9月9日，中国海油发布消息，随着恩平24-2油田第一口扩容调整井顺利投产，国内首个百米水深级油气原位扩容平台正式投入使用，标志着我国海上平台扩容增产技术实现新突破，对夯实海洋油气稳产基础、提升能源自主保障能力具有重要示范意义。

On September 9th, China National Offshore Oil Corporation (CNOOC) released a statement. With the successful commissioning of the first expansion adjustment well of the Enping 24-2 oilfield, the country's first oil and gas in-situ expansion platform at a water depth of over 100 meters has been put into use. This marks a new breakthrough in China's offshore platform expansion and production technology, and has significant demonstration significance for consolidating the stable production foundation of marine oil and gas and enhancing the country's independent energy security capabilities.

此次投产的恩平24-2油田扩容平台，位于深圳西南约200公里的珠江口盆地海域，作业水深近百米。项目采用“老平台原位加装新模块”的创新模式，在不停产、不重构原有生产系统的前提下，精准加装全新作业平台，新增12个井槽、可部署16口调整井，有效破解原有平台井位饱和、产能受限的发展瓶颈。据中国海油深圳公司恩平作业公司副总经理徐小虎介绍，项目成功攻克大型模块海上精准对接、平台扩容与系统兼容、百米水深环境下结构安全保障等一系列技术难题，创新实现“单钻机双平台共享”“40吨吊车V型移位”等多项国内首创工艺。

The expansion platform of the Enping 24-2 oilfield, which was put into production this time, is located in the Pearl River Mouth Basin off the southwest of Shenzhen, with an operational water depth of nearly 100 meters. The project adopts an innovative mode of "adding new modules to the existing platform in place", without stopping production or reconstructing the original production system. It precisely installs a new operation platform, adding 12 well slots and enabling the deployment of 16 adjustment wells, effectively solving the development bottlenecks of the original platform's well positions being saturated and production capacity being limited. According to Xu Xiaohu, the deputy general manager of the Enping operation company of China National Offshore Oil Corporation in Shenzhen, the project successfully overcame a series of technical challenges such as precise对接of large modules at sea， platform expansion and system compatibility， and structural safety guarantee in a 100-meter water depth environment. It innovatively achieved "shared use of a single drilling rig by two platforms" and "V-shaped relocation with a 40-ton crane" and other domestic first-in-the-world processes.

近年来，我国海上油气开发坚持新老并进，在推进新项目建设的同时，加快向存量提质增效转型，老油田挖潜增效成为海上油气稳产的重要支撑。恩平24-2油田于2014年10月投产，累计生产原油超1200万吨，是我国海上重要的在产油田之一。随着开发深入，原有平台井位饱和，无法满足剩余油气储量动用需求，通过加挂平台拓展钻井和生产能力，经济高效解决了老油田稳产增产难题。“与新建一座海上平台相比，恩平24-2油田扩容平台建设周期更短、投资成本更低，同时最大程度避免了海上施工对油田正常生产的影响，为我国海上老油田盘活存量资源、提升开发效益提供了可复制、可推广的解决方案，对保障海洋油气稳产增产、提升国内能源自主保障能力具有重要意义。”徐小虎介绍说。

In recent years, China's offshore oil and gas development has adopted a strategy of advancing both new and existing projects. While promoting the construction of new projects, it has also accelerated the transformation towards optimizing and enhancing the quality of existing assets. Exploiting the potential of old oil fields has become an important support for maintaining stable production of offshore oil and gas. The Enping 24-2 oilfield was put into operation in October 2014, with a cumulative production of over 120 million tons of crude oil. It is one of the important operating offshore oilfields in China. As the development progresses, the original platform well positions have become saturated, unable to meet the demand for the utilization of remaining oil and gas reserves. By adding platforms to expand drilling and production capacity, the problem of maintaining stable production in old oil fields has been economically and efficiently solved. "Compared with building a new offshore platform, the expansion of the Enping 24-2 oilfield platform has a shorter construction period, lower investment cost, and at the same time, avoids the impact of offshore construction on the normal production of the oilfield to the greatest extent. This provides a replicable and promotable solution for revitalizing the existing resources of old offshore oilfields and improving development efficiency in China. It is of great significance for ensuring the stable production and increase of offshore oil and gas and enhancing the domestic energy self-sufficiency capacity." Xu Xiaohu introduced.

据了解，该项目历时15个月建设，累计安全完成海上施工65.4万人工工时，实现平台连续安全生产超4350天，全程施工零事故、生产零中断，成为老油田升级改造标杆工程。

It is known that this project took 15 months to complete. A total of 654,000 man-hours of safe offshore construction were accomplished. The platform achieved continuous safe production for over 4,350 days throughout the entire process, with zero accidents and zero production interruptions. It has become a benchmark project for the upgrading of old oil fields.
