近日，中石油新疆油田采油二厂(以下简称“采油二厂”)81号天然气处理站的新建日产150万立方米浅冷装置正式投产。该站油田伴生气日处理规模跃升至390万立方米，成为国内最大油田伴生气处理站。

Recently, the newly-built shallow cooling facility with a daily processing capacity of 1.5 million cubic meters at the No. 81 natural gas processing station of the Second Oil Production Plant of China National Petroleum Corporation (hereinafter referred to as "the Second Oil Production Plant") was officially put into operation. The daily processing capacity of the station's associated gas from the oilfield has increased to 3.9 million cubic meters, making it the largest associated gas processing station in the country.

简单来说，油田伴生气处理就是把伴随石油一起被开采出来的天然气，通过一系列工艺进行净化、分离和回收，让它从一种可能造成浪费和污染的“废气”，变成有价值的绿色能源和化工原料。近年来，随着油气田逐步开发，采油二厂伴生气产量逐年攀升，旧设备难以满足生产需求。

In simple terms, the processing of associated gas from oil fields involves purifying, separating, and recycling the natural gas that is extracted along with the oil. This turns what could have been a waste and pollutant "waste gas" into valuable green energy and chemical raw materials. In recent years, as oil and gas fields have been gradually developed, the output of associated gas at the Second Oil Extraction Plant has been increasing year by year. The old equipment is unable to meet the production demands.

在天然气处理中，浅冷装置扮演着“冷凝分馏器”的角色。它通过降温，把伴生气中价值较高的较重成分“冷凝”成液体捞出来，同时把干净的轻质气体送出去。采油二厂此次新建的浅冷装置于2025年9月启动建设，采用了固体吸附脱硫、分子筛脱水及丙烷制冷脱烃工艺。

In the process of natural gas treatment, the shallow cooling unit acts as a "condensing distiller". It reduces the temperature to condense the more valuable and heavier components in the associated gas into liquid form and extract them, while sending out the clean light gas. The newly built shallow cooling unit of the Second Oil Production Plant was initiated for construction in September 2025. It adopts solid adsorption desulfurization, molecular sieve dehydration, and propane refrigeration for hydrocarbon removal processes.

施工中，新建浅冷装置创新采用了提前介入、边建设边整改的模块化工程验收模式，即每建完一个模块，就验收一个模块、整改一个模块，问题即刻反馈、整改同步推进。模块化验收模式仅用270天有效工期，便完成项目的建成投产，较原计划提前整整90天，大幅节约建设成本。

During the construction process, the newly-built cryogenic plant innovatively adopted a modular engineering acceptance model of "intervention in advance and rectification during construction", that is, after each module was completed, it would be accepted, rectified, and the problems would be immediately fed back and the rectification would be carried out simultaneously. With this modular acceptance model, the project was completed and put into operation within an effective construction period of only 270 days, which was 90 days ahead of the original plan and significantly reduced the construction cost.

作为新疆油田公司2026年度重点提质增效核心项目，新建浅冷装置的建成投用，标志着采油二厂老区稳产增效迈出关键一步，为新疆油田老区改扩建提供了标准化、可复制的建设范本。

As a key project for improving efficiency and achieving greater output in 2026 of Xinjiang Oilfield Company, the completion and commissioning of the newly-built shallow cooling unit marks a crucial step forward in maintaining stable production and enhancing efficiency in the old area of the Oil Production No.2 Plant. It also provides a standardized and replicable construction model for the expansion and renovation of the old area of Xinjiang Oilfield.
