Abstract:

Lithogeny trap with complex relationship between gas and water is developed widely in the west area of Amu-
Darya Basin. Some lithogeny traps are characterized by very complex water-gas relationship with different reservoir for each
single well. The article emphasizes the concept of lithogeny trap and analyzes the exploration methods on lithogeny trap by
learning the causes of lithogeny traps. Based on exploration practice in west area of Amu-Darya Basin，and taking advantage
of paleostructure recovering and complex carbonate reservoir prediction technology，we researched the characters of lithogeny
trap which conclude the recognition of lithogeny trap. Later stage lithogeny function and new tectonic movement are both
key factors in the formation of lithogeny traps with complex water-gas relationship，inclined gas-water contact，and different
reservoir for each single well. The exploration practices in west area of Amu-Darya Basin lead to following conclusions：the
palaeostructure learning，which is followed by the research on lithogeny and reservoir development on the basis of cores and
reservoir prediction is effective method in lithogeny trap exploration.
