STUDY ABOUT THE REGULARITY OF HYDROCARBON MIGRATION AND ACCUMULATION IN SANGTAMU AREA, TARIM BASIN
塔里木盆地桑塔木地区油气聚集规律研究

Sangtamu region,which locates in the central of Lunnan low salience of the Tabei uplift in Tarim basin,is an important area where petroleum enriched and produced.By anatomizing development history of rift in Sangtamu area,the south rift and the north rift development segment,which are different in the west,the middle,and the east.During Hercynian and Himalayan,which are zero hours of hydrocarbon accumulation,rift of middle part and the east part were heavy activity,but the west part development was ill defined.This indicates the consanguinity among the rift development and hydrocarbon migration-accumulation.So resurveying regularity was brought forward: the resurveying regularity was controlled by differentia accumulation theory in horizontal direction and migration fractionation in elevation direction.
