The ma in produc tive zone o f Keerq in O ilfie ld be longs to
the fractured reservo ir w ith m iddle porosity and ve ry low
perm eab ility. As it is in fluenced by the natura l and m anm
ade frac tures, thew ate rflooding is pushed into the fracture.
The fractures are qu ickly wa terfooded and the o il recovey
deg ree is decreased. In o rder to change the s ituation, w e
have m ade m any exper im ents and developed the vo lum e
expanation gra in and the weak ge l pro file control techn ique.
W e hav e made the fie ld test of fracture sem iplugg ing in the
injection w e ll o f B lock Bao 14 of Keerq in o ilfie ld. The
produced crude o il is increased and producing w ater cut is
decreased.
