     The precision and accuracy of tectonic interpretation directly decide the success or failure of oilfield drilling. By comprehensively using the data of 3-D seismic, crosswell seismic, drilling and dynamic data at the same lime, the numerical simulation technology can greatly improve the accuracy of tectonic interpretation. Combined 3-D seismic data with drilling data, this paper realized the accurate inteqretation and position for the faults with the tault displacement Jess than 5 m within Wen 209 Block and carried on the detailed description fnr its interual small fold and fault block. Based on the acquisition of fault density, ueeurrenee, properlies, the author used the numerical sinmlation teclmology to predict the fault displacement, the occurrence of unknown small lhuh （including the strike, dip, Flipping angle of fault） and the distribution density of fault, realizing the fine structure interpretation of Wen 209 Blnck and improving the degree of small structure to be canied out, which greatly reduced the risk of the oilfiehl exploration and prnvided an important reference for deplnying the rolling development plan of oilfield.
