ABSTRACT
well
explored. In recent years the large scale of petroleum exploration
in the basin has led to the discovery of a series of oil and gas fields with an
approximate 1:1 ratio of oil to gas resource. This means that the natural gas resource is
very important for the hydrocarbon resource in the Tarim basin. In this basin most of the
discovered gases are condensate-associated gas and oil-associated gas. Research on
chemical components and isotope composition of carbon and hydrogen of natural gases from
the Tarim basin shows that all discovered gases in this basin are thermogenic. With
respect to source organic matter, there are two
types
of gases: (1) oil-type gas generated
from Sinian to lower Paleozoic marine source rocks with the sapropelic organic matter,
with -44.5 to -33.8o/oo of d13C1, -42.0
to -28.1o/oo of d13C2, -35.4 to -28.4o/oo
of d13C3, and heavier than -200o/oo of dD1 and (2) coal-type
gas generated from Mesozoic terrestrial source rocks with the humic organic matter, with
-40.5 to -33.1o/oo of d13C1, -29.7 to
-21.3o/oo of d13C2, -26.3 to -20.3o/oo of
d13C3, and lighter than -200o/oo of dD1.
