摘要: 对塔里木盆地台盆区中1井和中11井的有机质成熟度演化规律分析发现,同处于台盆区的2口探井距离仅约13km,地层演化和构造特征相似,其有机质演化规律却截然不同。对其岩性特征和有机质演化的对比表明,发生有机质演化突变之处正是火山物质开始增多的地方,这说明火山作用的存在导致了有机质演化规律的突变。这2口井也可以作为火山作用对有机质演化规律产生影响的范例。

Abstract: The evolutions of organic matters of Zhong-1 and Zhong-11 wells in Tarim Basin are different,although they are located in the same basin with a distance of 13 kilometers and have the same sequences and structures.The strata characteristics and the evolution of organic matters indicate that the abrupt changing point is in the place where the content of tuff starts increasing.It shows that the igneous intrusion caused the abrupt change of the organic matters in both wells.Both wells can be considered as a typical case of igneous intrusion affecting evolution of organic matters.

Key words: Tarim Basin organic matter evolution igneous intrusion igneous matters tuff content
