Key Technologies for Automation Control of Ultra High Voltage Heavy Wellhead Equipment
With the deepening of domestic oil exploration and development,the existing wellhead equipment with rated pressure of 140MPa can no longer meet the requirements of use,and it is necessary for China to develop ultra-high pressure major wellhead equipment with rated pressure of more than 175MPa to meet the needs of oil and gas development in deep Wells with ultra-high pressure and high temperature Wells.The ultra-high pressure major wellhead equipment with rated pressure above 175MPa has high pressure resistance and can be opened and closed manually,but considering the safety of operators and in order to improve work efficiency and reduce work intensity,the paper developed automatic control valve and electric drive valve to achieve remote automatic control.
