As oil and gas resources are increasingly buried at greater depths, extraction has become ever more challenging. A high‑temperature, high‑pressure, high‑density mud‑compatible downhole packer for ultra‑deep wells has been developed, enhancing well completion performance and operational stability.
7 5/8-inch high-temperature, high-pressure (204°C, 105 MPa) hover-and-support acidizing completion packer
With the continued drilling of ultra-deep, ultra-high-temperature, and ultra-high-pressure gas wells, an integrated testing string has been developed to achieve both simplicity and effective well‑testing performance. The core components of this system include the RDS valve, RD valve, negative‑pressure test valve, and RTTS packer.
