修井井口机械化自动化装置的研究进展

Research of Progress of Mechanized and Automated Workover Wellhead Equipments

对近20年来国内外修井井口作业设备的机械化、自动化水平进行了分析,介绍了应用现状及局限性。根据修井井口作业工序和现场实际情况,总结出实现井口操作机械化的关键技术。结合我国修井作业的现状认为,应充分利用现有修井设备,借鉴并引用钻井井口作业装置的机械化技术,设计制造出能与不压井作业装置配套使用、方便快捷地拆装和移运及易于操作控制的修井井口作业机械化、自动化装置,以提高作业效率和安全性,减轻劳动强度,达到环保要求。

The mechanization and automation status of domestic and international workover wellhead operation equipments are analyzed, and the application status and limitation of them are introduced. Based on workover wellhead operation process and actual situation, the key technologies to realize the mechanization of wellhead operations are summarized. According to the present situation of workover services in our country, it is considered that the workover wellhead operation mechanized and automated equipments should be developed on the basis of the full use of the existing workover equipment and reference from the mechanized technology of drilling wellhead operations. Also, the equipments should support the use of snubbing unit, easy shifting and transporting, convenient assembly and disassembly, and simple control so that higher operational efficiency and safety, lower labor intensity, and environmental requirements can be obtained.
