Abstract:

Gas pool-forming mechanism differs greatly from oil pool-forming mechanism.Separate reservation,superpressure migration,reservoir formed pool and multi grade supply is the popular gas pool-forming model.Transtensional fracture developed area is favourable for the formation of gas reservoirs.To explore gas resources,one should adopt multi lateral horizontal well in drilling-planning and unbalance drilling in operation.

Key words: natural gas, pool-forming moedl, reservoir, horizental well
