Abstract:

There are many technical problems in the underground gas storage reconstruction,among which sealing property
of cap rock,reservoir characteristic and the selection of reinjection formation are key issues. Based on logging information,a
specific logging analysis is carried out on some crucial issues,such as cap rock sealing ability,reservoir quality and distribution
and sewage rejection formation selection in the process of reconstructing Junggar Basin H underground gas storage. We find
out that the Hunderground gas storage has thick cap rock,poor physical property,wide distribution and sound sealing ability.
The E1-2z2 reservoir has features such as wide distribution,great stablility,large thickness,good physical property and good
connectivity,which can meet the requirement of constructing underground gas storage for the reservoir permeability space.
Through water layer well logging and evaluation of Dushanzi Formation,we believe Anjihai Formation and Shawan Formation,
Shawan Formation are the most reasonable sewage reinjection layers.

Key words: underground gas storage reconstruction, logging evaluation, caprock, reservoir quality, sewage reinjection
