Seismic acquisition technologies in Shengli Oilfield have evolved from 2D

conventional 3D

and 3D of high resolution since its application in 1958.According to exploration targets

seismic apparatus and acquisition methods

the history of 2D acquisition technology development can be divided into three stages:the single-fold stage(1958-1972)

the multifold stage(1973-1984) and the high resolution acquisition stage(after 1985);while the 3D acquisition technology development went through exploring(1966-1984)

developing(1985-1992)

large-scale application(1993-1999)

and high resolution acquisition(after 2000).Each technical progress results in a rapid growth of reserves in the oilfield and deeper understandings of the subsurface from simple structures

to complex fault block structures

and to subtle reservoirs.
