中国渤海首个千亿方大气田累计产气突破10亿立方米，保障京津冀及环渤海地区用气需求
中新社北京8月24日电 (记者 王恩博) 中国海油24日发布消息，中国渤海首个千亿方大气田——渤中19-6气田累计生产天然气超过10亿立方米，有力保障了京津冀及环渤海地区的用气需求。
渤中19-6气田位于渤海中部海域，区域平均水深约20米，已探明天然气地质储量超2000亿立方米、探明石油地质储量超2亿立方米，是中国东部第一个大型、整装的千亿方大气田。该气田试验区和一期开发项目分别于2020年10月、2023年11月投产。目前已建成海上油气平台6座，高峰日产天然气达到240万立方米，产能建设进入快速上升阶段。
据中国海油渤海石油研究院开发地质资深工程师程奇介绍，渤中19-6气田的油气埋藏在深度超5000米的潜山储层，布置的开发井平均井深5598米，深度超过6000米的超深井多达20口，最深的达6494米，对勘探开发工程技术要求极高。
该气田的成功开发，标志着中国在超深层油气勘探开发领域取得重大突破。目前，渤中19-6气田已经成功实施了两口超深井，地层温度超过180摄氏度，井底压力达到56兆帕，油气储存在只有0.01至0.1毫米宽的裂缝中，相当于在头发丝中抽取油气。
中国海油天津分公司副总经理张春生表示，现阶段，渤中19-6气田开发已进入油气上产的关键时期，随着项目建设稳步推进，科研人员对气田储层分布规律和油藏地质特征的认识进一步加深，对后续气田安全高效开发具有重要实践意义，将有力推动渤海海域超深层领域大型油气资源的规模性开发。
渤中19-6气田的成功开发，不仅为京津冀及环渤海地区提供了稳定的天然气供应，也为中国深海油气勘探开发积累了宝贵的经验，为中国能源安全提供了有力保障。未来，中国海油将继续加大对渤海海域的勘探开发力度，为中国经济社会发展贡献力量。

Bohai Gas Field Produces Over 1 Billion Cubic Meters of Gas,Guaranteeing Supply for Beijing-Tianjin-Hebei and Surrounding Areas

BEIJING, Aug. 24 (Xinhua) — China National Offshore Oil Corporation (CNOOC) announced on Tuesday that the Bozhong 19-6gas field, the first trillion-cubic-meter gas field in China’s Bohai Sea, has produced over 1 billion cubic meters of natural gas, effectively securing gas supply for Beijing-Tianjin-Hebei and the surrounding Bohai Sea region.
Located in the central Bohai Sea with an average water depth of about 20 meters, the Bozhong 19-6 gas field has proven natural gas reserves exceeding 200 billion cubic meters andproven oil reserves exceeding 200 million cubic meters. It is the first large-scale, fully-equipped trillion-cubic-meter gas field in eastern China. The field’s pilot area and Phase I development project were put into operation in October 2020 and November 2023,respectively. Currently, six offshore oil and gas platforms have been built, with peak daily natural gas production reaching 2.4 million cubic meters, and production capacity construction is entering a rapid growth phase.
According to Cheng Qi, a senior development geologist at CNOOC Bohai Oil Research Institute, the oil and gasof the Bozhong 19-6 gas field are buried in a sub-mountainous reservoir at a depth of over 5,000 meters. The average well depth of the developed wells is 5,598 meters, with over 20 ultra-deep wells exceeding 6,000 meters, the deepest reaching 6,494 meters. The project places extremely high demands on exploration and development engineering technology.
The successful development of this gas field marks a significant breakthrough in China’s ultra-deep oil and gas exploration and development. Currently, two ultra-deep wells have been successfullyimplemented in the Bozhong 19-6 gas field, with a stratum temperature exceeding 180 degrees Celsius and a bottom-hole pressure reaching 56 megapascals. The oil and gas are stored in cracks only 0.01 to 0.1 millimeters wide, equivalent to extracting oiland gas from a hair.
Zhang Chunsheng, deputy general manager of CNOOC Tianjin Branch, said that the Bozhong 19-6 gas field development has entered a crucial period for oil and gas production. As the project construction progresses steadily, researchers’ understanding of the gas field’s reservoir distribution patternsand reservoir geological characteristics has deepened, which is of significant practical significance for the subsequent safe and efficient development of the gas field. It will strongly promote the large-scale development of large oil and gas resources in the ultra-deep layer of the Bohai Sea.
The successful development of the Bozhong 19-6 gas field not only provides a stable supply of natural gas for the Beijing-Tianjin-Hebei and surrounding Bohai Sea region but also accumulates valuable experience for China’s deep-sea oil and gas exploration and development, providing strong support for China’s energy security. In the future, CNOOC willcontinue to increase its exploration and development efforts in the Bohai Sea to contribute to China’s economic and social development.
