Shanle O ilfie ld is the espec ially low pe rmeability oil
reservo ir of coal m easure interlay in Tuha o il reg ion, w ith
particu lar geo log ic condition and comp lica ted structure.
Because of depletion type o f explo itation in early per iod, the
reservo ir pressure has been keep ing on decline s ince putting
into production. The crude output has been declin ing
d istinctly and the producing energy is in dire need o f
supp lem enta ry. The paper starts w ith the questions o f coa l
m easure strata deve loped by w ater flood ing to m ainta in
producing energy. G rea t dea ls of experim ents and resea rch
have been ca rr ied through, and sufficien t demonstra tion to the feasib ility o f coal m easure form ation w aterflood ing has been
conduc ted from the po int o f techn ics. On the base o f abov e
w ork, the J2x form ation in Shanle Oilfie ld coa lm easure strata
has been carr ied out w aterflood ing practice. The o il w ells in
the sam e w ell group take on good effect, w hich offers them ost
d irect ev idence fo r the feasibility of w ater flood ing
developm ent in Shan le O ilfie ld and prov ides va luab le
experience and firsthand inform ation for cong ener coa l
m easure strata.
