摘要

摘要: 达尔其构造是二连盆地白音查干凹陷重要的含油构造。以地震主测线为格架,结合烃源岩、岩性、热流、测试分析资料为依据,采用正演法开展二维盆地模拟工作。重点开展充填史、热流史、成熟度史、生烃史、排烃史和运移聚集史分析。油藏主要分布在腾格尔组和都一段。达尔其西部鼻状构造,都一段油藏主要分布在白音断层下洼部位,腾格尔组油藏主要分布在白音断层以上的斜坡方向;达尔其东部鼻状构造,油藏主要分布在都一段,腾格尔组油藏分布范围局限,以构造高部位为主。达尔其油藏演化历史分为第一成藏期、第二成藏期、散失期和稳定期。油藏主要成藏期为第一聚集期,低部位油藏存在散失过程,腾格尔组油藏成藏历史较都一段复杂。南部斜坡带为石油运移的主要指向区,为重点勘探领域。

Abstract: The Daerqi structure is a very important oil-bearing structure in the Baiyinchagan Sag,the Erlian Basin.Based on seismic lines,hydrocarbon source rock,lithology,thermal stream and test data,a two dimensional forward model of the basin has been made.Histories of filling,thermal stream,maturity,hydrocarbon generation,discharge and migration are analyzed.Oil mainly deposits in the Tenggeer Formation and the lowest part of the Duhongmu Formation in the Daerqi structure.In the western nose of the Daerqi structure,oil in the lowest part of the Duhongmu Formation mostly locates below the Baiyin fault and oil in the Tenggeer Formation mostly locates upon the Baiyin fault.In the eastern nose of the Daerqi structure,oil mostly deposits in the lowest part of the Duhongmu Formation and oil in the Tenggeer Formation mostly locates in the higher structure.Accumulation evolution of the Daerqi structure can be divided into four periods:the first accumulation period,the second accumulation period,the scattering period and the stable period.The first accumulation period is the main accumulation period.Oil scatters in the lower position.Accumulation history of the Tenggeer Formation is more complicated than that of the lowest part of the Duhongmu Formation.The southern slope is the main target of petroleum migration and should be focused on.
