摘要

 

    

The Sulige is situated in the northwest of the Ordos Basin with an exploration area of 40 000 km².  PetroChina Changqing Oilfield Company has made deep investigation into integrated geological research and has developed many exploration techniques. As a result, effective gas reservoir distribution and gas enrichment rules in the Sulige gas field are clarified, and advanced and practical exploration techniques are formed including the seismic forecast on effective gas reservoirs, the logging evaluation on the complicated gas pay zones, the stimulation measures of dense sandstone gas reservoirs, and so on. Through overall exploration in the Sulige area, a first mono-block gas field with the reserves of more than 10 trillion cubic meters has been explored, where the original gas in place is up to 2. 85 trillion cubic meters, and the southern Sulige part has become a new gas resource turn-over zone.
