Metrological support of equipment for geophysical research

Abstract

The article discusses the problems associated with metrological support of equipment for geophysical research, issues of ensuring the uniformity of well measurements, the creation of Russian standards for calibrating well equipment when determining the porosity coefficients and oil, gas, water saturation, determining the parameters of defects during well cementing and technical condition of casing strings and the water-oil-gas flow. The problems of creating full-fledged methods for measuring the parameters of oil and gas fields with conventional and hard-to-recover reserves have been investigated. The key directions of development of the Russian metrological support of geophysical well measurements were determined. The tasks that need to be solved to create metrological support for geophysical well logging as an industry that meet international standards are indicated. The expediency of creating a Russian Geophysical Center for Metrology and Certification, the need to develop a new and update the existing regulatory framework, which will allow Russian geophysics to reach the level of world leaders in the field of geophysical research, are substantiated.

Control of pollutants in the atmospheric air on the example of an automated monitoring system in St. Petersburg

“…Based on the foregoing, the determination of VOC concentrations in the atmospheric air, especially in residential areas, is the most important task at present. In order to assess the quality of the air environment, observation systems have been organized [4,7,31] using selective, sensitive, stable, accurate and reliable methods and instruments [32][33][34]. Nevertheless, carrying out a full-fledged instrumental monitoring is associated with a number of difficulties, for example, the impossibility of promptly obtaining data from remote areas, which is especially important for the Russian Federation, as well as the selection of representative samples of VOCs.…”

Metrological supply of water pumping in oil and gas fields

“…With this method, there are four to five plugging wells per bottomhole. Under favorable geological conditions this method gave good results (Bavli field D-G layer, Tuimazin field D-G layer, Khodjaabad VIIIhorizon of Fergana valley) [5][6][7][8][9].…”

“…The heap-elastic style of operation. In these cases, the viscosity of the oil in the layer is also low, and the reservoir properties of the reservoir are not uniform [4][5][6][7]. In this condition, most of the water that has been pumped up to the boundary rushes toward it and displaces most of the oil that can be recovered from it to the bottom of the wells.…”

Possibilities for creating Russian high-tech bottomhole assembly

“…• Развитие каротажа в процессе бурения, направленное на: повышение точности LWD ±10 до 2 % за счет создания сети метрологических полигонов, распределенных по федеральным округам РФ, соответствующих мировому уровню, и разработки (актуализации, обновление существующих) методик интерпретации данных ГИС [2]; увеличение глубины зондирования горных пород более 12 м, повышение степени автоматизации и экологической безопасности [14]; развитие методического и программно-интерпретационного метрологического обеспечения, соответствующего его мировому уровню [17]; разработку и внедрение отечественных систем LWD с азимутальными методами.…”

“…• модернизировать имеющуюся метрологическое обеспечение скважинной аппаратуры и аппаратуры ГИС с целью повышения точности интерпретации данных до уровня ±2 % (на сегодняшний день ±10 %) и разработки, актуализации и обновления современных методик интерпретации данных ГИС [2];…”
