In 2019, the world’s first 2000 Nm³/h, 70 MPa dual-medium reciprocating compressor unit, developed independently by Core Oil, passed customer inspection and was shipped to an oil field area in Karamay for use in gas injection operations to increase production in deep and ultra-deep oil wells. This set of compressors has broken the highest records for exhaust pressure of reciprocating compressors in the oil and gas field industry both domestically and internationally, enabling China to reach an international leading level in the design and manufacturing of reciprocating compressor skids, thus taking the lead in China’s \"high-pressure era\".
As oil and gas exploration and development continue to extend into deeper geological formations, the scale of deep well drilling is increasing. Currently, 39% of China’s remaining oil reserves and 57% of its remaining natural gas reserves are located in deep reservoirs, making deep onshore areas an important area for the continuation of China’s energy strategy. The Karamay Oil Field, located in the Junggar Basin, is a key area for replacing China’s oil production. It is rich in gas and oil reservoir resources, but the average burial depth exceeds 7,000 meters; moreover, its geological structure is complex, characterized by ultra-deep depths, ultra-high pressures, and ultra-high temperatures. As the level of development continues to increase, the overall difficulty of extracting oil and gas also rises, which places higher demands on equipment and technology. Large-capacity, high-pressure boosting equipment capable of converting nitrogen and highly sulfur-containing natural gas has become key to the development of oil reservoirs in Xinjiang at present. The industry’s development trends and customers’ urgent demands spurred Coray Petroleum’s R&D team to resolve the challenge of breaking into the 70MPa \"unexplored realm\".
Leveraging its extensive technical expertise and practical experience, and taking into account the local well conditions as well as the harsh operating environments on site, Core Oil’s R&D team has overcome various technical challenges, including high-frequency airflow fluctuations, dynamic vibrations in compressors under high pressure and high flow rates, corrosion caused by hydrogen sulfide gas, and the need to meet the requirements of dual-operating-mode process flows. This device boasts numerous advantages: it features an exhaust pressure of up to 70 MPa and a flow rate of 2000 Nm³/h; it is capable of converting between nitrogen and natural gas with high sulfur content, thus filling a gap in international technology ； It features an intelligent integrated control system, offering a high degree of automation; remote operation reduces the need for manual labor, and it enables open and flexible system interconnection, facilitating the integration of automation and information technology ； The temperature range of from -30°C to +50°C is designed to fully meet the operational requirements in Xinjiang’s various conditions; the equipment boasts high stability, enabling 6,000 hours of fault-free operation throughout the year.
? In 2006, Core Oil introduced nitrogen equipment with a capacity of 1200 Nm?/h and 35 MPa pressure； ? In 2014, nitrogen equipment with a capacity of 1200 Nm?/h at 50 MPa, 2000 Nm?/h at 50 MPa nitrogen compressors, as well as dual-media compressor units were introduced one after another ； In 2015, 2600KW coalbed methane compression units were shipped to Australia, and Core Oil became the only Chinese company to enter Australia’s high-end market ； ? In 2016, reciprocating compressor units for LNG gas-liquid transport in the Arctic were shipped to Russia to serve the world’s largest liquefied natural gas project ； In 2017, Core Oil took the lead in drafting the standard for \"Nitrogen Generation and Injection Equipment for Oil and Gas Drilling and Production\", shifting from being a standard implementer to a standard setter and using its technical expertise to gain influence in the industry ； In 2019, Core Oil shipped high-power natural gas reciprocating compressors customized for an Egyptian client; this shipment marked a new breakthrough for Chinese compressor products entering the Egyptian market.
Design it a bit taller, so it will be easier to meet in the future. https://bbs.hcbbs.com/thread-3363768-1-1.html (Source: Huahai Chuanliu – Haichuan Chemical Industry Forum)
