PROCESS CONTROL SYSTEMS WITH REGARD TO TRANSPORT GAS WAVE PROCESSES

Abstract

It is known that the means for regulating gas extraction processes and processes of the gas flow in the formations are technical devices placed in the wells and surface hydraulic systems. The main problem with the regulation is to identify the relationship between the target process parameters and technical indicators that you want to change. In addition to this, is of great importance order of operations to regulate, ie sequence change technical parameters of certain devices (eg position of the valve shut-off valves). In gas transportation systems as a technical means have a regulating effect, use the puck or controlled by the clearance fittings. Since any change in the hydraulic network structure leads to a redistribution of flows in the elements, you should evaluate how strongly influenced by a complex system mode change control device performance. This kind of problem previously solved in a steady flow in the work of the theory of hydraulic circuits and in later works of industry trends. It is particularly important to note that the processes of transition hydraulic network structure from one steady state to another are no less important to incorporate in the regulation of complex systems. Modeling as a means of control and planning high-impact interventions and operational action on regulatory systems is a unique tool for playback of dynamic processes taking into account the mutual flow of technical devices and geological objects. The main prerequisite for creating a model of unsteady flow in a complex hydraulic network structure is the need to predict the wave phenomena that determine the time to steady state, pressure surges and other phenomena of unsteady flow. In this paper, for the assessment of the state of the fluid (SF) along the length of the pipe (or any other type of link) propose a method for solving the problem of unsteady flow of a compressible fluid with a variable kinematic viscosity in the hydraulic systems of the network structure as those at issue in the hydraulic system.
