Efficiency Improvement of the First Set of Automatic Workover Equipment in Dagang Oilfield

As of May 8, the first set of automatic workover equipment in Dagang Oilfield has been running safely and smoothly for 20 months, with 92 workover and completion Wells and 111,000 pipe strings, reducing the labor intensity of employees, reducing safety risks, and improving the workover efficiency.

In the traditional mode, there are many workover processes, the work intensity of employees is high, and the safety risk is high. In order to reduce the labor intensity of employees and improve the efficiency of workover, Dagang Oilfield Underground Operation Company established a project to carry out the project of "automatic workover operation device and supporting technology", set up an expert team, conducted in-depth on-site research needs, and refined the functional parameters of the device. After research, the first set of automatic workover equipment in Dagang Oilfield was successfully tested in September 2022. Workover staff use the operating rod and remote control to direct the device to lower the pipe rod into (lift out) the wellbore, realizing unmanned operation at the wellhead, reducing labor intensity and safety risks by more than 80% compared with the traditional mode, and increasing production time by more than 20%.

Dagang Oilfield downhole operation company insists on testing while improving, verifying and upgrading, expert team stationed in the well to improve the controllability and field adaptability of the device, and form a new automatic workover model suitable for the actual production of the oilfield. Up to now, Dagang Oilfield has promoted the use of 10 sets of automation devices for workover machines, 61 sets of mechanized devices for drilling machines, and completed more than 2,400 Wells.
