Providing reliable chemical protection against corrosion and asphaltene-resin-paraffin deposits of metal equipment for oil production on offshore platforms is achieved by applying polyfunctional corrosion inhibitors. An adjustable dosing supply of polyfunctional corrosion inhibitors is performed to a predetermined depths, depending on the technical and technological peculiarities of the oil well production, located on oil platform and in the produced fluid conduit at the wellhead.
The benefits of multifunctional corrosion inhibitors, which are used to protect against corrosion and asphaltene-resin-paraffin deposits of metal equipment for oil production on offshore platforms, in front of analogues, it is a complex action. That is, one reagent provides, and very effectively, functions of several reagents, namely a corrosion inhibitor for protection of metallic equipment for oil production offshore against corrosion; reagent for inhibiting oil asphaltene-resin-paraffin deposits of metal equipment for oil production on the offshore platforms and the washing off asphaltene-resin-paraffin deposits from its wall; reagent for the removal of minerals, clay and sand deposits and corrosion products. The application of multifunctional corrosion inhibitors for protection against corrosion and asphaltene-resin-paraffin deposits of metal equipment for oil offshore is technologically simple. It does not require the creation and installation of the special optional equipment at offshore platform that is technologically and economically profitable.
