On July 3, it was learned from the Sinopec Information Office that Sinopec deployed in the Hai 3 inclined well in the Weixi exploration area of the Beibu Gulf Basin in the South China Sea to test high-yield industrial oil and gas flow, which was converted into a daily output of 738 cubic meters of crude oil, 280,000 cubic meters of natural gas, and 1,010 cubic meters of oil and gas equivalent, setting a record for the highest daily oil and gas production in the Beibu Gulf sag. The breakthrough of this well confirms the further exploration and development potential of Weixi Exploration Area, and provides strong support for Weizhou Oilfield to further expand the scale of reserve increase and production.

Innovative theoretical research and successful acquisition of the "treasures" of the deep ocean. The Beibu Gulf Basin is one of the six major oil-bearing basins along the coast of mainland China, with abundant oil and gas resources. Previously, Sinopec made a breakthrough in the Weizhou Oilfield in the Beibu Gulf Basin, with reserves of 10 million tons, and is currently in the production capacity construction stage. The northern part of the sea depression where the Hai 3 inclined well is located is the target area for increasing reserves and expanding production in Weizhou Oilfield, which was deployed and implemented in March this year. The well has an operating depth of 4,600 meters, including a horizontal displacement of 1,300 meters, a bottomhole temperature of 150 °C and a bottomhole pressure of 73 megapascals. In the process of drilling, the operators successively overcame the problems of difficult to drill ash-bearing formations and dense coal seams that are easy to collapse, and finally successfully drilled and obtained good oil and gas displays.

Zhao Yong, Secretary of the Party Committee and Executive Director of Sinopec Shanghai Offshore Oil Bureau, said that in the next step, the company will further increase the integration of exploration and development and engineering. In terms of exploration, we will speed up the evaluation of high-quality scale potential areas and the research on the resource potential of new strata in the new area, and implement the next large-scale reserve position in the area. In terms of development, we will continue to carry out research on the optimization of the development plan of Weizhou oilfield, and actively expand the scale of Sinopec's production capacity construction in deep-sea oil and gas fields. In terms of engineering, in view of complex geological conditions such as high-temperature and high-pressure wells in the South China Sea, the scheme design is optimized, construction management is strengthened, and safe and efficient operation is realized.

From land to sea, it will help the development of offshore oil and gas industry in the mainland. The mainland is rich in offshore oil and gas resources, which is an important area for long-term and substantial production increase. Sinopec Shanghai Offshore Oil Bureau focuses on the exploration and development of medium and deep-sea oil and gas and engineering services, its predecessor is the first offshore oil exploration team in New China, the exploration and development of oil and gas fields in the Bohai Sea, the Yellow Sea, the East China Sea, the South China Sea and overseas waters, has discovered 19 oil and gas fields such as Pinghu and Chunxiao, achieved a major strategic breakthrough in oil and gas in the East China Sea and the South China Sea, and made positive contributions to the development of the national offshore oil and gas industry. In addition, Sinopec Shengli Oilfield has been offshore exploration and development since 1993, and has built the largest shallow sea oilfield in China with a capacity of 3 million tons, with a cumulative production of more than 73 million tons of crude oil and more than 3 billion cubic meters of natural gas.
