Xie Peiyong (Exploration and Development Research Institute of Nanhai West Corporation,CNOOC).  
DF1—1 gas field is located in the north of the mud diapir structure belt in Yinggehai Basin,being a successive anticlinal structure formed by mud diapiric activity,i.e.an integral shallow giant gas field.The petrophysical property of the reservoir in the field is good with a high gas well productivity.It is an offshore beach and bar deposition formed by the action of the wave and ocean current in bathyal marine zone.The properties of the natural gas in Gas Formation Ⅱ at the west area of the prominent part of the field are low carbon dioxide content,high nitrogen content and high methane content.It is a dry gas reservoir and its driving type is mainly the elastic weak edge water drive.In the process of exploration evaluation of the field,a series of new techniques and methods were adopted,such as high resolution seismic survey,relative wave impedence,low resistance gas formation identification,reservoir inclusion analysis,mercury injection test and log analysis,etc.,so as to realize the demand of more extensive offshore exploration by drilling less wells and to achieve the purpose of raising working efficiency and economic benefit.
