Technical Specifications
1. Charge Geometry: The geometric shape of shaped charges of the SDP is especially for the system of H - 1 perforation. The shape is so made so as to focus the power of explosives in a well-regulated process, resulting in clean, deep, and well-regulated perforations.
2. Explosive Material: Such shaped charges employ high-energy explosives. The selected explosive is selected carefully in a manner so as to release maximum amount of energy and symmetrical detonation, which is of utmost priority in aiding in desired piercing depth and diameter.
3. Penetration Performance: Such charges have a penetrator capability of penetrating big depths in various forms of formations. The penetrations depth can be controlled depending on well requirements, for example, a few inches and greater than a foot, depending on other factors such as the hardnecks of formations.
Features
Stable Penetration
This product utilizes high-energy-density explosives, combined with a precisely controlled detonation velocity blending process, to achieve an average effective penetration depth of 10–14 inches. Its penetration profile is concentrated and stable, making it suitable for medium-hard and dense formations.
Precise Geometric Energy Focusing
The charge shape is optimized through numerical simulation, and explosive energy focusing control technology is applied to maintain a high axial concentration of the jet stream, with aperture size consistency controlled within ±0.5 mm.
Quick and Compatible Installation
The structural parameters strictly match the H-1 system. The charge and gun body are positioned using a modular interface, and a unified gun body guide and clip design enables single-shot loading within 3 minutes.
Multi-Dimensional Testing and Verification Mechanism
Each batch of charges undergoes detonation pressure testing, environmental stress testing, and high-temperature stability testing before shipment, simulating actual downhole conditions of 130°C and 20 MPa, ensuring performance without deformation or detonation deviation under complex wellbore conditions.
Quality Control
1. Manufacturing Standards: Strict international manufacturing standards of a stringent kind exist in manufacturing shaped charges of SDP. Each of these is inspected stringently for its quality in every manufacturing process so as to provide constant functionality and stability.
2. Testing Procedure: The shaped charges go through various testings before release for usage, for example, detonation test, test for penetrations, and environmental test. The trials make efforts to simulate actual environments in an effort to legitimize functionality and durability of the charges.
Safety Features
1. Insensitive Designing: The shaped charges of SDP have been rendered insensitive to unwanted vibrations, shock, and electrical discharge. This makes such shaped charges non-spontaneous in detoning in case of mounting, handlings, and transportation.
2. Safety Interlocks: With integration of the H - 1 system of perforation, there is inclusion of safety interlocks in an effort to prevent unwanted firings. The interlocks ensure that in controlled and secure environments, there can be detonation of the charges.

FAQ
Q: Is the penetration depth suitable for dense or high-strength formations?
A: Yes. The charge utilizes high-energy explosives and a focused charge structure, enabling stable penetration through medium- and high-strength formations while maintaining high penetration quality.
Q: Is there a risk of explosion during transportation?
A: No. The charge is designed to withstand seismic and electrical shock, meeting transportation safety standards and minimizing the risk of unintended detonation during normal transportation.
Q: How is the consistency of each batch of charges ensured?
A: Each batch undergoes detonation performance and environmental compatibility testing before shipment to ensure consistent performance.
Q: Does the loading process require special tools?
A: No. The product complies with the H-1 system interface standard and can be assembled directly on-site. Operation is simple and requires no additional tools.
