Abstract

The observed instability of the oil and gas market makes it necessary to intensify the exploratory scientific research for the development of advanced and inexpensive pumping and compressor equipment intended for oil and gas production and treatment. The ongoing research work is being undertaken with a view to modernize well-known technical solutions and develop new scientific principles for gas compression with the use of labyrinth compressors. From the published materials, it became known that when designing labyrinth pumps, the screw auger on the pump rotor can be replaced with a set of vane wheels. This design approach should be transferred from the field of pumping technology to the field of compressor technology as well. At the initial stage of such research microlevel models of new turbocompressors have been developed to test their performance. Further, was made the transition from the low-cost physical experiments with micro-level models to a deeper study of the working process for the basic model of the compressor with the screw rotor. 3D-model development was carried out with the use of the SolidWorks 3D CAD-system. In order to undertake a calculation study, the FloEFD software package of computational fluid dynamics developed by Mentor Graphics Corporation has been used. The results of the research findings can be used for the development of energy-efficient technologies for the compression and pumping of various gases. The development of cheaper and more economical pump-compressor units will allow for the solution of urgent hydrocarbon exploration and production problems in abnormal operating conditions. Based on similar compressor units, there is a possibility to develop other sectors of science and technology as well.

Highlights

At the late stage of oil and gas field development, the need for additional pumping and compressor equipment is increasing due to reduced reservoir pressure
In our opinion, there is a promising direction of work in the field of labyrinth pumps and compressors, related to the application of alternative rotor variants that can compete with the screw rotor, according to previous publications [10,11,12], especially at a higher rotation speed
In the framework of exploratory scientific research, the basic principles of designing the mesh rotor for turbomachinery equipment have been developed and patented. Such rotor can withstand higher loads due to its increased structural rigidity. It is known from recently published materials that when designing labyrinth pumps, the screw on the pump rotor can be replaced with a set of vane wheels

Summary

Introduction

At the late stage of oil and gas field development, the need for additional pumping and compressor equipment is increasing due to reduced reservoir pressure. In this case, in one of the variants, the control is performed by changing the cross-section area in the flow channel at the nozzle, as described in patent [6]. The cyclic mode of the working medium flow through the nozzle of the jet device is considered. In this case, cyclical changes in the jet's operating parameters are provided by the rotating disc, which is located inside the nozzle, as described in patents [7,8,9]
