| 摘 要： | 在三肇凹陷青一段源岩目前超压及其分布特征研究的基础上,利用声波时差资料根据泥岩破裂和愈合机理对其形成与演化过程进行了研究,得到青一段源岩有自身破裂和断裂破裂释放2种超压释放机制。利用自身破裂和断裂破裂分别对三肇凹陷青一段源岩超压释放次数恢复进行了研究,得到其先后共经历了8次超压释放,其中前5次超压释放是由泥岩自身破裂造成的,后3次超压释放是由断裂破裂造成的。由青一段源岩生烃期与其超压释放期比较得到,三肇地区青一段源岩自身破裂释放时期相对较早,不是烃向外排出的主要时期,断裂破裂造成的超压释放时期是烃向外排出的主要时期,即为明水组沉积末期和古近系沉积末期。

| Abstract: | On the basis of studying formation and evolution overpressure of K1qn1 sourcerock and its distribution in Sanzhao depression,according cracking and sealing mechanism of mudstone formation and evolution process of overpressure was studied by interval transit time.It was considered that there were 2 kinds of release mechnisms in K1qn1 sourcerock,which were release by cracking itself and by cracking of fault.By cracking of itself and cracking of fault,recovery of overpressure release periods of K1qn1 sourceroc... |
