core Features
High-precision shaped charge jet
Using CFD (Computer Dynamics Design) to optimize the shaped charge chamber geometry, the metal jet velocity exceeds 8,000 m/s, with the jet axial deviation controlled within 1°, improving penetration consistency and effective penetration depth.
Stable lining material
The lining is made of high-purity copper alloy, processed by CNC machining and heat treatment, with a hardness controlled between HV110 and HV130. This ensures a continuous and stable jet flow without cracking or deformation in high-temperature and high-pressure environments.
Low explosive loading error
Explosives are loaded using an automatic weighing control system, achieving a charge error of less than ±1% per round. Combined with an electrostatic shielding filling device, this improves energy release stability and reduces the risk of perforation failure.
Full-process factory inspection
X-ray nondestructive testing verifies internal structural integrity. On-site equivalent testing in a high-temperature and high-pressure simulation chamber ensures that penetration depth and aperture deviation are controlled within 5%, ensuring that each batch meets the H-1 system application standards.
Manufacturing Process
- Charging with Explosive: The charges contain specially adapted explosive material. The method of explosive loading is well controlled in order to deliver uniform energy output. Sophisticated methods are used to keep the explosive well under control in the charge in order to prevent under- or over-performance.
- Assembly: Assembly of the BH shaped charges for the H - 1 perforating gun is done in a clean and controlled environment. All the components, such as the liner, explosive, and casing, are inspected before assembly to meet high - quality standards. Automated assembly lines can be used to offer accuracy and repeatability.
Quality Control
- Testing Procedures: Extensive testing is carried out at different stages of manufacturing. Non-damaging tests like X-ray inspection are applied to verify internal flaws in the charges. Live firing tests are also done under simulated downhole conditions to verify the performance of the charges, i.e., depth of penetration and diameter of the hole.
- Compliance Standards: The production is in accordance with international standards and industry best practices. For instance, it can be in accordance with API standards to guarantee the reliability and safety of the BH shaped charges for application in the H - 1 perforating gun in various oil and gas fields globally.
Packaging and Storage
- Packaging: The fees are packaged in specially designed containers that shield them from physical shocks, moisture, and electrostatic charge. Packaging is designed to endure the rigors of shipping and storage under different conditions.
- Requirements for Storage: They are retained in temperature-controlled and humidity facilities. Safety mechanisms against accidental firing are installed in order to inhibit unintentional explosion, and optimized inventory management tools are used for monitoring the charges from production up to deployment.
