准东白家海凸起侏罗系井-震统一层序地层格架建立

The unite framwork building of sequence strata consideration with well and seismic in Baijiahai arch of eastern Junggar basin

隐蔽油气藏已经成为准噶尔盆地油气储量增长的重要目标,白家海凸起区石油地质条件极其优越,侏罗系岩性油气藏勘探潜力巨大。以高分辨率层序地层学理论为指导,应用地质分析与地球物理技术相结合的方法,建立该区侏罗系井-震统一的层序地层格架,可准确揭示等时格架内的生储盖组合规律、提高油气勘探的预测能力,进而为探索准噶尔盆地隐蔽油气藏形成条件与分布规律起到积极的指导意义。

Subtle reservoirs have become the important factors for increased reserves in Junggar basin.The petroleum geological conditions are very good in Baijiahai salient and there is great exploration potential of lithologic hydrocarbon reservoir in Jurassic strat.Based on high resolution sequence stratigraphy, in combination with geology analysis and geophysics technology,the uniform sequence strata frame with well and seismic has been established,which can accurately reveal the combination regularity among source rock,reservoir stratum and cap rock,increase the predicting ability of petroleum exploration and thus provide the guidance for Junggar basin to discover subtle reservoirs.
