There are abundant geothermal resources underlying in Xiong’an New Area， and the Wumishan carbonate geothermal reservoir of Jixian System has been the prior target geothermal reservoir so far. Highly developed fracture network of Wumishan carbonate geothermal reservoir in Xiong’an New Area leads to severe lost circulation of drilling fluid during geothermal drilling， and thus geothermal reservoir damage， which causes the decline of geothermal well productivity. In order to achieve the shielding of fractures during geothermal drilling in conjunction with reservoir protection， which aims at maximum productivity improvement， it is proposed that the application of shape memory polymer with shape memory effect sensitive to temperature could be feasible for temporary shielding during drilling in Wumishan fractured carbonate geothermal reservoir in Xiong’an New Area. Temperature sensitive shape memory polymer is capable of effectively dealing with the lost circulation problem induced by highly fractured target geothermal reservoir， while guarantees the maximum geothermal reservoir protection by thoroughly exiting from the fractures， and its application is a promising temporary shielding technology for fractured carbonate geothermal reservoir， which provides a novel technological method for efficient drilling and geothermal reservoir protection in Xiong’an New Area.
