松辽盆地齐家地区高台子致密油层包裹体古流体压力特征及其地质意义
THE FLUID INCLUSION PALEO PRESSURE CHARACTERISTICS AND GEOLOGICAL IMPLICATIONS OF GAOTAIZI TIGHT RESERVOIR IN QIJIA AREA OF SONGLIAO BASIN
摘要
Abstract
PVTx thermal dynamics simulation of reservoir fluid inclusions has been applied to restore trapping pressures by inclusion component,homogenization temperature and gas liquid ratio combined with simulation software.In Gaotaizi tight reservoir in Qijia area of Songliao Basin,the hydrocarbon charging events and the paleo fluid pressure are divided by CLSM,fluorescence microscopy and microthermometry,through which characteristics of different events of paleo fluid pressure are distinguished.The results indicate two stages of hydrocarbon charging in Qijia Area.The first charging occurred in upper Cretaceous Nenjiang late stage (79 ~75 Ma),with yellow fluorescence color.The second charging occurred in upper Cretaceous Mingshui stage (79 ~75 Ma),with yellow-green and blue-green fluorescence color.The paleo fluid pressures of two stages respectively are 16.13 ~16.97 MPa and 22.14 ~26.13 MPa.All the research findings are of great help to deepen the understanding of hydrocarbon accumulation patterns of the exploration area.关键词
