摘要: 准噶尔盆地东部地区石炭系4个层组(下统塔木岗组、滴水泉组,上统巴塔玛依内山组、石钱滩组)均发育烃源岩。相对而言,塔木岗组及石钱滩组分布范围较有限,钻探程度较低,目前还难以准确评价;而下石炭统滴水泉组烃源岩厚度大,分布稳定,有机质丰度高、类型较好、生烃强度较高,目前已达到湿气演化阶段,是准北地区重要的源岩;与滴水泉组烃源岩相似,上石炭统巴塔玛依内山组分布广泛,生烃指标较好,目前已达到生油高峰,是准东南部北三台—吉木萨尔地区石炭系重要的源岩。五彩湾地区、北三台地区均找到了与这两套源岩有关的油气藏,表明了石炭系良好的勘探前景。

Abstract: Carboniferous strata of the east Junggar area can be divided into four formations:Tamugang Formation,Dishuiquan Formation,Batamayineishan Formation and Shiqiantan Formation.Source rocks are developed in all of the four formations.Distribution of the Tamugang Formation and Shiqiantan Formation are relatively limited,and their exploration degree are low,and so it is difficult to evaluate them accurately.However,the Dishuiquan Formation is a set of important source rocks with the advantages of big thickness,stable distribution,abundant organic materials,good organic types,and high hydrocarbon generation intensity.Similar to the Dishuiquan Formation,the Batamayineishan Formation of the upper Carboniferous is also extensively distributed and has a good hydrocarbon generation index,and it has entered the high hydrocarbon generation stage.Thus it is a set of important source rocks for the Beisantai and Jimusaer area of the southern east Junggar Basin.Oil and gas fields which have good correlations with the two sets source tocks are discovered in Wucaiwan and Beisantai,indicating a well exploration prospect in Carboniferous.

Key words: East Junggar, Carboniferous, source rocks, Dishuiquan Formation, Batamayineishan Formation
