找到大庆油田并投入开发已二十年。通过对油田的勘探开发和对松辽盆地其他地区的勘探,积累了丰富的资料,认识和初步掌握了一些石油地质规律。本文在总结大庆油田形成条件和油藏特征的基础上,根据松辽大型陆相断坳盆地特点,进一步总结坳陷期沉积的油气聚集规律,为在松辽和类似盆地寻找更多的油气田提供依据。
Daqing Oilfield has been found and put into development for 20 years. Through the exploration and development of oilfields and exploration of other areas in the Songliao Basin, a wealth of information has been accumulated, and some laws of petroleum geology have been recognized and initially mastered. On the basis of summarizing the formation conditions and reservoir characteristics of Daqing oilfield, the paper summarizes the accumulation of oil and gas in the depression during the depression period according to the characteristics of Songliao large-scale continental off-basin basin and provides a basis for finding more oil and gas fields in Songliao and similar basins in accordance with.
