| Abstract: | A superdeep Middle Proterozoic Wumishan carbonate buried hill oil and gas reservoir,which is deep buried within Baxian Sag,Jizhong Depression,was discovered in Well ND-1 in January,2011.The drilled depth reached to 6027m at the bottom of the Niudong-1 buried-hill reservoir where no oil/water interface was met and the temperature is at 201℃(about 394℉) at the well bottom.The acid-fracturing well test gave the high output rate of 642.9 m3 oil and 563×103m3 natural gas per day.It is the oil and gas reservoir with the greatest well depth,the highest output and the highest well-bottom temperature that has discovered up to now in Bohaiwan Basin,even in the eastern part of China.The exploration history for more than 30 years that has undergone from failure,through putting-aside and reviving to success is reviewed.Three key technology and their important actions playing in exploration are described.The first technology is the "high-precision gravimetric and magnetic survey" that supplied important clue for the discovery of the superdeep buried hill,the second one is the "secondary 3-D seismic survey" that achieved the accurate orientation for the buried hill trap,and the third one is the "high-T-resisting,deepening and voluminous acid-fracturing" that supplied the effective technology ensure for well testing to obtain high oil and gas output in the superdeep and superhigh T reservoir. |
