Abstract: This paper presented the sand control mechanism of laser slotted screen liner and the way to con-firm slotted screen width and length. The compatibility of slotted screen liner and formation packed sand was studied. The technology of laser slotted screen liner fracturing gravel packing sand control is economical, practical and with high reutilization rate, by which the problems of wire-wrapped screen were settled such as complex structure, hard salvage etc. At the same time, after adopting the technology of fracturing in wells with transnormal high viscidity of Liaohe oilfield product sand, the production grown stably and continually.
