ABSTRACT

The article discusses the existing methods of deactivation of pyrophores-iron sulfides, examines their shortcomings, indicates the number, proportions of effective deactivating components and conditions for their use.

A significant part of fires and explosions in the oil, gas and petrochemical industries are caused by self-igniting pyrophores-iron sulfides. The most common iron sulfide compounds in production are FeS, FeS2; F2S3. These compounds, reacting with oxygen in the air, self-ignite and burn, causing a fire, explosion of technical means used in the transportation and storage of oil and petroleum products.

Taking this into account, an effective method of decontamination of pyrophoric deposits has been developed. The proposed composition transforms pyrophoric substances into non-pyrophoric ones, being a foaming agent. The process is characterized by the simplicity of its own method of preparation and use, significantly lower cost.

Pyrophor-a composition passivating iron sulfide, consists of sodium salt (ntnd) naphthenic acid and an aqueous solution of foam-stabilizing polyacrylamide (paa).

Keywords: Pyrophor, iron sulfide compounds, sulfide compounds of petroleum products, naphthenic acids, inhibitors, polyacrylamide (paa), foaming agent reactor.

ABSTRACT

The first oil well in the world was drilled in Bibiheybet in 1846 by industrial method (mechanical drilling) and later by drilling in Balakhani in 1871 using impact technology, it turned Azerbaijan into the center of oil production. As a result of the analysis of the country's oil exploration, it was determined that during the past years, over 30,000 oil and gas wells in the land and sea areas have been drilled, and exploited and in the end, their activities were suspended, conserved, or canceled. Currently, the stock of wells in operation is slightly more than 6000. In these processes, environmental imbalances in the areas of oil and gas mines, and pollution of land and water areas, as well as led to the occurrence of serious deviations in the underground.

On the other hand, the technology of decommissioning expired wells requires updating, where not only the cleaning of the polluted oil areas but also the solution to the problems related to the recultivation of the subsoil in the zones are of great importance.

Despite a wide range of scientific research works that have been carried out in the direction of the development of existing methods of decommissioning wells, the issue of the full assurance of the hermeticity of decommissioned wells is considered to be a problem.

On the other hand, the corrosion of protective belts, the absence of cement stone rings behind the belt, as well as the collapse of cement bridges lead to an increase in the probability of the formation of a connection between the productive layers and the ground surface, causing residual oil and gas to flow to the surface in later decommissioned wells [1-3].

For this reason, the presented article is dedicated to the analysis of the current situation of oil well cancellation, restoration, and subsoil recultivation problems and the development of relevant recommendations.

Keywords: oil and gas mines, canceled wells, environmental hazard, underground reclamation, hermeticity.

ABSTRACT

Among the properties associated with ensuring the necessary level of reliability of oil and gas field equipment, a special place is occupied by the safety of service personnel. The source of increased danger is installations used for drilling oil and gas wells and their underground repair, as well as a number of other field facilities.

Modern oil and gas field equipment is a technical system operating in difficult conditions, and with an increase in the depth of wells, these conditions are significantly complicated. When drilling wells, significant loads are applied to individual units and mechanisms. In addition, the maintenance of many types of oil and gas field equipment is associated with the presence of personnel in the immediate vicinity of working mechanisms, especially during descent and lifting operations on drilling rigs with traditional hoisting system, rotor and swivel. At the same time, significant loads acting on the talus system create prerequisites for the occurrence of dangerous situations, which often leads to occupational injuries.

The article is devoted to assessing the reliability of oil and gas field equipment with the necessary level of safety.

Keywords: reliability, oil and gas field equipment, working personnel, safety, well.

ABSTRACT

In this paper, on the basis of well-known technical, constructive and organizational solutions, an analysis is carried out to improve the efficiency of the transmission of the rocking machine. The subject of this dissertation is the possibility of using a chain transmission in the transmission instead of the V-belt transmission of the rocking machine used for years, as well as the issue of non-stop operation of pumping units of the rocking machine during floods and flooding, when the water level rises to the electric motor and there is a forced stop of oil supply to production. The efficiency of chain gears under favorable conditions can reach 0.97 – 0.98. The purpose of developing a chain drive simulation program is to analyze dynamic phenomena in chain drive systems and study various design changes in systems in order to eliminate undesirable phenomena. In this case, an electric motor with a transmission, which includes a gearbox and a chain transmission, is mounted directly on the scales, and connecting rods that are connected at one end to cranks mounted on the driven shaft of the scales. the gearbox, and at the other end are pivotally fixed to the pump unit housing. Formulas are given that are used to determine the torque and forces that act on the mechanism, as well as approximate graphs are given. In this paper, a new formulation has been developed for modeling the dynamics of roller chain drives using the continuous contact force method. The model of the contact surface between the rollers and the asterisk showed that this is an important issue concerning the numerical stability of the simulation program, and the model with a real tooth profile proved its superiority over other models used. Thanks to the application of this method, it is shown that the interconnected dynamics of elements in the chain drive system is captured and the contact problem is characterized. The chain drive model is compared with simplified analytical results, while the necessary experimental verification is left for future research.

Keywords: pump jack, transmission, V-belt transmission, chain transmission, balancer.
