There are many parameters involved in perforation, such as perforation depth, perforation density, perforation phase angle, formation anisotropy, the radius of the perforation hole and so on. These parameters affect the production capacity of oil and gas wells after perforation. Comprehensively consider the influence of each parameter according to the actual situation of the formation, so that the production capacity of oil and gas wells  could be largest.

It is known that the parameters of the perforation depth, the perforation density, the perforation phase angle, the anisotropy of each phase of the formation, the radius of the perforation hole and so on, the production capacity of the actual oil and gas well is calculated, and the skin factor (the perforation skin, the damaged skin, the total skin) are also given.

Given a certain perforating gun, the perforation optimization design is carried out, that is, with known perforation depth, the anisotropy of the  formation and the radius of the perforation hole, calculate the productivity of oil and gas wells with different perforation density, phase angle and format, so as to select the scheme with best economic benefit.

The parameters like the perforation depth are known, the three-dimensional pressure distribution under the unstable condition is calculated, the numerical value of the bottom hole pressure varies with time of the slug flow or the  self-production well under the unstable condition is calculated and the curve is plotted, And calculating the value of the section plug flow bottom hole flowrate over time and drawing a curve.

The parameters of perforation depth and so on are known, and the curve of the flow over time under different pressures is calculated, and the effect of different perforation parameters on the perforation production ratio (sensitive parameter analysis) is given.

Optimized perforating technology based on the guaranteed wellbore safety, the p-t curve is obtained by the explosion calculation of the perforating bullet in different loading, different pore density and different perforation format, and the safety pressure of the casing is calculated to achieve the purpose of process design optimization.
