摘要
在对地层层序划分、地震相分析、沉积相分布、沉积有机相分布以及成烃演化等方法深入研究的基础上,提出了一种以沉积相法为主,以地震相法、井点法、类比法为辅的烃源岩综合预测方法。应用此方法,按照步步优选的思路,采取由粗及细、由浅及深、由整体控制到重点解剖的程序,确定了松辽盆地北部深层徐家围子断陷沙河子组湖相暗色泥岩和煤层烃源岩的面积及厚度。
The stratigraphic sequence division method,seismic facies analysis and the methodology for the distribution of sedimentary facies,sedimentary organic facies and the evolution of hydrocarbon generation were analyzed. A synthetic prediction method for the distribution area and thickness of hydrocarbon source rocks was proposed. The sedimentary facies analysis was taken as the principal method,and the seismic facies analysis, well point method and analogy method were taken as the additional methods in the synthetic prediction method. According to the optimal mentality and technical program realized step by step, the distribution area and deposition thickness of hydrocarbon source rocks in Shahezi Formation of Xujiaweizi Depression in the north deep zone of Songliao Basin were determined with this method.
