【摘要】：在松辽盆地白垩纪大陆科学钻探松科2井实施前,以钻井地质设计为基础,结合区域地层特征、地球物理资料和邻井钻探结果,参照油气勘探生产标准和经验,对松科2井钻遇主要界面深度进行预测,建立基本框架,同时预测全井段岩性序列、可能的油气水情况和故障层段,最终建立松科2井综合模拟柱状图。各主要地层界面预测深度为:嫩江组二段顶面(T_06)950m,姚家组顶面(T_1)1 245m,泉头组顶面(T_2)1 680m,登娄库组顶面(T_3)2 530m,营城组顶面(T_4)2 965m,沙河子组顶面(T_4-1)3 320m,火石岭组顶面(T_4-2)5 670m,基底顶面(T_5)6 240 m。岩性剖面的预测主要分为两部分:(1)T_4-1之上参考邻井宋深3井钻遇岩性序列;(2)T_4-1之下则根据地震剖面、其他钻遇相当层位的邻井和区域地层特征综合预测。主要目的层岩性特征如下:营城组上部为粗砂岩、砾岩、砂砾岩,下部为厚层凝灰岩、安山玄武岩、流纹岩夹泥岩,底部为砾岩;沙河子组为泥岩夹煤线、细砂岩、粉砂岩和泥质粉砂岩;火石岭组上部为凝灰岩、泥岩、英安岩和安山岩,下部为泥岩夹细-粉砂岩,含煤;基底为极低级或高级成岩的石炭—二叠系沉积地层。松科2井模拟柱状图是钻探工程施工的主要依据,同时也为其他科学钻探工程模拟柱状图的编制提供借鉴。
[Abstract]:Before the Cretaceous continental scientific drilling of Songke 2 well in Songliao Basin, based on drilling geological design, combined with regional stratigraphic characteristics, geophysical data and drilling results of adjacent wells, oil and gas exploration production standards and experiences were consulted. The main interface depth of Songke 2 well is predicted, the basic frame is established, the lithology sequence, the possible oil, gas and water situation and the fault zone of the whole well are predicted at the same time. Finally, the synthetic simulation histogram of Songke 2 well is established. The prediction depth of the main formation interface is as follows: the top surface of the second member of Nenjiang formation is T06D 950m, and the top surface of Yao formation is 1 245m. The top surface of Quantou group was 1 680 m, the top surface of Denglouku group was 3 530 m, and the top surface of Yingcheng group was T 4 or 2 965 m. The top surface of Shahezi formation is 3 320m, and the top surface of Huoshiling formation is 5 670m. The prediction of lithologic profile is mainly divided into two parts: 1 / 1 and T4-1 with reference to the lithologic sequence of the adjacent well Songshen 3; The lithologic characteristics of the main target strata are as follows: the upper part of Yingcheng formation is composed of coarse sandstone, conglomerate and sandy gravel. The lower part is thick tuff, Anshan basalt, rhyolite intercalated mudstone, and the bottom is conglomerate. The Shahezi formation is composed of mudstone, fine sandstone, siltstone and argillaceous siltstone. The upper part of Huosiling formation is tuff, mudstone, dolomite and andesite, and the lower part is mudstone with fine siltstone and coal. The basement is a very low or high grade diagenetic Carboniferous and Permian sedimentary strata. The simulated histogram of Songke 2 well is the main basis of drilling construction, and it also provides reference for the compilation of simulation histogram of other scientific drilling projects.
