Abstract: Oil basins in East China are depressions grown up on the basement of different ages,characterized by three principle features:(1) blockfaulting structures,(2)continental deposit,(3)isolation of sedimentary depressions.As early as 1961,while conducting prospecting in the Songliao Basin,we summed up that oil and gas migration is of short distance,generally less than 50 KM,oil and gas generation region mainly controls the distribution of oil and gas pool,and this rule has been time and again verified and developed.Later exploration in Huabei,Nanyang,Jianghan,Liaoho,Subei and other depressions,supported our idea that major oil and gas fields are mostly distributed in areas favourble for oil generation.
