Abstract:

The main nature-gas reservoir is carbonate rock in Guizhou Chishui region. Whether the reservoir is good or not directly is influenced By the crack growth situation in the carberpate rock layer. Drilling detection shows that where's the crack develops, there"s the advantage segmentation of nature-gas res-ervoir. This article uses stcveture analysis method to systemati-cally research the structural feature of Chishui region, and confirm the relationship between structure and crack,-discuss the cracks increased period and times, character,distribution state and distribution realm in this region, which lightens the orienta-lion for further nature-gas exploration.

Key words: the structural feature, crack, nature-gas ex-ploration, Guizhou Chishui region
