ADAPTATION ACOUSTIC SENSORS, WARNING DEVICES OF SAND AND CONDENSED MOISTURE DSP-EAC-2 IN THE TECHNOLOGICAL LINE GAS COLLECTION POINTUNDERGROUND GAS STORAGE

摘要

Carried out fishing activities on adaptation-alarm sensor (DS) and the removal of layers of sand condensed moisture DSP-EAC-2 on the technological line of gas gathering points (GSP) Stavropol underground gas storage (UGS) and Kasimov U Kasimov industrial site of the Office of underground gas storage (UPHG). An essential dependence of sensitivity DS on the installation location, configuration and design features of the operating equipment. The article focuses on the basic principles of calibration modification DS DSP-EAC-2 levels of controlled phases (liquid and solid mechanical impurities) separation methods on the metering Threads GSP, as well as in the process of gas-dynamic studies of wells. Experimental data of the 1st stage adaptation of the sensor DSP-EAC-2 at 108-114 mm diameter pipes. Calibrations The results agree well with the data of the monitoring wells modes. The optimum installation location DSP-EAC-2 based on DC operating conditions. Recommended values are controlled by seven exceedances of water factor for Stavropol UGS and Uvyazov UPHG. It has been shown that it is not advisable to use DSP-2 EAC to monitor the content of sand and water (ERW) on the metering Threads GSP wells in the vicinity of the flow regulating type valves regulating gas control devices (KRU) of the high level of background noise signal. Calibration of acoustic sensors in the gas stream is a prerequisite for obtaining reliable evidence, because it allows to take into account the actual loss of the acoustic signal in the actual configuration of the pipe at the sensor. Uses for normalizing the sensor readings on the level of the acoustic signal by debit gas flow without mechanical impurities is impractical because of the large background used on the thread orifice flow equipment (switchgear). We propose a specific terminology to be used in further work.
