储备。

Abstract：

In recent years, more and more data show that the Songliao Basin has a large hydrocarbon generation potential and oil-gas resource prospect, and is expected to become the key stratigraphic horizon for the deep oil-gas exploration breakthrough in the Songliao Basin in the future. However, The distribution of the Carboniferous-Permian strata still has large uncertainties in terms of method, technology and understanding. In view of such a situation, the authors deployed a magnetotelluric sounding profile around the Heifudi- drill hole in the western slope zone of the Shenyang Geological Survey Center. The field parameters were used to optimize the acquisition parameters and thus high quality raw data were obtained. Through data analysis and conjugate gradient method, the electrical structural profiles were obtained and, in combination with drilling, seismic and other data, a comprehensive analysis was conducted. The results show that two horizontally stable low-resistance layers are developed near Heifudi-1 drill hole, and the first set of low-resistance layers is buried between 300 to 800 meters, which is the electrical property of the Cretaceous strata with high muddy content. In response, the second set of strata is located between 1.5 to 2.5km below the T5-Interface, and the lateral undulation is small. Combined with the drilling data, it is considered to reflect the mudstone strata of the Permian Linxi Formation. Combined with the main controlling factors of deep gas, the favorable zone of oil-gas has been predicted. These insights provide a reliable geophysical basis and technical reserve for the evaluation of the Carboniferous-Permian hydrocarbon resources in the Songliao Basin.
