Abstract

Purpose. Determination of the chemical composition of a sediment sample on the casing and parts of a well-bore electric pump unit, which has been operated for several years under conditions of the Kursk-Belgorod anomaly; identifying the possible causes of unit failure and developing recommendations for equipment operation.

Methods. The program for studying a sediment sample has been developed, including determination of the mass fraction of organic substances (the organic component of the sediment) by the weight method, mass fraction of iron by the spectrophotocolorimetric method on an SF-2000 spectrophotometer, the mass fraction of manganese by the titrimetric method, content of zinc, cadmium, lead and copper by stripping voltammetry on the voltammetric analyzer AVA-3.

Findings. The content of organic substances in the sediment (50.1 %), mass fractions of iron (5.6 %), manganese (6.6 %), lead (3.4 %), zinc (0.017 %), copper (0.005 %) was established, no cadmium was detected. The probable reasons for the accumulation of sediment on the surface of a well-bore electric pump unit are formulated. Based on the results of the study, the recommendations were proposed for the operation of submersible electric pump units, including above all the need to take and analyze water samples from the well before installing the equipment.

Application field of research. Based on the results obtained from studying a sample of sediment from the body of a well-bore electric pump unit, the recommendations for the operation of the equipment were formulated.
