摘　　要：目前,很多学者分别研究构造应力场、温度压力、断裂、有机质的成熟度等因素对油气运移的影响,但大多数学者是研究单一因素对油气运移聚集的影响,本文以松辽盆地中浅层为对象,研究上述各因素的影响结果、各因素共同效应。研究认为,松辽盆地南部油气藏的形成主要受第三系初期的喜山运动影响,本次构造运动带来第三次热流高峰,使青山口组大量生烃,构造应力和大量生烃产生的超压是油气运移的动力,以断层为油气运移的通道聚集成藏,主要成藏期是明水期末—第三纪。Recently, many scholars have studied factors that influence hydrocarbon migration, including tectonic stress field, temperature, pressure, faults, and organic matter maturity, etc. However, most researchers just consider one single influential factor. This paper, taking middle-shallow layer of Songliao basin as an example, studies the allied results affected by all these factors. The study suggests that the hydrocarbgon reservoir generation in southern Songliao basin is affected mainly by early Tertiary Himalayan movement. This tectonic movement introduces the 3rd heat flow peak, resulting substantial hydrocarbon generation in Qingshankou Formation. Tectonic stress and over pressure caused by substantial hydrocarbon generation are the dynamic force for hydrocarbon migration, and the faults are the migration channels for hydrocarbon accumulation. The main accumulation period is from the end of Mingshui period to Tertiary.
