Western Sichuan foreland basin thickness, source-rich, multi-traps, good storage conditions, with the formation of medium-sized gas-forming conditions, exploration potential, is the Sichuan Basin to succeed within the important natural gas field exploration.

western Sichuan Basin sediment thickness, former land rich in hydrocarbon sources closed circle, and save more than good conditions to form a large and medium-sized gas field into possession of huge potential for exploration, Condition 4 Sichuan Basin, is an important natural gas field exploration s

The western Sichuan foreland basin deposit thickness is big, the hydrocarbon source is rich, traps many, preserves the condition to be good, has forms the large and middle scale natural gas fields to become the Tibet condition, the exploration potential is huge, is in the Sichuan basin the important

Sediment thickness in Western Sichuan foreland basin, rich source, traps, and good preservation conditions, conditions for formation of large and medium gas fields and huge exploration potential, is an important natural gas exploration in Sichuan basin in the replace field.

The basin deposition of land before the west of Sichuan is large in thickness, hydrocarbon source is abundant, enclose and close it more, it is good to keep the condition, possess and form becoming that hides the condition of the large and medium sized gas field, explore the potentiality enormously,
