Fo rm ing m echanism and distributing rules o f the gas
accumu lation w ith h igh- pressure and low - pe rmeability are
d ifferen t from the comm on hydro ca rbon reservo irs. Because of
the spec ia l g eo log ica l character istics, the appraising resu lt is
not exactly sam ew ith the o il testing. By ana ly zing the reasons
o f the abnorm a l h igh - pressure and the cha racter istics of
deep leve l osm ose configuration, and assoc ia ting w ith the
d istr ibu tion and geo log ica l mud logg ing character istics o f the
h igh- pressure and low - permeability gas accumu lation in
Dongpu Depression, th is paper researched how to d istingu ish
the new mud logg ing eva luation m ethod, such as gas
chrom atographic technique、light ends technique o f the h ighpressure
and low- perm eab ility gas accumu lation. The paper
prov ides am e thod to appra ise the h igh- pressure and low -
perm eab ility gas accumu la tion co rrectly by using mud logg ing
eva luation.
