METHOD FOR REMOVING WELLS INTERDRIVING IN GAS COLLECTING FLOWLINES OF HIGH NORTH GAS FIELDS

摘要

FIELD: oil and gas industry.;SUBSTANCE: method includes the assignment of its operation modes within the process limits, which are determined by the calculation method, based on the results of gas-hydrodynamic wells researches. At that during the field operation, using the telemetry and automatic process control systems of the complex gas treatment unit (CGTU), measure with the specified quantization step the actual gas pressures at the collector of each well cluster and at the end of the gas collecting flowlines (GCF), and the gas flow of each well cluster, and using the measured data and the passport characteristics of the GCF in the real time scale, calculate the gas pressure at the pumping points and make the time-synchronized graphs of pressure pairs: the measured at the collector's cluster and calculated for the pumping point, to which it is connected and the pressure measured at the end of GCF as well and calculated for the last pumping point before the CGTU, and, as soon as it is found, that one of the pressure difference pairs becomes less than the specified threshold, the value of which is assigned, based on the results of the last gas-hydrodynamic well tests and the CGTU specified operation mode, the CGTU operator is given the report on identifying the problems in the GCF work and/or the corresponding cluster of the gas wells, as well as the recommended list of individual operations sequences of the situation appeared on the problem section correction, and using this list, the operator of the plant takes the final control solution to fix the problem.;EFFECT: determination accuracy increase of the gas collecting flowlines operation mode correct selection with the common collector in the real time scale.;2 dwg
