【摘要】 南堡凹陷4号构造带断裂发育,既发育沟通烃源岩的深断裂,也发育沟通浅层圈闭的次级断裂。综合利用地震、测井、岩性等资料分析断层的空间展布,计算蛤坨断层的生长指数和断层泥比率(SGR),分析断层的活动性、封堵性,评价其输导性能,并结合其与烃源岩生排烃期的匹配关系研究断裂与油气运移、聚集的关系及控制规律。在典型油气藏剖面解剖的基础上,建立了4号构造带油气运聚成藏模式。更多还原

【Abstract】 Faults are well developed in 4th structural belt of Nanpu Depression,among which there are not only deep faults linking hydrocarbon source rocks and traps,but also the associated faults that can reach shallow reservoirs.Based on the analysis results of seismic,logging and oil-testing data,the spatial distribution of faults have been analyzed,the growth index of faults and Shale Gouge Ration(SGR) are calculated.In addition,evaluation has been done on the activity of faults,the sealing and transportation capability of faults.Combined with the study on the matching relationship between the fault activity with hydrocarbon generation and expulsion,analyzed with modeling results,the relationship between faults with hydrocarbon migration and accumulation,and the control roles of the these faults on hydrocarbon migration and accumulation have been studied thoroughly.Finally,based on the analysis of the typical oil and gas reservoir profiles,the model of hydrocarbon migration and accumulation of the 4th structural belt has been constructed.更多还原
