Since being put into operation, the unit has been operating stably and has achieved an increase in natural gas production of 110 million cubic meters, marking a solid step forward in the localization of high-sulfur gas field equipment in my country. Behind the 20,000 hours of stable operation is the difficult leap of domestic equipment from "breaking the game" to "leading the way". As the first high-sulfur gas field to be developed on a large scale in China, the Puguang Gas Field was once trapped in the development bottleneck of “decline in formation pressure leading to production decline.” To this end, Sinopec has listed the "high-sulfur gas field pressurization gathering and transportation process" as a major scientific and technological research project in the 13th Five-Year Plan, and will build a sour gas pressurization pilot test project in 2022. The first domestically designed and produced high-sulfur compressor unit with independent intellectual property rights was born. The concentration of hydrogen sulfide in Puguang Gas Field is as high as 15%. In view of the corrosion characteristics of high sulfur content, the company selected special sulfur-resistant and corrosion-resistant materials to upgrade and protect the core components of the unit to improve the wear resistance of the unit. ； Establish a dual guarantee system of "daily inspection + intelligent monitoring" to track the operating parameters of the unit in real time to ensure that the unit is always in optimal operating condition. In addition, the technical team has also carried out a number of technological innovations and process optimizations. By improving the sealing structure, optimizing the lubrication system and other measures, the compressor unit has reached the industry's advanced level in key indicators such as corrosion resistance, wear resistance and automatic control. The successful commissioning of the first domestic high-sulfur compressor unit provides experience and reference for the overall wet gas pressurization of gas fields. The main wet gas boosting project of the Puguang Gas Field will be put into operation in 2024. Currently, the gas field has 3 boosting stations and 9 boosting equipment, with a daily natural gas processing capacity of 12 million cubic meters.
