On February 1, with the completion of the construction of the upper module in the West Coast New Area of Qingdao, Shandong Province, the onshore construction of the comprehensive processing platform for the second phase of CNOOC's "Deep Sea No. 1" project was completed. "Shenhai No. 1" is China's first deepwater high-pressure gas field project. Once the second phase of the project is fully put into operation, the peak annual production of the "Shenhai No. 1" ultra-deepwater gas field will be increased by 50%.
The comprehensive processing platform of the second phase of the "Deep Sea One" project consists of a jacket and an upper module. The total height is about 136 meters, which is equivalent to the height of a nearly 49-story residential building. The total weight is 12,215 tons, which is equivalent to the weight of more than 8,100 cars. . Among them, the jacket is an eight-legged and twelve-skirt pile jacket, which was completed in Shenzhen in mid-January this year. The upper module is composed of east and west parts. Its deck plane is 57.5 meters long and 36 meters wide. The projected area Equivalent to the size of 5 standard basketball courts.
The comprehensive processing platform of the second phase of the "Deep Sea One" project uses a number of domestically produced equipment with completely independent intellectual property rights, including a 7-MW gas turbine generator set, and is equipped with China's largest offshore platform slug independently selected and designed by CNOOC Flow traps are used to eliminate liquid level fluctuations and blockage risks in mixed oil and gas pipelines, ensuring reliable operation of oil and gas processing equipment.
It is reported that the "Shenhai No. 1" ultra-deepwater gas field, which will be put into production in June 2021, has proven geological reserves of natural gas of more than 100 billion cubic meters, a maximum water depth of more than 1,500 meters, and a maximum well depth of more than 4,000 meters. It is the deepest water depth independently developed by China so far. , the most difficult offshore ultra-deepwater gas field to explore and develop. (Produced by Hu Yaojie and Liu Shijiong)
