摘要

The technology of 3D fault modeling based on well data and seismie data can improve the reliability and accuracy in basic geology study. Through adopting new technology and work process, the studying range of geology modeling can be broadened, and it is necessary to make it beeome a eomprehensive research project throughout the geological work of reservoir development from a specific research process. On the one hand, fauh modeling and basic geological study such as structure implementation and stratigraphic correlation can be fully combined through 3D fault modeling combined with well data and seismic data; on the other hand, basic geological research can be developed again with the higher technical requirements by the use of unique technical method of 3D geological modeling. Concrete steps of constructing fault model are given. Firstly, initial fault model can be established according to the seismic interpretation result; secondly, fault model can be corrected through the position of fault points in wells in 3D space; finally, fauh interpretation sehemes need to be modified because of the positions with fault point which can not be explained. In first member of Funing Formation, Zhuzhuang Oilfield of Qingtong Depression in Subei Basin, formal structure interpretation scheme and stratigraphic correlation are revised through the use of the technology, local structure high and fault throw are adjusted, and a new fauh is interpreted, all structures of different levels are implemented.
