Abstract

Abstract: The phenomenon of wellhead growth caused by high temperature thermal expansion is widespread in major oil fields, which seriously threatens production safety. Based on the multistage heat transfer theory, the nonlinear heat transfer process and thermal expansion phenomenon of multistage casing-cement sheath-formation are simulated by finite element method, and a new wellhead lift calculation method is proposed. Taking Well X1 of a block in Xinjiang Oilfield as an example, the risk assessment and analysis of various string wellhead under different working conditions are carried out. It is found that under the limit production conditions, although the casing at all levels has a large lifting force at the wellhead due to the cementing effect of the casing annulus, the wellhead uplift phenomenon does not occur. However, when the casing cement sheath is damaged to a certain extent, the overall wellhead lift occurs, and the overall wellhead lift decreases from 3 cm to 2 cm under the action of the pressure and weight of the wellhead device. The results show that this method can quantitatively evaluate the wellhead safety in the actual production process, and has certain guiding significance for the actual field wellhead lifting calculation and risk evaluation.

Key words: finite element method, multistage heat transfer, wellhead growth displacement, cement sheath sealing effect, wellhead safety
