其他摘要 | In this paper, some questions are discussed including the Mesozoic and Tertiary sequential stratigraphy, sedimentary systems, tectonic evolution, structural styles, the distribution of source rocks, the quantity of petroleum resources and the forming mode of oil and gas reservoir, and so on. Firstly, the Mesozoic and Tertiary stratigraphic framework of the Jiyuan Depression are build with the information of outcrop, drilling and seism; the 8 third-order sequences are studied systematically with the method of seismic stratigraphy and the characters of the Mesozoic and Tertiary sedimentary system are illustrated in the first place. Secondly, the T7, T8, T9 structural maps of the whole depression are drew with new and old seismic information, the times and period of development of the faults are studied in the Jiyuan Depression and the style of the local structural trap of different structural layer with the balanced cross sections and discovers the controlling factors of the different local structural movement to sedimentation and oil and gas geology; Lastly, the forming conditions of oil and gas reservoir and the distribution of oil and gas are studied systematically with many new methods and gains the original achievements as follows: l.Base on the data of seismic,log,drilling and core, Mesozoic and Cenozoic are divided into 4 super-sequences and 8 sequences with the method of high resolution sequence stratigraphy. 2.Measuring the fission-trace of apatite of the Mesozoic and Tertiary sandstone, reviewing the paleo-geothermal gradients of the different development stages of structural characters and evaluating correctly the history of organic materials transforming into hydrocarbon in source rocks. 3. Measuring the temperature of inclusion of hydrocarbon-bearing sandstone and non-hydrocarbon-bearing sandstone in Deng-2 well, analyzing the biomarker out and in the inclusions, and discovering effectively the reasons and the developing course of Tertiary oil and gas reservoir. 4.Studying systematically the sedimentary system with seismic stratigraphy and sequential stratigraphy and providing the reliable foundations for the oil and gas geological estimation in the Jiyuan Depression. 5.Calculating the amount of the oil and gas reservoir with the method of basin-simulation, discussing the mode of structural lithofacies and the forming mode of oil and gas reservoir and foreshadowing the object of oil and gas exploration. |
