What are the Work Principles Of Oil Perforating Gun?

Perforating gun is one of the key tools for perforating operation, which has a great impact on the quality of perforating. The inside of the perforating gun is a highly sealed space, which plays a role in separating perforating bullets, detonating cords, detonators, etc. from the well fluid during the work process. But oil perforating gun is mainly referring to oil drilling construction.

When perforating bullets are used for perforating operations, the explosion of perforating bullets will produce a relatively severe impact force. At the same time, it will act on the two ends of the perforating gun together with the gas pressure generated after the powder is burned. When designing, it is not only necessary to ensure that the gun body has a high bearing capacity, but the connecting bolts at the gun head and the gun tail should also have high strength, and it is necessary to pay attention to the reasonable selection of the materials used. In addition, when designing the structure of the oil perforating gun, it is necessary to pay attention to other details. Through continuous optimization and improvement of the details, the performance can be better guaranteed.

Overview and principle of petroleum perforating gun

Oil perforating gun mainly carry sealing components for directional blasting of perforating bullets. They are usually divided into gun body, gun head, gun tail and other parts. The whole is made of seamless steel pipe, and blind holes are provided on the outer wall of the steel pipe . The perforating guns commonly used at the present stage are classified according to the conveying method, perforating method, and recycling method.

In actual work, after all preparations are completed, the perforator is detonated, and the detonating cord will explode at a high speed and high pressure, and then detonate the perforating bullet filled in the perforating gun. After the explosive in the perforating bullet explodes, it will release a very strong impact force. This impact force will act on the conical bushing in the perforating bullet, which will cause it to receive thrust from the axial direction and concentrate together. At one point, the force acting on the top position of the conical bushing will be subjected to ultra-high pressure, pushing it forward at an extremely high speed, and then penetrating the casing, the cement ring and the formation to obtain the required perforation channel. 

Perforation is the most important link in the exploration and development of oil and gas fields. In order to deepen the potential of oil and gas geological reserves, the perforating technology using the combination of perforating projectile flow and gunpowder combustion work has been widely used at home and abroad due to the significant increase in production of low permeability reservoirs. The major oil companies attach great importance to and applications.
