In the conventional perforation and special well perforation construction, because the perforator is on one side of the casing and the gap between the barrel wall and the casing wall is different, the perforation hole diameter on the casing wall is not uniform with the formation perforation channel, which reduces the conductivity of the perforation channel, affects the subsequent hydraulic fracturing construction effect, and even affects the subsequent development and transformation effect. Through theoretical analysis and ground test of conventional four-phase perforator with the degree of 90 and three-phase perforator with degree of 120 in horizontal well, the centering device in vertical well and rotary centering device in highly deviated well are designed, and the equal aperture perforating charge is developed to realize uniform perforation in technology and equipment. After perforating, the hydraulic fracturing pressure is reduced by 11.2% compared with conventional perforating. The technology can be applied to large-scale fracturing of tight oil and gas horizontal wells and conventional perforating fracturing wells to meet the needs of oilfield hydraulic fracturing development and transformation.
