摘要:

松科1井北孔是松辽盆地白垩系科学钻探工程的两个钻孔之一,位于松辽盆地北部中央坳陷区齐家古龙凹陷他拉哈向斜上。通过对松科1井北孔泰康组到嫩一段顶部连续取心资料的详细描述,建立松科1井北孔岩心剖面。识别出白云岩、火山灰、油页岩、灰质泥岩、泥灰岩5种特殊岩性,特殊岩性出现的总层数为73层,总厚度为708 m,分布在嫩二段、嫩三段、嫩四段、嫩五段和明二段中。对松科1井的精细岩心描述和对特殊岩性的识别是开展后续研究工作的基础。

Abstract:

CCSDSKIn borehole (China Cretaceous Continental Scientific DrillingSongkeⅠ—the north borehole) is the north one of the two drilling wells of the Cretaceous Scientific Drilling Project in Songliao Basin. It is located in Talaha syncline in Gulong sag of center depression, north Songliao Basin. Based on the detailed description of the cores from the Taikang Formation to the first member of the Nenjiang Formation in CCSDSKIn borehole, we have established the core section and identified five special lithological layers, including dolomite, volcanic ash, oil shale, lime mudstone and marl. The total number of special lithological layers is 73 with total thickness of 708 m. They distribute in the second to the fifth member of the Nenjiang Formation and the second member of the Mingshui Formation. The detailed description of the cores from CCSDSKIn borehole and the identification of special lithological layers will benefit the further studies.
