SANDSTONE OF SIFANGTAI FORMATION IN THE WESTERN SLOPE OF SONGLIAO BASIN: Relation Between Hydrocarbon Fluid Characteristics and Uranium Mineralization
-
摘要:
通过对松辽盆地西部斜坡区四方台组33个砂岩样品的酸解烃分析，探讨了酸解烃中烃类气体组成特征、成因及来源，并结合该地区铀矿化地质特征初步分析了烃类流体与砂岩型铀成矿关系.酸解烃中气体组成特征参数C1/ΣC、C1/C2+、C2/iC4、C2/C3、iC4/nC4、iC5/nC5特征表明，四方台组底部砂岩中烃类气体为有机成因的油气型，烃类气主要处于成熟-高成熟阶段，是原油裂解气和原油伴生的混合气，它们主要沿盖层断裂运移到四方台组底部砂岩中.西部斜坡区四方台组含铀砂岩中烃类流体含量普遍增高，表明该区四方台组铀矿化与烃类气体关系密切.四方台组底部靠近沟通油气田的盖层断裂附近是西部斜坡区砂岩型铀矿找矿的重点地区.
Abstract:By analyzing the acidolysis hydrocarbon in 33 sandstone samples from Sifangtai Formation in the western slope of Songliao Basin, the paper discusses the composition, genesis and origin of hydrocarbon gas, and preliminarily analyzes the relation between hydrocarbon fluids and sandstone-type uranium metallogenesis combined with the geological characteristics of uranium mineralization in the area. The characteristic parameters of C1/ΣC, C1/C2+, C2/iC4, C2/C3, iC4/nC4 and iC5/nC5 for gas compositions in acidolysis hydrocarbon show that the hydrocarbon gas in the bottom sandstone of Sifangtai Formation is of organic origin, mainly in the maturity-high maturity stage, which are crude oil cracking gas and associated mixture gas, migrating to the bottom sandstone along superficial faults. The content of hydrocarbon fluids in uranium-bearing sandstone of Sifangtai Formation is generally increased, indicating the uranium mineralization is closely related to hydrocarbon gases. The place near the superficial fault connecting the bottom of Sifangtai Formation and oil-gas field is the key area for sandstone-type uranium deposit prospecting in the western slope.
