The finite element model of four packer rubber materials was established by using ABAQUS and FE-SAFE software. initial sealing load (the is the pressure) 11.85 MPa, working 58.15 MPa. evaluation coefficient, maximum contact stress, fatigue life value material rubbers were considered when considering temperature changes unit nodes. results show that structural parameters are same, coefficient increases with increase temperature. When reaches 125 ℃, seal HNBR largest, EPDM smallest. Similarly,...
Purpose The purpose of this paper is based on the response surface method, authors determined conditions for achieving optimum rubber-sealing performance by using maximum contact stress as value. Design/methodology/approach A two-dimensional model a compression packer rubber was established finite-element analysis software. Under single axial load 53.85 MPa, four factors end-face inclination angle, subthickness, height and friction coefficient were analyzed. Findings Results show that...
The hot exhaust gas generated by a downhole combustion heater directly heats the formation, which can avoid heat loss caused injection of high-temperature fluid on ground. However, if temperature is too high, it may lead to carbonization organic matter in not conducive oil production. This paper proposes use low-temperature catalytic mixture methane and air produce suitable temperature. simulation studies influence different parameters characteristics high-pressure conditions. results show...
Tunneling in sandy dolomite strata often faces hazards such as collapse, water inrush, and water–sand seriously threatening the safety of tunnel construction. There are currently limited studies on mechanical behaviors tunnels. In view this, an analytical solution for tunneling is derived this study, then parametric analysis performed to analyze response rock mass The results demonstrate five sidewall stress scenarios according different lateral pressure coefficients ( λ ). Varying values...
With the development of human science and technology improvement industrial level, waste gas emitted from production seriously pollutes environment causes energy. In order to rationalize use low calorific value gas, heat transfer performance catalytic combustion heater for system energy efficiency process are analyzed. this paper, analyzed exhaust temperature, methane conversion rate heaters under variation single factorial variables. The results show that larger values pore radius,...
