摘　　要：洛阳-伊川盆地是南阳油田近期油气勘探的新地区和新领域之一,主要勘探目的层系为中生界三叠系.研究认为,该区三叠系埋藏较浅,残存厚度大,分布面积广,其中暗色泥岩发育,具有一定的生油潜力.并且盆地的构造演化对地层的保存、构造发育、油气分布以及油气藏的形成有明显的控制作用.因此明确了该区下步油气勘探的方向和目标.Luoyang Yichuan basin,tectonically located on the southwest margin of North China platform,developed from the end of Indosinian movement,is one of the new exploration areas for oil and gas in Henan Oilfield.Mesozoic Triassic strata are the key target for exploration.Research has proved that the Triassic series,with its shallow burial,large residual thickness,vast distribution area and developed dark argillite,are potential for oil generation.The stratigraphic preservation,structural development,oil distribution,and oil and gas formation are dominated by the tectonic evolution of the basin,thus it determines the direction for oil gas exploration.
