In th is pape r, a new m ethod of support vecto r m ach ine
( SVM ) is pu t forwa rd based on the sta tistica l ana ly sis of the
resu lt of m assive im plem ented profile con tro l and fo r
pred icting the result o f pro file contro.l It uses the support
v ictor m ach ine theo ry to represent nonlinea r relationship
betw een the resu lt o f profile contro l and its factors. Th ism ode l
stud ies the case h istor ies. It can pred ict the fast resu lt of
profile contro l fo r s im ila r reservo ir conditions. Severa l support
v ictor m ach ine models were established for o il production
increm ent, w ater production decrease, climb of wa ter cut and
so on. The result ind ica ted tha t the m odels g ive the accurate
pred ictions fo r the nov el conditions and the m ethod has the
w idespread application prospect.
