摘要 南(阳)襄(樊)盆地泌阳凹陷是一个油、碱共生的蒸发岩盆地,已探明规模石油与天然碱(NaHCO3和Na2CO3·3NaHCO3)地质储量。原油分为成熟油和未熟(低熟)油,成熟油储集于碎屑岩中,未熟(低熟)油储集于白云岩的裂缝和孔洞之中,而天然碱矿的围岩就是白云岩(裂缝和孔洞中也有天然碱赋存)。其地质特征与美国绿河盆地和犹英塔盆地十分相似,油碱共生受控于大地构造背景、古地貌、古地理、古气候、古沉积环境和物质来源等地质条件。

Abstract: A phenomenum of paragenesis of oil and trona (natural alkali, namely, NaHCO3 and Na2CO3·3NaHCO3) occurred in the Biyang Depression, Nan Xiang Basin in central China. The Nan-Xiang Basin was an evaporite basin during the Eogene, where the exploration proved certain scale oil and trona reserves. The crude oil could be divided into mature oil reserving in clastic reservoirs and immature (low mature) oil keeping in dolomite fractured and dissolved cavern reservoirs. Specially, the alkali layers were closely related to dolomites, namely, the wall rocks of the alkali deposits was these dolomites. There were similar geological conditions for the oil-trona paragenesis between the Biyang Depression and the Green River or the Uinta Basins in North America. The oil-trona paragenesis might be controlled by the tectono-paleogeomorphical evolution, paleogeography-paleogeoclimate situation, paleosedimentary environment, provenance and metallogenic material sources.
