Development and testing of two-phase flow meters (DFFM) for non-separation measurement of products component-wise flow-rates, produced from wells of gas condensate and oil and gas condensate fields require special well-equipped and expensive metrological stands. At the same time, to solve some important problems in the density of gas-liquid mixtures (GLM), it is often possible to do with simpler means that simulate such flows. The paper studies the characteristics of a dispersed flow density sensor, herewith, a droplet-liquid aerosol flow is simulated by a water-oil emulsion. A microwave resonator of the decimeter range, partially filled with a dielectric, is used as a densitometer. Minimum concentrations of water aerosol and compressor oil simulating hydrocarbon condensate recorded by a density meter are determined. In case of large ratios of water volumes and oil volumes, a jump in the dielectric constant and a return jump of the gas-liquid mixture (GLM) density corresponding to it were detected, thus reflecting the restructuring of the “water–oil” emulsion internal structure. The method of experimental modeling of the gas-liquid flow density meter can be extended to two-phase flowmeter, developed to register products produced from oil well.

Keywords: two-phase flow meter; gas-liquid mixture; volumetric fraction; natural gas; water; hydrocarbon condensate; decimeter range; gas condensate well.

Specific features of measuring systems construction used to quantitative accounting of oil and petroleum products at storage facilities – tank farms and tank farms facilities – largely depend on the adopted indirect measurement method. With account of modern achievement in the field of measuring equipment development, the method of hydrostatic measurement is a promising one, providing direct measurement of the quantitative accounting basic parameter, namely, oil and petroleum products stock without measuring such parameters as the level, temperature and average density. The article discusses one of the options of the measuring system implementation based on the pressure measuring transducers.

Keywords: measurement; bulk amount of fluid; storage tank; hydrostatic measurement method; errors.

The methods and technologies of geomonitoring of main gas pipelines used in the industry cannot provide prediction of the activation of dangerous geodynamic processes in the near-pipe space. The assessment of the technical state and integrity of "Chusovoy–Berezniki–Solikamsk" pipeline reduces mainly to the determination of the stress-strain state of the pipe without accounting of soils external impact of. One of the ways to solve the problem may be the introduction of an automated monitoring system based on the radio-wave method, which has successfully proven itself at a number of facilities of PJSC “Gazprom”. The system allows to make quick responsible management decisions aimed at eliminating the possibility of accidents occurrence at the earliest stages of development of dangerous natural and man-made processes.

Keywords: stress-strain state; monitoring; main gas pipeline; dangerous geodynamic processes; radio-wave method; geodynamic safety.

The article considers the problem of intellectual monitoring of an oilfield oil pipeline, followed by decisions-making based on the theory of precedents. The main factors characterizing a multiphase mixture flow in the pipeline and affecting the internal corrosion process are presented. The principles of building of a corrosion monitoring system, some specific feature of which include a combination of measuring components and a block of decision-making intelligent support are proposed. A formalized presentation of the situation – the state of the monitoring object is given. An algorithm for finding solutions in the CBR system is given, and the applicability of the solution found in the current situation is estimated based on the search and selection of solutions from the database of cases using well-known approaches.

An important and significant operation when organizing pipeline transportation of natural gas is drawing the balance of natural gas amount. The article discusses the solution of the problem of controlling and detecting the natural gas volumes imbalance by organizing an automatic control system that provides continuous monitoring of the transported gas balance state as well as to predict the places where the imbalances occur. A distinctive feature of the problem solution is the organization of the Mamdani neural-fuzzy system for the main gas pipeline section. Recommendations on the implementation of the automatic control system on programmable logic controllers are given. The article is recommended to specialists that deal with automation of the process of transportation of natural and petroleum associated gas through the main gas pipelines.

Keywords: gas balance; fuzzy logics; neural network; neuro-fuzzy system; Mamdani model.

Invariants of a dynamic system are the functions which remain unchanged during coordinates transformation therefore they characterize qualitative properties of the object under consideration. The article studies some classification problems of the linear stationary finite-dimensional controlled systems under similarity α transformation (change of coordinates in the states space) and σ transformations (simultaneous changes of coordinates in the states spaces and inputs) of G = GL_n(C) × GL_m(C) group. Connection between G-pre-stable points of action σ and stable points of its restriction for a subgroup H = SL_n(C) × SL_m(C) is established.

Keywords: control system; invariant; action; stable system; space; reachable system.
