【摘要】：中國海洋石油渤海LD32-2平臺有3臺燃氣發(fā)電機組和2臺原油發(fā)電機組為整個油田供電。目前,在春季、秋季及冬季三個季節(jié)期間,燃氣發(fā)電機組運行良好,但是夏天氣溫升高,燃氣發(fā)電機組會出現(xiàn)爆燃現(xiàn)象從而導致停機。針對溫度對燃氣機的不利影響,研究如何控制燃氣進氣溫度對提高現(xiàn)有發(fā)電機組的發(fā)電潛力以及節(jié)能增效意義深遠。 本文結(jié)合渤海油田燃氣發(fā)動機的實際需求,開展了燃氣冷卻器制冷系統(tǒng)的工藝設(shè)計、結(jié)構(gòu)設(shè)計與控制系統(tǒng)的設(shè)計,完成了相應產(chǎn)品的現(xiàn)場試驗,取得了較好的研究成果。主要研究內(nèi)容包括： 1、設(shè)計了一種半封閉式壓縮機燃氣冷卻裝置。 在分析現(xiàn)有燃氣制冷技術(shù)中的直接接觸式冷卻和間接接觸式冷卻方式的基本性能基礎(chǔ)上,發(fā)現(xiàn)直接接觸冷卻技術(shù)雖然結(jié)構(gòu)簡單、成本低,但降溫效果差；間接接觸冷卻方式種類繁多,雖然結(jié)構(gòu)相對復雜,但降溫效果好。據(jù)此,本文設(shè)計了一種結(jié)構(gòu)緊湊、成本低的半封閉式壓縮機冷卻裝置。 2、設(shè)計了一套燃氣冷卻器橇裝制冷系統(tǒng)。 根據(jù)實際情況,設(shè)計了一套集板式蒸發(fā)器、風冷冷凝器、半封閉活塞壓縮、節(jié)流裝置、載冷劑水箱、自動控制系統(tǒng)等設(shè)備于一體的整體橇裝式燃氣制冷設(shè)備。 3、根據(jù)系統(tǒng)的控制要求,編寫了相應的控制程序,并對觸摸屏進行了組態(tài),通過PLC和觸摸屏結(jié)合,豐富了PLC的控制功能,同時也使控制操作變得更加靈活、簡單。觸摸屏對燃氣冷卻器現(xiàn)場的實時參數(shù)進行顯示,包括溫度值、壓力值、壓縮機運行狀態(tài)、冷凝器運行狀態(tài)等,使整套燃氣冷卻器橇裝制冷機組運行更加可視化。 4、對研制的整套設(shè)備進行現(xiàn)場安裝調(diào)試,結(jié)果證實系統(tǒng)運行穩(wěn)定、可靠,達到了設(shè)計及工程要求,能取得良好的控制效果,燃氣冷卻器橇裝制冷機組能輸出滿足燃氣發(fā)電機燃氣溫度值的要求。 總之,燃氣冷卻器橇裝機組結(jié)構(gòu)緊湊、占地面積小、開機速度快,能滿足海上油田工程的應用要求。
[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.
