[Abstract]:China offshore oil Bohai LD32-2 platform has 3 gas generating sets and 2 crude oil generating sets for the whole oil field. At present, in the spring, autumn and winter three seasons, the gas generating set is running well, but the temperature rises in the summer, the gas generating set will burst and lead to the shutdown. It is of great significance to study how to control the intake temperature of gas to improve the power generation potential and energy efficiency of the existing generating units.
In this paper, based on the actual demand of gas engine in Bohai oilfield, the process design, structure design and control system design of the gas cooler are carried out, and the field test of the corresponding products has been completed, and the good research results have been obtained. The main contents include:
1, a semi closed compressor gas cooling device is designed.
Based on the analysis of the basic performance of direct contact cooling and indirect contact cooling in existing gas refrigeration technology, it is found that the direct contact cooling technology is simple in structure and low in cost, but is poor in cooling effect, and there are many kinds of indirect contact cooling methods. Although the structure is complex, the cooling effect is good. This paper has designed this paper. A semi enclosed compressor cooling device with compact structure and low cost.
2, we designed a set of skid mounted refrigeration system for gas cooler.
According to the actual situation, a set of overall sled gas cooling equipment, such as plate evaporator, air cooling condenser, semi closed piston compression, throttle device, refrigerant tank, automatic control system and so on, is designed.
3, according to the control requirements of the system, the corresponding control program is written, and the touch screen is configured. Through the combination of PLC and touch screen, the control function of PLC is enriched. At the same time, the control operation becomes more flexible and simple. The touch screen displays the real-time parameters of the gas cooler, including the temperature, pressure value, compressor transport. The operation status of the condenser and the running state of the condenser can make the whole gas cooler skid mounted refrigeration unit run more visually.
4, the whole set of equipment developed in the field is installed and debugged. The results show that the system is stable and reliable. The design and engineering requirements can be achieved. Good control effect can be achieved. The gas cooler sled refrigerating unit can meet the requirements of gas generator gas temperature.
In short, the gas cooler skid mounted unit has compact structure, small occupied area and fast start-up speed, which can meet the application requirements of offshore oilfield engineering.
