As UAVs play a greater role in military operations, the pressure to reduce volume and weight is also increasing. Aerospace UAV Connectors are an important basic component that is almost ubiquitous in military and aerospace aircraft & UAV applications and serve as interconnects for transmission signals and power, which has to meet stringent testing for outgassing and residual magnetism to be suitable for use in airspace & UAV applications. Outgassing and residual magnetism can adversely affect nearby components.

Weight & space-saving is necessary for aircraft & UAV connectors because there is only so much room on a space vehicle. They have to be extremely reliable as well and they must resistant to severe environmental conditions like shock, radiation, extreme temperatures, and vibration. In the case of high vibration, shock and temperature cycling, the board to board or box to box connectors of UAV and its cables must also be highly reliable.

Perforation Gun, A device used to perforate oil and gas wells in preparation for production. Containing several shaped explosive charges, perforating guns are available in a range of sizes and configurations. The diameter of the gun used is typically determined by the presence of wellbore restrictions or limitations imposed by the surface equipment.

Perforation is an extremely important technique in petroleum exploration and recovery engineering, a major means of enhancing the recovery factor of gas and oil wells and also a typical method of tapping the potential of existing oil fields and increasing output.

Perforation completion is widely used worldwide and accounts for about over 90% of all well completions. Almost all reservoir beds can be opened by this method. In the method, in the course of gas and oil field exploitation the production casing is lowered and cemented and then special perforation instrument and devices are sent down to the predetermined depth and aimed at the target layer.

Through the key parts, the firing head connector

The perforator down in the well is ignited from the ground and the lined cavity charge (The propellant material is potassium perchlorate, an oxidizer that burns rapidly, creating CO2. As the shaped charges detonate, the propellant is ignited by extreme heat from the gun system. As it burns, the propellant generates CO2 at high peak pressures typically well above the formation fracture gradient.) is ignited which result in the detonation wave to transmit forward at a velocity of 7~8 km per second and high temperature and high-pressure shock waves are generated which penetrate through the casing, cement sheath and enter the stratum forming a hole canal, as illustrated by the diagram. Whichever perforation method you use, the performance and quality of the perforating gun (Including the perforating gun pipe) shall have a significant influence on the perforation quality of gas and oil wells.

Benefits / Capabilities of Sunkye Firing Head Connector

Can re-perforate in old well without pulling the tubing out.

Can be used with big charges to achieve deeper penetration.

Firing circuitry is in short before the charges are released.

Dual Pressure random mounting side

Circulation flexibility—allowed in both directions before and after the guns are fired. Underbalanced perforating conditions are easily established.

CT compatibility—the firing head can take a combination of shear pins and can be connected to any CT string by means of a crossover connector.

Soldering mounting terminal Design efficient assembly to the equipment

Ultra-tiny design fit for the drill head solution and equipment

LAB TEST DATA

Assembly & Mounting Steps

Step 1: Annulus pressure from above the packer enters the crossover tool and is applied to the first (bottom) time delay firing head. The first Sunkye firing sub prevents pressure from reaching the second firing head. The time delay provides time to bleed off pressure. When the guns detonate, the firing train continues to the firing sub. The sub fires, creating a path to the second firing head. The zone is tested.

Step 2: Annulus pressure is reapplied and travels to the second time-delay firing head. The first pressure isolation sub prevents pressure from venting through the first set of perforations. The pressure is released, the gun fires and the second Select Fire sub fires and opens a path to the third gun. Production from the second zone is commingled with pressure from the first zone for testing.

Step 3: Pressure applied to the annulus passes through the annulus pressure crossover and down the control line to the third time-delay firing head. The second pressure isolation sub prevents pressure from venting through perforations in the first and second zones. The pressure is released, the guns fired, and flow from all three are commingled for testing.
