| 摘 要： | 呼图壁气田是新疆准噶尔盆地南缘中段发现的第一个中型凝析气田。文章从区域构造应力特征及构造运动方式入手,重建了呼图壁背斜构造演化历史,综合分析了呼图壁气田成藏过程和成藏的关键控制因素。结果表明,呼图壁背斜构造形成演化,受幕式挤压应力、沉积压实作用及滑脱层的共同控制。同时,晚新生代的区域强烈SN向挤压应力不仅使得中下侏罗统煤系烃源岩迅速达到高-过成熟阶段并大量生气,而且造成地层异常高压以及断裂的开启,进而为呼图壁气田的形成提供气源和通道。而SN向水平区域构造挤压应力、异常高压及断裂是呼图壁气田成藏的主控因素。此认识对于呼图壁气田的开发、利用,以及在准噶尔盆地南缘寻找新的天然气勘探耙区,都具有指导意义。

| 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. |
