摘要
Abstract
Hutubi gas field is a medium-sized condensate gas field newly discovered in the middle part of southern Junggar Basin.Based on feature of the regional stress and tectonic movement this paper reconstructs the evolution history of Hutubi anticline and analyzes comprehensively accumulation process and key control factors.Formation and evolution of Hutubi anticline is controlled by episodic compression stress,sediments compaction and layer slip.Strong regional SN stress during Late Cenozoic Era not only made hydrocarbon source rock,the Middle-Lower Jurassic coal system matured and over-matrured to produce large volume of gas but also led to extreme high pressure of the strata and open of fractures so as to provide gas source and passageway for Hutubi gas field.Taking the regionally horizontal compression SN stress,the extreme high pressure and open of the fractures as the main control factor is of guiding significance to development of Hutubi gas field and locating new gas field targets at south margin of Junggar Basin.关键词
