Abstract
Implementation of modern automation systems on the northern gas fields located at the final stage of operation, is unprofitable economically and is not always possible technically. At the same time, the competent operation of such deposits requires constant monitoring for the state of gas wells and the shelves of the gas transmission network. In particular, the pressure and temperature is obligatory at the mouth of the well and at the end of the shelf. Also an important parameter from the point of view of regulating the modes of the wells is the instantaneous flow rate of the shelf, which is currently not measured at the old deposits. The article proposes to assess the Instantaneous consumption by an indirect method, according to the values of pressure and temperature. The algorithm for calculating the consumption is proposed, the testing of which at the Urengoy gas condensate field confirmed its adequacy. The monitoring system of technological parameters is built into gas fishery ACS. The algorithm visualization is implemented in the SCADA HMI / Cimplicity software package.
Highlights
Most gas deposits in Russia are located in the extreme north, which significantly complicates their development and operation
In the Urengoy oil and gas condensate field (NGKM), gas wells are not electrified, which makes it difficult to equip them with the necessary sensors and technical means of automation [5]
The loops, in turn, are connected to the general collector, by which the gas is fed to the installation of comprehensive gas preparation (ICGP)
Summary
Most gas deposits in Russia are located in the extreme north, which significantly complicates their development and operation. The further development of the ACS of TP on the basis of microprocessor equipment, did not pass the gas industry: new deposits are designed taking into account the concept of "Smart Field", which makes it possible to effectively manage a gas-bearing formation based on collecting and analysing a wide variety of data. As for those deposits that go to the final stage of operation or have already switched to it, the situation is a paradoxical one. In the Urengoy oil and gas condensate field (NGKM), gas wells are not electrified, which makes it difficult to equip them with the necessary sensors and technical means of automation [5]
