The Enriched Regularity And Controlling Factors Of The Shallow Gas In Changyuan Xingshugang Area Of Daqing

The shallow gas formed under a relatively shallow depth, and is a form of the gas reservoir occurred in the northern Changyuan of Daqing. This study focuses on the determination of the distribution and identification of the shallow gas in the Shaling formation, and the second, third and fourth sections of the Nenjiang formation from the bottom to top. The control factors and enriched regularity of the Xingbei shallow gas was determined, and a set of suitable identification technology for the Xingbei shallow gas was made. The above study can provide a good way for the drilling well control protective measures and detailed and reliable policy basis for exploration and management to ensure safety in production.
