PRESENT SITUATION OF NATURAL GAS GATHERING IN CHANGQING GAS FIELD

In view of the development and construction characteristics of Changqing gas field with low permeability,low abundance and minor production,a series of new techniques adopted in Changqing gas field surface construction,i.e.high pressure gas gathering,centralized injection of alcohol,multiwell heating,gas purification and automatic control,etc.,are briefly introduced.Through practice,it is proved that these techniques are suitable to the conditions in Changqing gas field and they can make the readers to understand roughly the gas gathering situation in the field,being available for reference in developing low permeability,low abundance and low production gas field at high efficiency.
