国际标准化组织近日正式发布由我国牵头制定的5项天然气领域国际标准。将通过精准的量化指标，为全球能源市场提供降本增效与安全保障的“中国方案”。

The International Organization for Standardization recently officially released five international standards in the field of natural gas, which were jointly developed by China. These standards will provide a "Chinese solution" for global energy markets, offering cost reduction, efficiency improvement and security guarantees through precise quantitative indicators.

在页岩气开发方面，我国牵头的《页岩脆性指数测定和计算》系列国际标准，针对页岩气开发中优质储层识别难、压裂改造成本高的痛点，首次在国际层面规范了可压性评价技术框架。

In the field of shale gas development, the series of international standards led by China, namely "Determination and Calculation of Shale Brittleness Index", address the challenges of difficult identification of high-quality reservoirs and high costs of fracturing and modification in shale gas development. For the first time at the international level, this standard has established a technical framework for eva luating the compressibility.

国际标准化组织天然气技术委员会国内技术对口单位负责人 周理：特别在中后期开发的时候，如何使更多的页岩气能够快速稳定产出来。对于页岩气开发至关重要，基本上每一个标准至少有1万套数据来支撑。

Zhou Li, the head of the domestic technical counterpart unit of the International Organization for Standardization's Natural Gas Technology Committee: Especially during the later stages of development, how to enable more shale gas to be produced rapidly and stably. This is of crucial importance for shale gas development. Generally, each standard has at least 10,000 sets of data to support it.

应用该标准后，页岩优质储层的识别准确率预计能提升10%左右，可支撑单井勘探开发成功率从行业平均的65%提升至85%以上。单口页岩气井的作业成本可降低10%以上。

After applying this standard, the accuracy rate of identifying high-quality shale reservoirs is expected to increase by about 10%. This can support the success rate of single-well exploration and development from the industry average of 65% to over 85%. The operation cost of a single shale gas well can be reduced by more than 10%.

另外，《滑溜水性能测试和要求》标准是我国在页岩气领域牵头制定的首项产品国际标准。页岩气开发的关键技术之一是水力压裂，相当于用高压加液挤出天然气，而滑溜水是水力压裂的主要工作液，该标准系统规范了滑溜水的质量要求和性能测试方法，测试准确率提高至90%以上，将大幅减少贸易与仲裁纠纷。

Furthermore, the "Slurry Water Performance Testing and Requirements" standard is the first international product standard that China has led in the field of shale gas. One of the key technologies in shale gas development is hydraulic fracturing, which is equivalent to using high-pressure liquid injection to extract natural gas. Slurry water is the main working fluid for hydraulic fracturing. This standard systematically specifies the quality requirements and performance testing methods for slurry water, and the testing accuracy has been increased to over 90%. This will significantly reduce trade and arbitration disputes.

含硫气藏系列两项国际标准

Two international standards for sulfur-containing gas reservoirs series

破解天然气硫沉积与质量监测难题

Overcoming the challenges in monitoring sulfur deposits and quality of natural gas

在我国牵头制定的5项天然气领域国际标准中，有两项涉及含硫天然气，将破解硫沉积与质量监测的难题。

Among the five international standards in the natural gas field that were jointly formulated by China, two of them pertain to sulfur-containing natural gas and will solve the problems of sulfur deposition and quality monitoring.

全球已探明天然气储量中有约40%为高含硫气藏，这类天然气因为硫沉积问题导致开发难度极大。此次发布的《饱和溶解法测定元素硫溶解度》为安全清洁开发提供了科学手段，依托该标准可精准预测硫沉积趋势，建立含硫气田开发动态预警模型，为开发方案优化提供关键指标数据，预计能支撑单一气田年均增产约0.7亿立方米。

Approximately 40% of the globally proven natural gas reserves are high-sulfur gas reservoirs. Due to the problem of sulfur deposition, the development of such natural gas is extremely difficult. The recently released "Method for Measuring the Solubility of Elemental Sulfur by Saturation Dissolution" provides a scientific means for safe and clean development. Based on this standard, it is possible to accurately predict the trend of sulfur deposition and establish a dynamic warning model for the development of sulfur-containing gas fields, providing key indicator data for the optimization of development plans. It is expected to support an annual increase of approximately 70 million cubic meters in production for a single gas field.

周理：天然气输送过程中必须要把硫含量控制在一定的、很低的含量，不然它容易腐蚀管道，管道就可能会出现裂开、穿孔等情况。这次我们发布一个光学法，快速在线监控硫化氢的国际标准，来保证整个体系内精准监测硫化氢含量。

Zhou Li: During the transportation of natural gas, the sulfur content must be controlled at a certain and very low level. Otherwise, it will easily corrode the pipelines, and the pipelines may experience cracking or perforation. This time, we have released an international standard for an optical method for rapid online monitoring of hydrogen sulfide to ensure precise monitoring of the hydrogen sulfide content throughout the entire system.

《激光吸收光谱法测硫化氢》国际标准就是为天然气在线监测建立了高精度、高效率的国际统一技术规范，实现硫化氢等腐蚀性气体的快速精准检测，将检出限压低至0.1毫克/立方米，实现小于5秒的极速响应，检测效率较传统方法提升60%以上。依托该标准，全球超4万公里跨境管道可实现硫化氢含量实时精准监控，有效规避管道腐蚀与非计划停输风险。

The international standard "Laser Absorption Spectroscopy for Measuring Hydrogen Sulfide" has established a high-precision and high-efficiency international unified technical specification for online monitoring of natural gas. It enables rapid and accurate detection of corrosive gases such as hydrogen sulfide, reducing the detection limit to 0.1 milligrams per cubic meter and achieving an ultra-fast response time of less than 5 seconds. The detection efficiency is increased by more than 60% compared to traditional methods. Based on this standard, real-time and accurate monitoring of hydrogen sulfide content can be achieved on over 40,000 kilometers of cross-border pipelines worldwide, effectively avoiding risks of pipeline corrosion and unplanned shutdowns.

我国已牵头制定发布14项天然气领域国际标准

Our country has taken the lead in formulating and releasing 14 international standards in the field of natural gas.

截至目前，我国已牵头制定发布14项天然气领域国际标准，一百余名专家直接参与该领域国际标准制修订，并成功推动我国牵头的标准被英国、法国、德国、韩国、肯尼亚等欧亚非地区20多个国家采用。下一步，中国将继续推动科技创新与标准融合，让中国技术标准走向世界，为全球天然气产业发展贡献中国智慧。

As of now, China has taken the lead in formulating and releasing 14 international standards in the field of natural gas. Over 100 experts have directly participated in the formulation and revision of these international standards, and successfully promoted the standards initiated by China to be adopted by 20 or more countries in Europe, Asia and Africa, including the United Kingdom, France, Germany, South Korea, Kenya, etc. In the future, China will continue to promote the integration of scientific and technological innovation with standards, enabling Chinese technical standards to go global and contributing Chinese wisdom to the development of the global natural gas industry.
