Abstract During the implementation of CO2 fracturing for oil and gas development, the force transfer effect caused by the unsteady flow of high-pressure CO2 fluid can lead to forced vibration of the tubing and ensuing structural fatigue. In this study, a forced vibration analysis of tubing under CO2 fracturing conditions is carried out by taking into account the fluid-structure coupling and related interaction forces by means of the method of characteristics (MOC). The results show that for every 1 m3/min increase in pumping displacement, the fluid flow rate increases up to 3.67 m/s. The flow pressure in the… More >
