Abstract
In order to improve the penetration performance of perforating charges under actual reservoir conditions and enhance the recovery rate of oil and gas wells,combined with the rock characteristics of sandstone reservoirs,a method combining numerical simulation and multi-objective genetic algorithm was adopted to optimize the structure of the shaped charge liner.The key dimensional parameters that affect the penetration performance of the shaped charge liner have been determined to be the outer wall opening angle a,outer vertex angle radius b,inner vertex angle radius c,and inner wall opening angle d.A response surface methodology was used to establish an explicit expression for penetration depth in rela-tion to these parameters.The results indicate that the optimal structural dimensions for the shaped charge liner of the perfo-rating charge are:a at 40°,b at 3.837 mm,c at 2.813 mm,and d at 38.7°.The simulation calculations and experimen-tal tests after structural optimization show that the penetration performance of the perforating charge has been improved,with penetration performance on sandstone targets increased by 28.97%and 20.60%,respectively.It significantly improves the penetration performance of perforating charges in rock formations,providing corresponding technical support for efficient development of oil and gas fields.关键词
