7月10日，全球首个超深层高含硫生物礁大气田——元坝气田累计生产天然气量突破400亿立方米，通过“川气东送”管道惠及长江沿线6省2市近2亿居民，为保障国家能源安全、支撑长江经济带高质量发展注入了清洁能源动能。

On July 10th, the world's first ultra-deep, high-sulfur bio-reef gas field - Yuanba Gas Field - has achieved a cumulative production of over 40 billion cubic meters of natural gas. Through the "Chuan Gas Eastward Transmission" pipeline, it has benefited nearly 200 million residents in 6 provinces and 2 cities along the Yangtze River, injecting clean energy momentum into the safeguarding of national energy security and the high-quality development of the Yangtze River Economic Belt.

元坝气田位于四川盆地东北部的苍溪县和阆中市等地，探明天然气地质储量3030亿立方米，已建成年产天然气40亿立方米、年产硫黄30万吨的稳定生产能力。

The Yuanba Gas Field is located in the northeastern part of the Sichuan Basin, in areas such as Cangxi County and Langzhong City. It has an identified geological gas reserve of 303 billion cubic meters. It has achieved a stable production capacity of 4 billion cubic meters of natural gas and 300,000 tons of sulfur per year.

中国石化西南石油局有限公司董事 刘伟：今年以来，元坝气田保持高位平稳运行，日产天然气稳定在1100万立方米以上。

Liu Wei, a director of Sinopec Southwest Petroleum Bureau Co., Ltd.: Since the beginning of this year, the Yuanba gas field has maintained a stable and high-level operation, with the daily output of natural gas remaining above 11 million cubic meters.

作为全球埋深最大、开发难度最高的高含硫生物礁气田，元坝气田的开发长期被公认为油气领域的世界级难题。气藏平均埋深超7000米，最深井达8200米，地下最高温度160摄氏度，同时兼具超深、高温、高压、高含硫四大开发挑战，地下礁体形态复杂、储层识别难度极大。为破解资源识别难题，攻关团队对气藏进行了3轮共计2288平方公里的精细勘探，清晰描绘出了7000米地下的4条礁带、21个礁群、90个单礁体，预测出礁体中30米左右优质储层。

As the world's largest gas field with the deepest burial depth and the most challenging development, the Yuanba gas field has long been regarded as a world-class problem in the oil and gas industry. The average burial depth of the gas reservoir exceeds 7,000 meters, and the deepest well reaches 8,200 meters. The underground temperature can reach 160 degrees Celsius. At the same time, it also presents four major development challenges: ultra-deep, high temperature, high pressure, and high sulfur content. The underground reef structure is complex, and the identification of the reservoir is extremely difficult. To solve the problem of resource identification, the research team conducted three rounds of detailed exploration covering a total area of 2,288 square kilometers. They clearly delineated 4 reef belts, 21 reef groups, and 90 individual reefs at a depth of 7,000 meters underground, and predicted high-quality reservoirs of about 30 meters in thickness within the reef bodies.

中国石化西南石油局有限公司董事 刘伟：我们持续迭代核心技术，创新形成了成套控水稳气、一井多礁技术系列，为我国乃至世界超深层油气资源规模效益开发提供借鉴。

Liu Wei, Director of Sinopec Southwest Petroleum Bureau Co., Ltd.: We have continuously refined our core technologies and innovatively developed a series of water control and gas stabilization technologies as well as a single-well multi-reservoir technology, which provides a reference for the large-scale and efficient development of ultra-deep oil and gas resources in China and around the world.

自2016年投产以来，元坝气田累计生产天然气突破400亿立方米，相当于减少二氧化硫排放超660万吨，在保障长江经济带能源供给的同时助力绿色低碳发展。

Since its commissioning in 2016, the Yuanba Gas Field has cumulatively produced over 40 billion cubic meters of natural gas, equivalent to reducing sulfur dioxide emissions by more than 6.6 million tons. This has not only ensured the energy supply for the Yangtze River Economic Belt but also contributed to green and low-carbon development.

我国生物礁型油气资源丰富

Our country has abundant bio-reef type oil and gas resources.

生物礁油气藏是全球油气增储上产的重要领域，我国生物礁型油气资源禀赋优异、分布广泛，随着勘探开发技术不断突破，正逐步成为保障我国油气自主供应的重要接替资源。

Bio-reef oil and gas reservoirs are an important area for increasing global oil and gas reserves and production. China has abundant and widely distributed bio-reef oil and gas resources. With the continuous breakthroughs in exploration and development technologies, they are gradually becoming an important alternative resource to ensure China's independent supply of oil and gas.

我国具有“富煤、贫油、少气”的资源特点，是油气进口大国，生物礁油气（藏）田是油气藏勘探开发的重要领域，在世界油气探明总储量中约占10%。我国生物礁型油气资源十分丰富，目前已在陆上四川盆地、塔里木盆地、鄂尔多斯盆地深层及超深层和南沙海域诸盆地中发现大量生物礁油气藏。在四川盆地，已开发普光气田、元坝气田、龙岗气田3个生物礁大气田，探明储量超6000亿立方米，是“川气东送”重大工程的主供气源之一。

Our country has the characteristic of "abundant coal resources, scarce oil resources and limited gas resources". It is a major importer of oil and gas. Biologic reef oil and gas fields are an important area in oil and gas exploration and development. They account for approximately 10% of the total proven oil and gas reserves in the world. Our country has abundant biologic reef oil resources. So far, numerous biologic reef oil fields have been discovered in the deep and ultra-deep layers of the Sichuan Basin, Tarim Basin, Ordos Basin on land, as well as in the South China Sea basins. In the Sichuan Basin, three biologic reef gas fields - Puguang Gas Field, Yuanba Gas Field and Longgang Gas Field - have been developed. The proven reserves exceed 600 billion cubic meters, making them one of the main gas supply sources for the "West-to-East Gas Transmission" major project.
