Abstract: The cold production technology of heavy oil is based on both earthworm-shapedchannels which occur after a great lot of sand is produced and steady foamy oil, by which the oil produc-tion can be remarkably enhanced. This technology has found satisfactory application in Henan Oilfield and also successfully used in middle-depth, very thin heavy oil reservoirs. The oil
rate of first pilot well was8 times that of the common wells, 4 times that of the steam soaking wells, whilethe production cost was 47% less that of the steam soaking wells. This technology was also successfully applied to low cycle steam soaking wells in heavy oil reservoir, which improved the oil rate by 1-3 times.

Key words: heavy oil production, sand production, steam soaking
