The techno logy o f im prov ing rock phys ica l properties is
an effective m e thod for developm ent o f the low perm eab ility
o ilfie ld, and the techno logy o f􀀁 exp loding in fracture􀀁 can
g reatly enhance o il recovery fo r the low pe rmeability o ilfie ld,
so it is necessary to do som e farther research on the
techno logy of im prov ing ro ck phy sica l properties. Th is paper
concludes the basic param eters o f descr ib ing the fractures and
the re lation betw een the param eters and perm eab ility of
fractures. Draw ing lessons from prob ing natural fractures and
fractures o f hydrau lic fracturing, this thesis tallies up four
m a in m ethods o f ana lyzing fractu res from the re ferences: core
fractures ana lys is, se ism ic analysis, w ell logg ing ana lysis and
w e ll testing analysis. Comb ining w ith the actua l situation of
producing frac tures from exp lod ing in fractures, it also
analyzes the abov e m ethods, and sieves to choose app licab le
m ethods to evalua te the resu lt o f exp loding in fractures.
