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