Say Goodbye To Hard Work And Dirty Workover With Robots

In Xinjiang Oilfield Company's Baili Oilfield, there are also robots for workover operations, which makes the workover workers very pleased, because workover operations can say goodbye to the history of "hard work and dirty".

In major oil fields, oil extraction machines can be seen everywhere. This kind of equipment that tirelessly extracts oil from the ground is often called "kowtow machine". The mechanical equipment of the "kowtow machine" is connected to the oil pipes and sucker rods in the wellbore. They are the key equipment for oil production. In the continuous wind and sun and repeated work day after day, it is inevitable that they will be worn out and even malfunction. After years of continuous operation in oil wells, wellbore blockage, damage, or severe wax formation will occur, resulting in reduced or stopped production of oil wells. At this time, the workover team needs to assume the responsibility of "oilfield doctors".

Once there is a problem with the oil extraction machine, workover workers are required to go to the well to carry out workover operations. "Before there was no 'workover robot', we had to stand at the wellhead to pull out the tubing and sucker rods, and replace them with new equipment after shackles, cleaning, and flaw detection. It also smells like oil." said Talehati Dawu, captain of the third minor repair team of the Baikouquan Project Department of Karamay Jianye Energy Co., Ltd.

Karamay Jianye Energy Co., Ltd. is an oilfield technical service company with more than 20 years of experience in oil well overhaul and oilfield stimulation and injection services. Since 2014, it has started research and development of automatic workover equipment.

In 2020, Karamay Jianye Energy Co., Ltd. Technology Research and Development Department will independently become Karamay Zhongcheng Petroleum Equipment Research Institute Co., Ltd., and Karamay Jianye Energy Co., Ltd. will form a research and development application consortium. The former is responsible for R&D and improvement, and the latter Responsible for app feedback. The two parties have created a complete closed loop of automated workover equipment from R&D and production, field application to feedback improvement, laying a solid foundation for the rapid development of automated workover equipment manufacturing. In December of that year, the third-generation integrated minor repair and environmental protection operation system was successfully developed, and the third under pressure minor repair team of CCRE Energy Co., Ltd. conducted a preliminary trial at Baikouquan Oil Production Plant.

In 2021, the workover team where Talahati works ushered in a new generation of intelligent workover operation system, which is a set of equipment that uses technology to change the traditional operation method, from grabbing oil pipes, sucker rods to make-up of pipe rods The shackles and shackles are all intelligent, and the wellhead of the oil well does not even need people during operation. The workover workers say that this is a "workover robot".

Talahati said that with the "workover robot", the workover workers don't need to be busy at the wellhead, but just sit in the driller's room and operate the buttons and levers to complete the lifting, lowering, make-up, The construction safety of shackles, oil rod flaw detection and other work has been guaranteed to a large extent, and the oil stains on the tooling have disappeared.

With the "workover robot", the labor intensity of the workover team has been greatly reduced, and the number of team members has also been reduced from the original 8 to 4.

In 2022, Karamay Jianye Energy Co., Ltd. Baikouquan Project Department's third under pressure minor repair team will work over 22 wells, all of which will use "workover robots". This winter, the engineers and technicians of Karamay Zhongcheng Petroleum Equipment Research Institute Co., Ltd. are still further improving the function of the "workover robot". Talehati believes that the "workover robot" will be more intelligent.

Gu Tao, deputy general manager of Karamay Zhongcheng Petroleum Equipment Research Institute Co., Ltd., said: "The company has invested a total of 30 million yuan in the research and development of an intelligent workover operation system. It will be listed as a major special science and technology plan project of Karamay City in 2022. At present, the automatic operation of multiple links such as grabbing, handling, lifting, making and unloading, and flexible righting of the oil pipe has been realized, and the traditional manual work has been realized. substitute."
