Maintaining the reliability of ball valves during operation in winter in the Far North

One of the most important tasks determining the safety of the environment during operation and maintenance of ball valves in the winter in the Far North is the efficiency and trouble-free operation of the gas pipeline.

The frequency of the complex of operations TO-2 is carried out according to the approved schedule of work 1 every 6 months.

Seasonal maintenance of the TO-2 is carried out in the preparation of valves for the autumn-winter and summer periods of operation.

The restoration of the ball valve performance is presented in two variants: 1 – without a project; 2 – with a project.

Internet of Things and WSN technology applications in Oil and Gas industry

Digital technologies are a considerable factor in the oil and gas industry. In the post-Internet global information era, the Internet of Things (IoT) paradigm is consid-ered as both technology and economic wave. Wireless sensor networks (WSN) repre-sent one of the key enabling technologies for IoT. IoT connects all things to the Internet and between each other and achieves the goal of intelligent identifying, managing, monitoring, locating, and tracking as well. In this paper WSN and IoT some interesting applications in oil and gas industries around world were represented.

Suppression of the reverse energy flow of an induction motor as a factor of increasing the electrical safety of the electrical complex

The industrial operation of mine precinct electrical complexes is associated with the probability and risks of damaging flexible cables of power connections and, as a consequence, the occurrence of accidents and hazardous electrical conditions.

It is established that the protective shutdown function of multi-machine, power-ful electrical systems is insufficient, and priority should be given to automatic two-way de-energization of emergency power connections.

The rationality of the effect of induction-dynamic braking of an induction motor of a consumer as a means of suppressing its reverse energy flow in the case of an emergency (dangerous) condition of the supply cable is proved

Methods of statistical evaluation of the dynamics of dehydration of fixed volumes of oil emulsions under the influence of a rotating electromagnetic field

The article describes the method of statistical evaluation of the separation of resistant oil emulsions under the influence of a rotating electromagnetic field. At the same time, verification procedures were performed to assess the reliability of experimental results. Single-factor dependences are obtained for the predictive calculation of the water content parameter S as a function of the induction value B of a rotating electromagnetic field with a known optimal exposure time t. The dependence B = f(S) at t = const was also obtained, which allows us to estimate the magnitude of induction B of the rotating electromagnetic field required for the process to achieve a given value of water content S when the oil emulsion is dehydrated. A two-factor dependence of the form S = f(B, t) was also obtained, which allows to evaluate the efficiency of dewatering the emulsion in the case of various combinations of the parameters B and t. The quality assessment of the two-factor linear model was made by a statistical method.

Frost resistance of concrete with the addition of expanded polystyrene

In construction it is necessary to solve questions of improvement of quality, durability, effectiveness of concrete and reinforced concrete. One of the major reasons for the increase of durability and lifetime of structures is to increase the frost resistance of concrete.
Frost resistance determines the durability and reliable operation of the structures. Frost destruction of concrete reduces the lifespan of structures, reduces the time between overhauls cycles, leading to high costs for repair and recovery.
Research topic involves the implementation of scientific and practical researches in the field of increase of frost resistance of concrete due to the use of polystyrene foam.

Design of new installations for operation of multilayer oil wells

A multipacker installation (MPI) has been designed, which allows operating 3 or more layers separately. The device UORE-RPP has been designed that allows switching stream flows between the layers to operate only one of them, while for operating the other layer it is necessary to perform refitting of plungers. Both of the developed installations were implemented on wells of JSC “Sheshmaoil”, and positive results were achieved. A patent has been obtained.
