Abstract:4-D seismic monitoring technique has been successfully applied in management of marine oilfields, but few cases showed the success of the method in land oilfields. On the basis of carefully analyzing the condition of reservoir and seismic condition, the paper pointed out the problems existed in 4-D seismic monitoring of continental thin and interbedded reservoir in China and presented some suggestions. The study considered that the petrophysical study and feasibility demonstration are the bases of implementing the 4-D seismic monitoring test of continental thin interbeddeds; improving repeatability of 4-D seismic data is the key; the study and application of prestack seismic attributes are major developed direction of 4-D seismic interpretation; multi-wave and multi-component seismic techniques are very important tools;current 4-D seismic monitoring tests of continental thin and interbedded reservoir should be first aimed at monitoring of heated heavy oils recovery, gas injection or CO2 injection recovery and water flood recovery for high-porous and unconsol-idated or poor-consolidated sand.
