Abstract: The article is dedicated to the solution of the problem of operational control of complex multiphase flows of production wells, characterized by high gas factors and presence of impurities of sand and/or water. It is shown that for a reliable evaluation of the well operation mode it is necessary to carry out complex moni-toring of such basic parameters as the production rate and the dynamics of its change, the component composition, wellhead pressure and the temperature of the extracted production. This information is necessary to select a highly pro-ductive and trouble-free operating mode of the well. For practical implementation of complex monitoring, a low-energy information-measuring system of the new generation «Potok-6» was proposed. The article presents a functional scheme for processing information signals. The time diagrams of the sand registration chan-nel operation are presented and the advantages of new technical solutions are specified

Author of 14 scientific publications in the field of humidity measurement of oil.E-mail: martynov@gubkin.ru

Abstract: Development of new transducers of water content of oil with higher measurement accuracy and sensitivity is an important task, since the use of existing electric moisture meters of both commodity and crude oil is significantly limited in operating conditions. A considerable additional error up to 1-5 %, occurs when the resistance of the formation water in the emulsion bypasses the capacity of the measuring sensor. The article discusses the digital pulse electric transducer of water content with automatic error correction, taking into account the influence of the conductivity of water-oil emulsion

Abstract: The article is devoted to solving the problem of registration of liquid impurities (water) in the multiphase flow of gas producing wells. To solve the problem flow characteristics were studied in laboratory using a piezoelectric transducer. The results were processed using ANOVA techniques of factorial design. The optimal frequency range for finding the parameters of the impact of dropping liquid impurities and determining its amount was identified.

Abstract: The presented article deals with designing the model and researching the characteristics of the sensor of pressure pulsation used in well flow measuring modules of «Potok» series measuring systems. Cylindrical piezoceramic elements protected from direct action of the measured medium by the special stainless steel construction are used in the involved measuring converter as a sensor element. The results of the experimental research of the with four types of domestic and foreign piezoceramic elements are given in this work. Climatic tests for different variants of the construction to reach stable time and temperature characteristics of the original measuring converter were conducted.
