中国石油网消息：5月6日记者获悉，华北油田巴彦油田CCUS-EOR先导试验核心采油井——兴华12-44X井，成功完成产液剖面测井作业。这标志着华北油田高凝自喷采油井常规工艺产液剖面测井取得重大突破。

China Oil News: On May 6th, reporters learned that the core production well of the CCUS-EOR pilot project in the Baian Oilfield of North China Oilfield - Xinghua 12-44X well - successfully completed the production fluid profile logging operation. This marks a significant breakthrough in the conventional logging of production fluid profiles for high-viscosity self-flowing production wells in the North China Oilfield.

产液剖面是指油气生产井在纵向各个射开层段当中，明确各层油、水、二氧化碳产出比例与流量，识别主力产油层、低动用层、产气层、含水层，判断二氧化碳在井筒与地层的分布、运移方向、突破位置，为后续气窜治理、调驱、提高波及体积提供必要资料保障。

The fluid production profile refers to the situation where, in each vertical section of the oil and gas production well, the output ratios and flow rates of oil, water, and carbon dioxide in each layer are clearly identified. The main oil-producing layers, low-productivity layers, gas-producing layers, and water-bearing layers are recognized. The distribution, migration direction, and breakthrough position of carbon dioxide in the wellbore and formation are determined. This provides necessary data support for subsequent gas migration control, stimulation, and improvement of sweep volume.

面对无成熟经验可循的难题，巴彦油田联合中油测井与专业技术服务队伍组建攻坚团队，开展全方位技术攻关。施工过程中，专业主管现场指挥，全程监督协调确保四方施工衔接流畅，缩短整体施工时间，协同加热电缆缠绕产液剖面测井防喷管保温，在最大限度上减少井筒、井口原油温度损失。历经35小时的连续奋战，团队实现设备完美适配、数据高质量采集、工艺一次成功。

Facing problems without any mature experience to follow, the Bayan Oilfield jointly formed an attack team with China Oil Logging and professional technical service teams to carry out comprehensive technical research. During the construction process, the professional supervisor was on-site to command, and the entire process was supervised and coordinated to ensure smooth coordination among all parties, shortening the overall construction time. They also collaborated to install the insulation pipe for preventing blowouts on the heating cable winding for liquid production profile logging. They achieved the goal of minimizing the loss of crude oil temperature in the wellbore and wellhead to the greatest extent through this effort. After 35 hours of continuous work, the team successfully achieved perfect equipment adaptation, high-quality data collection, and a successful process in one attempt.

此次突破意义深远，从数据价值看，获取的完整、精准产液剖面数据，为二氧化碳混相驱、油藏开发认识和综合治理决策提供科学依据。

This breakthrough is of profound significance. From the perspective of data value, the obtained complete and accurate liquid production profile data provide a scientific basis for the understanding of carbon dioxide miscible flooding, reservoir development, and comprehensive management decisions.

从经验价值看，本次成功探索积累了全套“高凝油自喷产液剖面”技术与管理经验，形成一套可复制可推广的“巴彦方案”，为同类型高凝采油井的测井作业提供实践范本。

From the perspective of practical value, this successful exploration has accumulated a complete set of "self-flow production profile of heavy oil" technology and management experience, and has formed a replicable and promotable "Bayan solution", providing a practical model for the logging operations of similar high-viscosity oil production wells.
