The solution on corrosion problem of downhole pumping equipment marginal wells

For the first time in the fields of producing wells conducted pilot tests of encapsulated corrosion inhibitor, as a way to improve the effectiveness of protection against corrosion and increase the operating time of equipment at the expense of long-removal agent after treatment.
Materials and methods
Field trial of encapsulated corrosion inhibitor.
Results
The technology of application of encapsulated corrosion inhibitor to stack of marginal wells was presented.
Сonclusions
1. The use of the encapsulated corrosion inhibitor provides constant presence of a reagent in the produced fluid at the required level of protection to ensure a degree of 90%.
2. The use of encapsulated corrosion inhibitor to stack of marginal wells can increase operating time up to 2 times.
