The 140 MPa ultra-high-pressure integrated cementing head independently developed by Sunshine Petroleum (Shangshan Petroleum) has been successfully put into service in ultra-deep well cementing operations at the Zhongyuan Southwest Project Department and Daqing Sichuan-Chongqing Project. The equipment operated stably throughout the process and satisfactorily fulfilled cementing tasks under high-pressure working conditions, building a solid safety barrier for ultra-deep oil and gas exploitation.

The ultra-high-pressure integrated cementing head deployed in this operation is core equipment tailor-developed by Sunshine Petroleum for high-pressure working conditions in ultra-deep well construction. During field operation, the equipment withstood continuous high-pressure loading stably without any leakage or malfunction. It efficiently coordinated with the on-site operating procedures and gained unanimous recognition from the project team.

✅ Technical Breakthroughs: Solving High-Pressure Cementing Pain Points from the Source

As oil and gas exploration extends to ultra-deep formations, the high-pressure and high-risk operating conditions of ultra-deep wells impose extremely stringent requirements on the pressure bearing capacity and reliability of cementing equipment. Traditional welded cementing heads are prone to weld cracking and seal failure, which have become critical bottlenecks restricting construction safety.

Through persistent technical research, the R&D team of Sunshine Petroleum has achieved multiple key breakthroughs with this newly developed cementing head:

Non-welded integrated structure: The integral structure eliminates all welding joints, completely avoiding stress concentration and weld failure risks, with a leading industry maximum pressure bearing capacity of 140 MPa.

High-reliability sealing design: All hammer union ports adopt a thread plus anti-loosening ring structure, achieving zero leakage under high-pressure environments.

Humanized operational design: The large plug accommodating cavity prevents negative pressure generation. The top cover is equipped with reserved spare interfaces and a plug ejector rod, together with a pin anti-rotation mechanism, comprehensively ensuring operational safety and construction efficiency.

✅ Deep Cultivation in Oil and Gas Equipment to Empower Deep Formation Development

The successful field application of this ultra-high-pressure cementing head not only verifies the technical strength and on-site adaptability of Sunshine Petroleum’s products, but also accumulates valuable engineering experience for the localization of ultra-deep well cementing equipment.

In the future, Sunshine Petroleum will continue to focus on the technical demands of deep and unconventional oil and gas development, continuously optimize product performance, and fuel the high-quality development of China’s oil and gas industry with safer, more efficient and more reliable equipment.
