Study on Influence of temperature on cementing in deep shale oil and gas exploitation

Abstract In this paper, the mechanical model of sheath has been established according to engineering practice and analysed in two aspects: temperature acts alone pressure act together. The results demonstrate that it is unnecessary worry negative influence individual action. Temperature can cause many adverse characteristics on cementing: thermal stress material properties. coefficient ? coming from effective conduction heat, prove condition cement ring terms stress, its size positively correlated with difference. Mechanical properties usually will be changed at high tempature, measured by later experiments, which discuss role further.
