摘要
通过开展烃源岩分布及盆地油气形成机理的研究,为松辽盆地石炭-二叠系下一步的油气资源勘探及评价打下坚实基础。经过对前人资料的大量搜集、整理及总结,利用岩石热解等有机地球化学方法,以烃源岩为重点研究对象,对区内代表性钻井杜101井及四深1井进行了烃源岩评价,同时就构造体系对烃源岩的展布控制进行了初探。结果表明,松辽盆地石炭-二叠系仍具有一定的生烃潜力,从烃源岩分布来看,均明显受到了来自于华夏构造体系的控制并在后期遭受改造,局部地区受到来自于纬向构造体系的控制。
By studying the mechanism of source rock distribution and basins hydrocarbon formation it laid a solid foundation for the next oil and gas exploration and evaluation in Carboniferous and Permian of Songliao Basin Through the collection and summing up of predecessorsresearch results,by using the geochemical methods of rock pyrolysis and etc,the source rocks in the represented wells such as Well Du 101 and Well Sishen in the area were evaluated by taking the source rock study as a focused object,and the control of tectonic system on the source rock distribution was preliminarily studied.The result shows that the Carboniferous and Permian Systems in the area have certain potential of hydrocarbon genesis,and seeing from the source rock distribution,they are all controlled by Cathaysian Tectonic System and they are reconstructed at the late stage and locally they are controlled by Latitudinal Tectonic System.
