Shengli Binnan Operation Area Creates Effective Weapon for Coiled Tubing Technology

In order to seize the coiled tubing construction market and create a professional construction team, Shengli Oilfield Oil and Gas Downhole Operation Center Binnan Operation Area established a coiled tubing special class, strengthened staff skills training, carried out technical research, and gradually grew into a team.
"Light cavalry" who fights formidable and effective
.

Observe the first acquaintance

At the beginning of the establishment of the coiled tubing team, with the purpose of learning, assisted external units to carry out coiled tubing construction at Li 853 Station 2.
From basic operation steps to on-site scheduling and operation, the team members went from being unfamiliar and novel to knowing well, and from standing outside the cordon.
I watched from afar to enter the operation room to ask about the data, ask about the principles, move the house, assemble the tools, repair and maintain, and troubleshoot.
Every work is kept in mind
.

In order to ensure that the operators are familiar with and master the coiled tubing equipment as soon as possible, after the leaders of the operation area communicate with the manufacturer in advance, before the equipment is put into use, the coiled tubing team will transfer the core force to the manufacturer for training and learning, and the manufacturer’s engineering and technical personnel will conduct on-site operation and maintenance personnel.
The equipment basic knowledge theory explanation training mainly includes three aspects of coiled tubing mechanical structure, electrical and hydraulic operating principles.
Combined with the problems accumulated during the early stage of the coiled tubing construction process, everyone rushed to ask questions to eliminate doubts
.

At the same time, the center and the operation area formed a special investigation group for continuous oil, a group of 10 people, made a special trip to Jianghan Oilfield to "learn from experience" and learn about the system operation of coiled tubing construction, equipment and tools, site layout, construction operation and other aspects.
Through comprehensive and systematic learning, the team members have initially mastered the operating skills of coiled tubing equipment
.

Victory in the first battle

On December 6th last year, the delivery of coiled tubing equipment was completed, and all supporting equipment was delivered to the site of Li 853 No.
1 station
.

The manufacturer carefully guided and operated the operators from the side to operate the machine in turn.
The small operating room was crowded.
The 6 operators were able to independently complete the basic operations of starting and running the tubing.
The wellhead post was fully familiar with the procedures for disassembly, assembly and replacement of the tool string, and the equipment oil.
, Maintenance work is carried out in an orderly manner
.

Overcoming difficulties

Because coiled tubing equipment is a brand-new technology, everyone is crossing the river by feeling the stones, brainstorming, using their brains to solve a series of technical problems, and they are gradually handy
.

There are dozens of buttons, knobs and handles on the console, which is dazzling
.

　　In January this year, during construction in the Xianhe oil area, the pipe was being started at 3 am, the drum pipe system suddenly failed to work, and the automatic pipe arranging device failed.
Disassembly and inspection revealed that the sliding tongue body was seriously worn and debris blocked the track.
, Must be replaced immediately
.

　　South and North War

　　With the proficiency of business technology, the time for equipment relocation and installation has been shortened, and the construction efficiency has gradually improved, making "one well a day" gradually become a reality; for some sensitive formations or special processes, even oil equipment can not discharge pressure Continuous construction under pressure, plugging, sand flushing, and well killing were done in one go.

　　From January to June this year, coiled tubing equipment was transferred to various oil production plants in Shengli Oilfield, with a cumulative travel distance of more than 2500 kilometers.
