    Abstract:

    The firefloodingdevelopment in Shuguang oilfield started in 2005, and has gone through pilot test, outstepexpansion test, scale test,andetc.At present, 105 well groups have been implemented, with the annual oil production reaching 24.1× 104t. With the increasing effectiveness of oil wells and the obvious increase of daily exhaust emission, the sand production of oil wells is increasingly serious. In 2016, the number of sand wells in blockDu 66 reached 240, which was 6.3 times higher than that before floodingconversion, seriously affecting the development effect of fire flooding. Through the correlation analysis of sand production and tail gas in firefloodingoil wells, and based on the key production nodes such as braising, releasing,collectingand lowering under different tail gas discharge conditions, a sand production well management method suitable for firefloodingdevelopment is gradually explored, which improves the oil well production time rate and ensures the development of fireflooding. This study can provide reference for sand control of oil wells developed by fire flooding.
