摘要
传统试井施工作业需要人工举升测试仪器,攀爬到防喷管顶部,将仪器送入高3.5 m的防喷管内,存在工人劳动强度大、效率低、安全系数低等问题。研制的自动举升试井防喷装置,以便携无线液压泵站为动力源,驱动液压油缸,在地面完成将仪器装入防喷装置的所有安装工作;举升过程中,液压油缸将防喷管顶起,防喷管自动对接完成安装;施工结束后,按反安装顺序拆卸防喷装置。为了施工安全,对防喷管强度、立柱尺寸进行了适应性验证,对采油树受力情况进行了分析。该装置在大庆油田完成生产试井12万多层,应用效果显著。
The traditional well test operation requires workers to climb to the top of the blowout preventer and send the instrument into the blowout preventer with a height of 3.5 m,which has the problems of high labor intensity,low efficiency and low safety factor.The developed automatic lifting well test blowout preventer takes the portable wireless hydraulic pump station as the power source driving the hydraulic cylinder and completing all the installation work of installing the instrument into the blowout preventer on the ground.During the lifting process,the hydraulic cylinder jacks up the blowout preventer,and the blowout preventer is automatically butted to complete the installation;when the construction is completed,the blowout preventer is disassembled according to the reverse installation sequence.In order to ensure the safety of construction,the adaptability verification of lubricator strength and column size was conducted,and the mechanical force of Christmas tree was analyzed.The device has been used in 120000 wells in Daqing Oilfield,and the application effect is remarkable.
