The A-5 well area Y2Ⅱdn of Dongfang A Gas Field in the central diapir zone of Yinggehai Basin is a gas reservoir controlled by structure and lithology,and the A-5 well is drilled into a thin gas layer within the well area.Through the analysis and research of new drilling,logging,seismic and logging data in the field,it is clear that the main block of the study area has large reservoir thickness,high confidence of gas bearing sand body,good reservoir physical property,industrial productivity by analogy analysis,The level of geological reserves of Y2Ⅱ dn in A-5 well area has been upgraded from control to proved.
