Reservoir formation conditions and accumulation laws in Mesozoic in Yuqi area

摘要: 以塔里木盆地北部于奇地区为例，综合利用基础地质、地球物理、地球化学、测井等手段，分析研究区内油气成藏条件及成藏模式。于奇地区成藏具有东、西及中分带的特点，油气成藏规律东西差异较为明显；结合已发现油气藏的解剖数据，提出了于奇地区中生界油气富集的控制因素，预测了于奇地区的有利勘探区，为下一步油气勘探提供依据。

Abstract: Taking the Yuqi area in the northern Tarim Basin as an example, with fundamental geology, physical geography, geochemistry and logging data, the paper analyzed petroleum accumulation condition and reservoir model in the study area. Reservoirs can be divided into east, west and central blocks in the Yuqi area, showing significant difference between east block and west block in reservoir formation. Associated with the history data of this petroleum reservoir, some controlling factors of petroleum accumulation were proposed and the favorable exploration area of Yuqi areas was forecasted. The results can provide evidences for further petroleum exploration.
