Yumen Oilfield Laojunmiao Oil Production Plant cleverly uses graphene technology to solve the problem of waxing

As of January 3, after using graphene-coated wax-proof oil pipes in six wells, including F247H and duck k1-47 of Laojunmiao oil production plant in Yumen Oilfield, the average pump inspection cycle of oil wells has been extended by 105 days
.

Since 2022, in view of the problems of high well control risk, high cost of wax cleaning and frequent operation of mechanical wax cleaning and chemical wax cleaning, Laojunmiao Oil Production Plant has carefully analyzed and researched, and preliminarily selected 6 oil wells to carry out graphene tubing tests
.
Through one year of on-site follow-up evaluation, graphene double-thinned coated tubing technology effectively reduced the effects of wellbore corrosion, waxing and scaling, and the wellbore and surface pipeline transmission system operated smoothly, and the test was initially successful
.

The graphene coating anti-wax process is to cover the metal pipe wall with an organic polymer film to isolate the corrosive medium and prevent the corrosion
of the pipe string.
This process uses thermal spraying technology, has good adhesion, and uses the characteristics of the coating powder itself such as wear reduction, wear resistance, anti-corrosion and the powder can be moved to the sucker rod body to form a lubrication protective layer, etc.
, the downhole sucker rod and oil pipe are double-protected, thereby delaying the wear of the oil pipe and the oil pipe, and the coating surface has double thinness, which can effectively prevent waxing and scaling
of the oil pipe.
The use of anti-wax coated tubing can not only reduce the input cost of wax cleaning agent and hot washing, but also improve oil recovery, prolong the pump inspection cycle and the service life of
the tubing.

In the next step, Laojunmiao Oil Production Plant will continue to do a good job in the dynamic tracking and evaluation of graphene double-thinned coated oil pipes, summarize the test understanding, improve the well selection in the selection area, and vigorously promote the use of graphene coated wax-proof oil pipes
