| 摘 要： | 通过对洛阳-伊川地区三叠系基本石油地质条件的分析,认为三叠纪洛阳-伊川地区与鄂尔多斯盆地处于同一大型坳陷型湖盆,生储盖架构相似,烃源岩发育、厚度大、横向展布稳定、储层致密,且三叠系油气显示丰富,具致密砂岩油气藏形成的地质条件。结合对屯1井上三叠统椿树腰组工业天然气流分析,进一步明确了洛阳-伊川地区三叠系油气藏为具有低孔渗性、地层压力异常、油气呈"上油下气"倒置关系等特征的先成型致密砂岩油气藏,从而指出三叠系为洛阳-伊川地区下一步油气勘探的主攻层系,致密砂岩油气藏是该区勘探的主要方向。

| Abstract: | Research of the petroleum geological conditions indicates that Luoyang-Yichuan area is located in the same large depressed lacustrine basin with Ordos Basin in the Triassic.They have similar source-reservoir-caprock associations,thick and extensive source rocks,tight reservoir and active hydrocarbon shows in the Triassic.Therefore,the Luo-yang-Yichuan area has the geological conditions for accumulation of tight sand oil/gas.In combination with the analysis of industrial gas flow from the Upper Triassic Chunshuyao Formation in Well Tun 1,we believe that the Triassic reservoirs of the Luoyang-Yichuan area are pre-existing tight sandstone oil/gas reservoirs with low permeability,abnormal pressure,inverted oil-gas contact with oil in the upper and gas in the lower.The Triassic tight sandstone reservoirs are the main targets of petroleum exploration in Luoyang-Yichuan area in the future. |
