摘要
The features and exploration potential of the Permian tight oil in the Junggar Basin were analyzed and evaluated using outcrop,core and geochemical data etc. The enrichment of tight oil is controlled by the distribution of effective source rocks and dolomitic rocks,and the tight oil occurs in the entire strata vertically and spreads across large continuous areas horizontally.The Junggar Basin has four Permian tight oil distribution areas,Fencheng Formation in the Mahu sag,Lucaogou Formation in the Jimusaer sag,Pidiquan Formation in the Shazhang-Shishugou sag,and Lucaogou Formation in the Bogeda piedmont.A number of wells obtained oil flow in these areas,suggesting great resource potential and favorable targets for future exploration.
