摘要

新沟油田以古近系新下Ⅱ油组中三套泥质灰岩、泥晶白云岩储层为主力勘探层,油气显示较为丰富,但层序地层发育特征及其对油气分布的影响不明。采用盐韵律测录井、地震响应特征分析和曲线频谱趋势属性分析技术两种方法,重新划分新下Ⅱ油组层序地层。研究区新下Ⅱ油组地层划分5个四级层序和多个准层序;通过曲线频谱趋势属性分析技术能够较好的应用于盐湖盆地层序地层划分,实现层序划分的自动化。
        Three sets of argillaceous limestone and dolomicrite reservoirs are the main prospecting strata in Paleogene Xinxia Ⅱ oil group in Xingou Oilfield, where oil and gas are rich but sequence stratigraphic development characteristics and its impact on oil and gas distribution are unknown. Salt rhythm logging technology and seismic response feature analysis and curve frequency spectrum tendency attributive analysis technology are sued to redistribute sequence stratum of Xinxia Ⅱ oil group. It is divided into five fourth-order sequences and multiple subsequences. Curve frequency spectrum tendency attributive analysis technology can be well applied to sequence stratigraphy classification in salt-lake basin to realize sequence division automation.
