摘要
通过声波测井资料和地震速度谱资料的解释和处理,系统研究了德南洼陷的泥岩压实规律、过剩流体压力与烃类初次运移条件和烃源岩埋藏历史,对研究区处于未成熟低成熟阶段的石油初次运移条件进行了定性评价,认为Es3和Es4为主要的排烃层段。
By explianing and processing the sonic log and seismic velocity spectrum data, the paper makes a systematic research on the rule of mudstone compaction, abnormal fluid pressure, primary migration of hydrocarbon and burial history of source rock in the Denan depression. A qualitative evaluation is made for the condition of hydrocarbon primary migration of immature and lower mature petroleum. The authors propose that E s 3 and E s 4 is the main formation of hydrocarbon expulsion and that the two overpressure aeras, the south of study aera and the aera nearby Well De 6, are the main source aeras of hydrocarbon.
