Abstract: The sand control problems of multiple cyclic steam stimulation (CSS) mainly include destruction of the sand barrier, failure, and short validity period of sand control. Uncompaction of packing layer and loose arrangement of filling sand may cause sand migration or even collapse in the formation, which results in plugging and reducing seepage capacity in the near-wellbore zones. Some bottleneck problems limit the development, such as short effective period of sand control, rapid production decline, casing deformation, and casing damage. Sand plugging or sand burial at the bottom hole mainly causes these problems. To solve the above problems, fibre consolidation with high-temperature resistance is developed. Additionally, the layered sand control and steam injection string are used. Finally, the technology of balanced dense filling and sand control is developed, which can effectively increase the strength of the sand barrier, extend the validity period, and realise high-efficiency development of the wells after multiple CSS.
