With the penetration o f exploration and exp lo itation,
every o ilfie ld a ll get into the h igh􀀁degree explo ra tion and
explo itation stag e. The clear and b igger structure reservo ir are
less and less bu t the propo rtions o f the stratig raph ic and
litho log ical traps o f the com plicated sub tle o il􀀁gas pools are
b igger and bigge r in oil and gas exp loration. The comp licated
fau lt􀀁block reservo ir is a im po rtant subtle o il and gas
reservo ir. But the o il reservo irs are com plicated and subtle in
structure, w hich can no t be d istingu ished w ith the usua lw ay s.
App lied rea lly for m any yea rs, the seism ic interpreta tion
techno logy is a be tterw ay to so lve the prob lem. In the paper,
tak ing the Dongy ing depression central antic lina l be lt as an
examp le, we have system a tica lly summ ed up the princ iples
and w ay s o f the se ism ic interpretation o f the seism ic forward
m ode ling and the se ism ic coherent analysis as w e ll as its
app lication to the com plica ted fau lt􀀁block o il rese rvo ir in the
exploration and exp lo itation. A better result w as ga ined.
