Fault sealing models of complex fault- block oilfield

摘要

Fault-block oilfields are existing widely in eastern China. Because the law of oil accumulation in complex fault-block oilfields is decided by fault sealing properties, it is the key to analyse the fault sealing or not in qualitative and quantitative way so as to judge the validity of a trap. Through the research in Shengli oilfields, Jiangshu oilfields, Jidong oilfields and Bohai oilfields, which are typical complex fault-block oilfields in eastern China, we put forward the conception of fault sealing models.
