Use of protector to prevent corrosive wear of wellhead process piping

Abstract

Introduction. In conditions of high corrosive aggressiveness of the produced products the actual task is to search for new solutions for protection of downhole equipment. This paper analyses existing solutions for corrosion control and proposes the use of an untypical corrosion protector to protect the wellhead tie-in from premature wear.

Aim. Development of a new technical solution to protect wellhead piping from corrosive wear and tear Materials and methods. Well performance data as well as data on geometric parameters of the corrosion protector were used as input data. The macro package in the VBA programming language was used to perform calculations.

Results. A new method of protection of wellhead piping from corrosion was proposed, a non-typical corrosion protector was developed, universal tool for selection of corrosion protector sizes was created, and the effectiveness of the proposed solution was proved by calculations

Conclusion. As a result of the analysis, calculations and pilot tests, it was determined that the corrosion protector is an effective method of corrosion control, as well as does not affect the mode of operation of the well.
