摘要： 渤东低凸起南段油气横向输导路径和输导能力的不确定性影响成藏模式的建立及新近系的勘探。综合利用钻井、测井资料，通过地震属性提取、岩芯观察等方法，对研究区油气输导条件进行分析，研究认为馆陶组骨架砂体横向输导受限于深入烃源岩且长期活动断层的发育程度以及自身含砂量，而火山岩潜山顶部不整合面的输导层盖层配置关系好，半风化岩石原生与次生孔、缝发育，且潜山以缓坡倾末端的形式延伸至深凹区，是主要的油气横向输导路径。在建立研究区成藏模式基础上，得出油气横向输导能力与潜山输导脊与烃源岩的接触长度、输导脊的倾角、输导脊之上的圈闭面积有关，并建立半风化岩石输导系数定量表征油气横向输导能力，指导新近系实际勘探。

Abstract: Uncertainty about the lateral passage and migration capability of hydrocarbon in the southern part of the Bodong Low Uplift influences the establishment of a reservoir-forming model, as well as Neogene exploration. Based on the well drilling and logging data, together with the extraction of seismic attributes and the observation of the rock core, hydrocarbon migration was analyzed in the study area. This study concludes that the lateral passage of a sand body in the Guantao Group was subject to the degree of development of a long-lived fault embedded in the hydrocarbon source rock, and its sand-carrying capacity. The passage layer and cover layer at the surface of the unconformity at the top of a buried hill of volcanic rock have a good configuration relationship. The semi-weathered rock has developed primary and secondary pores and fractures, and the buried hill extends to a deep depressional area at the end of the ramp, which is the main lateral passage for hydrocarbon. Based on the establishment of a reservoir-forming model, the lateral migration capability is affected by the contact length between the migration ridge of the carrier ridge of the buried hill and the source rock, the dip angle of the ridge, and the trap area on the ridge. A migration index of semi-weathered rock was established to reflect quantitatively the lateral accumulation capacity, which facilitates practical Neogene exploration.

Key words: southern part of Bodong Low Uplift, Neogene exploration, hydrocarbon lateral migration, buried hill of volcanic rock, semi-weathered rock in unconformity, quantitative evaluation
