Description

The laboratory stand is designed to study the method of lifting oil using gas lifts and to study the movement of the gas-liquid mixture in the well. The measurement results are displayed on digital indicators and in parallel on the computer. Processing of research results is carried out by a computer program. At the same time, you can process the results manually. The stand includes three rows of transparent vertical pipes, united by a common inlet simulating an oil-bearing formation, and provides the following laboratory work in the discipline “Operation of oil and gas wells”: – monitoring the operation of a gas-liquid lift; – determination of the structure of the ascending flow of the gas-liquid mixture; – study of the operation of a gas-liquid lift during constant immersion under a dynamic level; – obtaining experimental lifting curves and determining the parameters of the optimal and maximum operating modes of the gas-liquid lift; – study of the influence of relative immersion on the operation of a gas-liquid lift, experimental obtaining of lifting curves at different immersion under a dynamic level and determination of the nature of the influence of relative immersion on the operation of a gas-liquid lift; – determination of the efficiency of an experimental gas-liquid lift; – study of the method of evacuation (separation of air from liquid) of a gas-liquid mixture. The stand includes: – three models of gas-liquid lift with casing columns; – measuring capacitance; – system for maintaining the required fluid level; -compressor; – air flow measurement sensor with information output to a digital indicator; – gas-liquid mixture evacuation system; – liquid flow measurement system; – pressure measurement sensors with information output to a digital indicator; – ADC board; – laptop with software.
