Frequent breaks due to corrosion in pipelines

Collection and analysis of field information on the intensity of corrosion on surface oilfield equipment. Collection of information on process facilities based on inlet and outlet pressure, pH temperature. Physico-chemical properties of oil-produced water and gases dissolved in them. Determination of technological lines of components and assemblies that are most susceptible to corrosion, the consequences of which have the maximum negative effect on the processes of the oil field Research in the field of chemical reagents used to prevent corrosion and combat corrosion, analysis of their effectiveness, as well as analysis of technology and dosage regimens of chemical reagents Analysis of possible conflicts of chemical reagents with residual reagents from other technological cycles with a decrease in the effectiveness of corrosion control Selection of process objects – for corrosion protection and monitoring: wastewater collector with NFS UPSV, TsPPN entrance of each BKNS collector of the Albsenomanian waters Sampling of produced water and study of the physico-chemical properties and composition of oil and produced waters to conduct a preliminary assessment of the corrosive activity of the liquid (level of CO2, O2, pH, H2S and six-component composition of water, EHF. No more than 20 samples) wastewater collector with NFS UPSV, TsPPN collector of Albsenomansky waters Selection and cutting of pipes with corrosion damage and deposits to determine the type of corrosion damage and the type of deposit in the laboratory. Laboratory research: IR input control; bench laboratory tests on simulant water (with the physical and chemical properties of produced water) with the addition of acid gases to determine the overall background corrosion rate. study of the effective action and optimal concentration of IR in laboratory conditions; determination of residual IR content (no more than 20 samples after the start of IR injection); identification of the causes of corrosion, pipe samples taken from the site: full chemical analysis (spectral), chemical analysis of corrosion products; complex of metallographic tests; issuance of a test report. Installation of corrosion control units (CCU) at pipeline control points (inset of branch pipe with valve) on the water collector line UPSV, TsPPN, inlet of each BKNS, Albsenomansky waters collector. Installation of witness samples (OS) and measurement of the background corrosion rate using the gravimetric method on the CC at process facilities. Exposure time for witness samples is 20 -30 days. Monthly installation and removal of witness samples and measurement of corrosion rate at the UCC after injection of a corrosion inhibitor at process facilities (coupon exposure time 20-30 days). Development of a comprehensive solution to combat pipeline corrosion Processing the results, preparing a report on the results of the work performed, issuing conclusions. Development of a scientific report Requirements for organization and implementation. - To collect information and study operational documentation, the Contractor carries out a visit to the facility location. - The Contractor provides the entire scope of technical inspection services using its own resources, instruments, tools, equipment and at its own expense, including accommodation and meals. - Availability of an accredited or certified laboratory by the Contractor (own or on a lease basis, or a contract for the provision of services). Supporting documents are an accreditation certificate or a Measurement State Assessment Certificate or a service agreement. - If necessary, the Customer provides the Contractor with access to production units and allows the Contractor to collect the necessary technical data in accordance with the requirements.
