Предотвращение осложнений при использовании несовместимых вод в системе поддержания пластового давления

Abstract

A pressing task in the operation of a reservoir pressure maintenance system is the prediction and monitoring of the state of the internal surface of pipelines and the total amount of sediment. The article examines the mechanism of formation of salts of carbonate and sulphate groups in the process of mixing reservoir and artesian waters, which are incompatible, when used in the system for maintaining reservoir pressure. The mechanism of formation of iron compounds when mixing waters with different pH values is considered. The effect of bacteriological contamination of the production media on the increase in the amount of iron sulfides in the production media, as well as the development of equipment biocorrosion is shown. The features of biodegradation of the field pipeline system under conditions of low reservoir temperatures are considered. The most promising methods of dealing with scaling and biocorrosion under conditions of low temperatures of field fluids are noted.
