Abstract: Ever since super heavy oil producers in Shu1 area of Liaohe oilfield entere latter cycles of steam huff and puff, there exist some problems that steam huff and puff effect gets worse, oil production is decreasing, and its costs producing per ton are increasing. However, after analyzing the main factors carefully that influence the effect of developing in latter cycles well, many kinds of technical methods such as combination steamhuff and puff, intermittent steam huff and puff, multiform steam huff and puff are given and applied, thus, single steam huff and puff module are broken through, the use of heat efficiency is raised, and the effectiveness of steam huff and puff in latter cycles is improved. These measures provide a reference to develop super heavy oil reservoirs and heavy oil reservoisr in other areas.

Key words: super heavy oil, integrated steam huff and puff, intermittent steam huff and puff, multiform steam huff and puff, steam stimulation in latter cycles
