• The 2025 version of the standard expands coverage to include complex well conditions, including HPHT wells, shale gas wells, natural gas wells, gas storage wells, thermal recovery wells, and CCUS/CCS-related well types. This reflects the evolving nature of China's drilling activity toward more technically demanding applications. Industry standards for cementing equipment and operations, including SY/T 5374.2-2023 on special cementing procedures and SY/T 5557-2025, provide additional technical requirements.
• National standards for deepwater cement testing have been introduced. GB/T 33294-2025 "Testing of Deepwater Well Cement," published in August 2025 and effective from December 2025, provides specific methodologies for cement testing in deepwater environments. SY/T 6641-2025, published in September 2025 and effective from March 2026, establishes specifications for cement bond log data processing and interpretation.
• China's energy-equipment policy framework supports the domestic development of drilling, completion, cementing, and related oilfield equipment, while decarbonisation policies are encouraging R&D into lower-emission oilfield technologies. The Energy Law and national industrial support policies provide the legislative foundation for oil and gas development. China's national oil companies - CNPC, Sinopec, and CNOOC - remain the primary drivers of drilling and cementing activity.

Well Cementing Services Procurement & Industry Impact

• Procurement in the Chinese well cementing services market is dominated by the three national oil companies: CNPC, Sinopec, and CNOOC. These NOCs conduct the vast majority of exploration, development, and production activities and procure cementing services through their affiliated oilfield service subsidiaries. COSL, the primary offshore service provider, generated substantial revenue in 2025, with its Oilfield Technical Services segment providing cementing and completion services.
• Onshore cementing services are primarily provided by CNPC and Sinopec's oilfield service subsidiaries. Sinopec Oilfield Service Corporation reported significant revenue and net profit in 2025, with cumulative newly signed contracts reaching record levels. The market is characterised by strong vertical integration, with NOCs relying heavily on their affiliated oilfield service companies while also using competitive procurement and external suppliers for selected projects, technologies, and specialised services.

Segment Analysis

China Well Cementing Services Market By Service Type
• Primary cementing in China spans high-volume onshore drilling, offshore development and an expanding ultra-deep drilling programme. The Tarim Basin's extreme-depth wells require cement systems capable of maintaining integrity under severe HPHT conditions, while shale-oil demonstration activity adds another technically distinct application. Offshore projects introduce additional requirements for temperature control, pressure management and long-term barrier reliability. This combination means that cementing demand is distributed across very different well architectures, with laboratory qualification and specialised placement technology becoming increasingly important for the deepest and most complex wells.
• Remedial cementing is supported by mature producing assets in established basins such as Daqing and Shengli, where operators continue to pursue recovery improvements and production-decline management. Intervention work includes squeeze operations, casing repair, workovers and other integrity treatments designed to keep ageing wells productive. Offshore fields add another layer of complexity because intervention must often be performed within tighter operational windows. The focus on reducing natural decline therefore creates a continuing requirement for cement-integrity evaluation and targeted remedial treatments alongside new-well cementing.
China Well Cementing Services Market By Well Type
• Oil wells generate substantial cementing demand across China's mature producing fields and emerging developments. Daqing and Shengli, the largest conventional oil fields, maintain long-term stable production through reservoir management and enhanced recovery. Shale oil production reached significant levels in 2025. The Ordos Basin achieved substantial oil and gas equivalent production. Oil-well cementing requires engineered slurry systems capable of maintaining zonal isolation under challenging production conditions.
• Natural gas wells represent a strategically important segment, supported by China's large and growing domestic natural gas production and consumption base. The Sichuan Basin's gas production accounted for a substantial portion of national production growth, while unconventional gas continues to contribute to China's expanding supply base. Continued drilling of conventional and unconventional gas wells across major producing basins sustains demand for primary and remedial cementing services. Cementing in gas wells requires particular attention to pressure integrity and annular isolation, with the new SY/T 5480-2025 standard adding specific requirements for gas well cementing.
China Well Cementing Services Market By Deployment
• Onshore drilling requires repeatable cement placement across thousands of wells annually in the Ordos, Sichuan, Tarim, and other major basins. Onshore cementing is characterised by high volume, rapid mobilisation, and cost-sensitive procurement. The ultra-deep drilling campaign in the Tarim Basin, including the record-depth Shendi Take-1 well, requires specialised cementing solutions capable of withstanding extreme HPHT conditions. Shale oil and gas development in Sichuan and other basins sustains onshore cementing demand.
• Offshore drilling in the Bohai Sea, East China Sea, and South China Sea requires specialised cementing solutions adapted to different water depths, temperature conditions, well architectures, and formation pressures. Deepwater and ultra-deepwater projects in the South China Sea impose additional requirements for low-temperature cement behaviour, pressure control, and long-term well integrity, while national standards including GB/T 33294-2025 provide specific methodologies for deepwater well-cement testing. CNOOC's offshore drilling efficiency increased through the deployment of intelligent drilling and completion technologies, while the "Haiheng" wellbore fluid technology system covers cement slurries across multiple operating scenarios. Offshore cementing generally involves lower activity volumes than China's extensive onshore market but higher technical intensity and equipment requirements.
